Abstract:
AbstrakItsmun adalah istilah yang digunakan dalam al-Qur’an yang dipakai sebagai istilah dosa, yang mempunyai makna perbuatan-perbuatan yang menghambat tercapainya pahala. Itsmun dengan kata lain adalah sebutan atas tindakan yang menghambat tercapainya (terwujudnya) kebaikan. Itsmun di dalam al-Qur’an digunakan untuk menyebutkan sebuah pelanggaran yang memiliki efek negatif terhadap diri sendiri dan masyarakat. Maka itsmun dikatakan dosa apabila perbuatan tersebut merupakan perbuatan yang telah merugikan diri sendiri dan orang lain. Itsmun dalam pemaknaannya banyak disampaikan oleh kalangan sufi, khususnya dalam menafsirkan ayat-ayat yang terkait dengan Itsmun. Imam Al-Alusi merupakan tokoh mufassir klasik yang ternama, khususnya pada kalangan ulama tasawuf yang menggunakan tafsir aliran sufistik isyari. Pemikiran Al-Alusi dalam tafsir Rûh al-Ma’ânî tidak terlepas dari kiprah beliau dalam konteks idiologi beliau mengenai prihal aqidah. Adapun mengenai penafsiran beliau tentang ayat-ayat itsmun, Al-Alusi tidak terlepas dari kesufiannya dalam pemikirannya. Penelitian ini termasuk dalam jenis penelitian pustaka (library research) dengan menggunakan metode deskriptif analitis yang pokok kajiannya pada kitab tafsir Rûh al-Ma’ânî. Dengan menggunakan metode tersebut, peneliti mendapati secara umum Al-Alusi menyatakan bahwa itsmun adalah orang yang banyak dosa, orang kafir, kebohongan, serta dalam setiap ayat mengandung makna yang melawan Allah dan Rasul, serta memiliki efek negatif terhadap diri sendiri dan orang lain. Adapun solusi yang diberikan terhadap orang yang berbuat dosa yaitu dengan cara bertaubat kembali kepada petunjuk Allah dan menjauhi semua larangannya serta tidak mengulangi perbuatan dosa lagi.Kata Kunci: Itsmun, Tafsir Isyari, Imam al-Alusi

Abstract:
Razi dan Tafsir Ruh al-Ma’ani karya al-Alusi? (2) Bagaimana Metode Penafsiran dalam kitab Tafsir Mafatih Al-Ghaib karya Fakhruddin Al-Razi dan Tafsir Ruh al-Ma’ani karya al-Alusi ?. Penelitian ini merupakan jenis penelitian library research (kepustakaan). Metode penelitian yang digunakan adalah metode Tematik-Deskriptif-Analisis. Teori yang digunakan adalah Hermeneutika Jorge J.E.Gracia dengan menggunakan pendekatan fungsi Historis Gracia. Berdasarkan hasil penelitian dan analisis dapat disimpulkan bahwa: term Qiradah dalam Al-Qur’an disebutkan sebanyak 3 kali, yakni dalam surah al-Baqarah ayat 65, al-A’raf ayat 166, dan al-Maidah ayat 60. Fakhruddin al-Razi ketika menafsirkan kata Qiradah ia menafsirkan dengan makna haqiqi yaitu perubahan bentuknya, sedangkan al-Alusi menafsirkan dengan makna majazi atau sifatnya. Perbedaan kesimpulan yang terjadi antara keduanya dalam menafsirkan kata Qiradah dapat dilihat dari sisi metodologi penafsirannya, historisitas kehidupan antara keduanya, dan lainnya. Al-Razi hidup di masa Daulah Abbasiyah yang merupakan masa berkembangnya berbagai diskusi di segala cabang ilmu pengetahuan, sehingga secara tidak langsung ilmu-ilmu aqliyah sangat mendominasi pemikiran al-Razi di dalam tafsirnya. Sedangkan al-Alusi menafsirkan secara makna majazi, karena berbagai aliran sufistik pada masa kehidupannya sangat kuat.

Abstract:
Ruh Al-Ma’ani karya al-Alusi merupakan salah satu kitab tafsir yang mengkombinasikan dimensi zahir (eksoteris) dan batin (esoteris) dalam penafsiran ayat-ayat al-Qur’an. Tulisan ini membahas praktek tafsir Isyari dalam Kitab Ruh al-Ma’ani dengan referensi penafsiran ayat-ayat ibadah. Pertama-tama penulis memaparkan teoritisasi tafsir isyari sebagai salah satu pendekatan dalam memahami kandungan makna ayat-ayat al-Qur’an. Kemudian penulis memaparkan topografi ayat-ayat al-Qur’an yang ditafsirkan secara Isyari dalam kitab Ruh al-Ma’ani. Pemaparan kemudian berfokus membahas praktik penafsiran dengan metode Isyari dalam kitab Ruh al-Ma’ani terhadap ayat-ayat yang berkaitan dengan ibadah shalat, puasa, zakat dan haji. Tulisan diakhiri dengan kesimpulan yang mempertegas pandangan bahwa penafsiran al-Alusi terhadap ayat-ayat ibadah dengan metode Isyari sebagaimana dilakukan al-Alusi tidak pada posisi yang mempertentangkan antara dimensi zahir dan batin ayat-ayat tersebut.

Abstract:
Not infrequently, there is a gap between Sufi idealism and the reality between worship carried out in the Shari'a and Riyadah carried out. So it is not uncommon for lay views to show sinful acts. This is the background for researchers to focus on the interpretation of al-Qusyairi and al-Alusi on the word ithm in the Koran. This study aims to analyze the understanding of ithm in the perspective of two Sufi commentators more deeply. The approach used is the semantic theory according to Toshihiko Izutsu, the irfâni epistemology theory according to Abid al-Jabiri and the muqâran (comparative) method according to al-Farmawi. The results of this study are as follows: First, al-Qushairi interprets the word ithm in general, and focuses more on the context of the perpetrator. Meanwhile, al-Alûsi analyzes it in more detail with various contexts. Al-Alûsi interprets lafadz Ithm with the meaning of sin or a job that hinders the reward.

Abstract:
This study aims to explain the foundations of the critical methodology of Imam Al-Alusi in his recantation of Imam Al- Fakhar Al-Razi opinions. The researcher chose this topic to conduct a study on it because both of the exegeses have great value and high status in exegeses field. They contain various benefits and useful matters in different sciences related to the holy Qur’an. Also, knowing the recantations are of great significance in identifying the foundations on which Imam Al- Alusi critical methodology was based. This paper shows how he applied this methodology to criticize the opinion of past exegetes especially Imam Al-Fakhar Al-Razi. In this study researcher has used the inductive extraction and descriptive method of research to discuss the critical methodology followed by Imam Al- Alusi. He refutes the opinions of Imam Al-Fakhar Al-Razi in various issues related to the exegesis.

Abstract:
The importance of interpretation comes from the Holy Qur’an itself. Because the honor of a thing is honored by an honor related to it; As the interpretation clarifies and clarifies what the Qur’an came with, and since the Qur’an is the miraculous book of God and the first source of legislation, the interest in its interpretation was great, and the interpretation in the tradition was one of the sections of exegesis. Among the commentators appeared to be those who responded firmly to these narrations and criticized them, and among their myths and delusions. Al-Alusi was among the few commentators who criticized these Israeli women and confronted them. The research plan necessitated dividing it into two topics. In the first topic, I dealt with the definition of Israeli women and Al-Alusi's position on them. In the second topic, I dealt with the approach that Al-Alusi followed in his criticism of Israeli women, and then a conclusion about the most important findings drawn from the research. It is worth noting that I mention the total of the narratives that Al-Alusi criticized, which amounted to seventy-one novels, but I was not able to include all of them in this research due to their abundance and length, so I confined to what al-Alusi criticized with irony and sarcasm, and what he criticized based on sources that he relied on in his interpretation, as for the rest of the narratives that he criticized.

Abstract:
The major problem discussed in this article is the presence of domestic violence conducted by husbands towards their wives in their marriages. Several verses of the Qur’an have been used to legitimize these arrogant actions. Using religious texts and culture of patriarchy, domestic violence seems to persist. This article discusses the interpretation of some verses of the Qur’an, especially the mystical interpretation, which is related to the rights of wives in marriage. Two mystical interpretations are the case of the study, i.e., Ruh al-Ma‘ani of al-Alusi and al-Fawatih al-Ilahiyya of al-Jilani. This article describes analytically and critically explores the ideas of al-Jilani and al-Alusi about women’s rights in Islam.

O estudo do processamento de compósitos de matriz metálica pelo método de fundição com agitação é de grande interesse em engenharia pelo seu baixo custo e possibilidade de utilizar equipamentos convencionais de fundição. Nesse trabalho é feito o estudo do processo de síntese de compósitos da matriz da liga A356 reforçada com partículas de alumina, focalizando a influência dos fatores de processo na fração de partícula incorporada. Foram sintetizados lingotes de compósitos variando as condições de processo. Foram desenvolvidos métodos específicos de amostragem estatística associados à análise e processamento de imagens e utilizados na obtenção de estimativas confiáveis da fração volumétrica. Para investigar a influência dos fatores e suas interações foi projetado um experimento fatorial com 4 fatores, definidos em ensaios preliminares. Os resultados confirmam achados teóricos e experimentais anteriores e indicam novos caminhos para se obter uma melhor incorporação de partículas, além de um entendimento do mecanismo da molhabilidade da liga no estado semissólido. Compósitos com maior grau de partículas incorporadas foram examinados por microscópio eletrônico de varredura e microscópio óptico, mostrando que a partícula se aloja preferencialmente na região interdendrítica da matriz.

Abstract:
Tiivistelmä. Tämän pro gradu -tutkielman tarkoituksena oli selvittää, millaisia käsityksiä ensimmäisen vuosikurssin opiskelijoilla oli teknologiapainotteisesta luokanopettajakoulutuksesta opintojen alussa, miten käsitykset mahdollisesti muuttuivat opintojen edetessä, miten opiskelijat käsittävät koulutuksensa painotuksen ja teknologiakasvatuksen. Lisäksi tutkimus avaa, miten opiskelijat päätyivät opiskelemaan teknologiapainotteiseen luokanopettajakoulutukseen. Tutkimuksen teoreettisessa viitekehyksessä tarkastellaan käsitysten muodostumista, teknologiapainotteisen luokanopettajakoulutuksen ja teknologiakasvatuksen luonnetta. Käsitteet ja käsitykset muodostavat perustan, jolla ihmiset tulkitsevat ympärillään olevan maailman ilmiöitä. Teknologiapainotteinen luokanopettajakoulutus on yksi Oulun yliopiston luokanopettajakoulutuksen painotuksista, jossa opiskellaan kasvatustiedettä ja painoalana on teknologiakasvatus. Teknologiakasvatuksen tavoitteena on tekemällä oppimisen avulla teknologisen yleissivistyksen edistäminen ja elinikäinen oppiminen. Tutkimus on luonteeltaan kvalitatiivinen ja lähestymistavaltaan fenomenografinen. Tutkimukseen osallistui yhteensä 13 opiskelijaa, jotka olivat aloittaneet opiskelun teknologiapainotteisessa luokanopettajakoulutuksessa syksyllä 2015. Tutkimuksen aineisto kerättiin vuoden 2016 helmikuussa kyselylomakkeiden avulla. Aineisto analysoitiin aineistolähtöisen sisällönanalyysin menetelmien mukaisesti. Aineiston analysoinnissa on kuitenkin teoriaohjaavan sisällönanalyysin piirteitä. Tutkimustuloksista voidaan todeta ensimmäisen vuosikurssin opiskelijoiden käsittävän teknologiapainotteisen luokanopettajakoulutuksen opintojen alussa sen substanssitason käsitteiden avulla. Käsitteellinen muutos tapahtuu opintojen edetessä koulutuksen luonteen ja teknologiakasvatuksen ymmärtämisen kehittyessä. Vaikuttavina tekijöinä muutoksiin ovat opettajat, muut opiskelijat ja opiskeltavat kurssit. Tutkimusjoukosta suurin osa ei hakenut opiskelemaan teknologiapainotteista luokanopettajakoulutusta ensimmäisenä vaihtoehtonaan. Aiheesta ei ole tehty aiempaa tutkimusta ja yhden vuosikurssin otannan perusteella ei voida tehdä yleistyksiä. Tutkimuksen tulokset antavat suuntaa, miten painotuksesta saatavaa käsitystä pystyttäisiin kehittämään painotuksen luonnetta kuvaavammaksi, jotta koulutukseen hakeutuisi opiskelijoita, jotka kokisivat painotuksen omakseen.

Abstract:
By continued advances in mechanical strength of press hardened boron alloyed steel (22MnB5) weight savings can be achieved by the use of less material. However, with reduced material thickness stiffness problems such as buckling arises and the high strength of the material can’t fully be taken advantage of. A solution to the stiffness problem could be to create a sandwich structure using 22MnB5 steel. To create a sandwich structure the faces have to be joined to the core. Work has been done concerning various methods of joining both coated and uncoated 22Mnb5 after being press hardened. A more direct approach would be to implement a joining process in the hot stamping line prior to forming and quenching. A joining method suitable for this task is Controlled Atmosphere Brazing (CAB), which today is used for both aluminum and steel brazing and could be implemented in a hot stamping furnace. Using a tube furnace with continuous gas flow of N2 overlap braze joints were produced on both AlSi-coated 22MnB5 (USIBOR® 1500P AS150) and plain 22MnB5. Material combination evaluated included two different brazing foil and two different flux paste in combination with various heat cycles. Both one-step braze cycles with brazing directly at austenite temperature and two-step braze cycles with brazing at a lower temperature followed by heat treatment at austenite temperature were developed. Evaluation of braze joint strength was done using tensile testing and the same was done to evaluate the coating strength of USIBOR® 1500P AS150 after heat treatment using adhesive to create an overlap joint. An adhesion pull-off test was used to determine USIBOR® 1500P  AS150 coating strength after various heat cycles. Scanning Electron Microscope (SEM) with Energy Dispersive Spectrometry (EDS) was used to investigate amount of Fe-diffusion from substrate into both coating and joint due to heat cycles and to determine phases connected to fracture location of joints. With NiCr-based brazing foil joints between plain 22MnB5 were produced with a braze time of 10 minutes at 950° C that had an avg. shear strength of 20 MPa. Brazing above the liquidus temperature of the filler material for 5 minutes with a higher furnace temperature showed no decrease in shear strength of joints, but reduced time in furnace by 16 minutes giving a total furnace time of 9 minutes. Best results for joints between USIBOR® 1500P AS150 substrates were achieved using a two-step brazing cycle. Brazing was done at 593° C for 35 minutes with AlSi12 brazing foil and flux paste recommended for aluminum brazing. Afterwards specimens where heated for 4 minutes above austenite temperature and had an avg. a shear strength of 5,4 MPa. EDS-analysis showed that fracture in braze joints and in coating of USIBOR® 1500P AS150 was connected to the intermetallic phase Al5Fe2 as well as Fe-diffusion from substrate was higher than in as received conventionally press hardened USIBOR® 1500P AS150. Adhesion pull-off tests indicated that the heat cycles used in this study significantly reduced coating strength compared to as received conventionally press hardened USIBOR® 1500P AS150.
Genom fortsatta framsteg inom hållfasthet av presshärdat borstål (22MnB5) kan viktminskning erhållas med mindre material användning. Med reducerad materialtjocklek uppstår dock styvhetsproblem som buckling och den höga styrkan hos materialet kan inte utnyttjas fullt ut. En lösning på styvhetshetsproblemet vore att skapa en sandwichstruktur med användning av 22MnB5 stål. För att skapa en sandwichstruktur krävs fogning mellan täckskikt och kärna. Arbete har utförts på olika fogningsmetoder för både belagt- och obelagt-22MnB5 efter att det genomgått press härdning. En mer direkt metod vore att implementera fogningsprocessen i presshärdningslinan i ett skede innan formning och släckning. En fogningsmetod lämpad för detta ändamål är Kontrollerad Atmosfärslödning (CAB) som idag används för såväl aluminium- som stållödning och skulle kunna implementeras i en presshärdningsugn. Med hjälp av en rörugn med kontinuerligt N2 gasflöde producerades överlapps lödfogar på både AlSi-belagt 22MnB5 (USIBOR® 1500P AS150) och vanligt 22MnB5. Kombinationen av material som undersöktes inkluderade två olika lödfolier samt två olika flusspastor tillsammans med olika värmecykler. Både enstegs lödcykler med lödning direkt vid austenittemperatur och tvåstegs lödcykler med lödning först vid en lägre temperatur följt av värmebehandling vid asutenittemperatur togs fram. Lödfogar utvärderades genom dragprov vilket också gjordes för att erhålla styrkan hos beläggningen på USIBOR® 1500P AS150 efter värmebehandling då lim användes för att skapa en överlappsfog. Vidhäftningsprovning utfördes för att bestämma adhesionsstyrkan av beläggningen på USBIOR® 1500P efter olika värmecykler. Svepelektronmikroskop (SEM) med Energi Dispersiv Spektroskopi (EDS) användes för att utvärdera mängden Fe diffusion från substrat till både beläggning och fog som följd av olika värmecyklar och för att bestämma faser berörande sprickpropagering i fogar. Med NiCr-baserad lödfolie producerades fogar mellan 22MnB5 stål med en håll tid för lödning om 10 minuter vid 950° C vilka hade medelvärde för skjuvstyrka på 20 MPa. Det visade sig att lödning ovanför tillsatsmaterialets liquidus temperatur i 5 minuter med en högre ugnstemperatur kunde reducera tiden i ugn med 16 minuter utan att påverka styrkan hos fogen, vilket gav en totaltid i ugn om 9 minuter. För fogar mellan USBIOR® 1500P substrat erhölls bäst resultat med en tvåstegs lödcykel. Lödning utfördes vid 593° C i 35 minuter med AlSi12 lödfolie och flusspasta rekommenderad för aluminium lödning. Proverna genomgick sedan en värmecykel över austenittemperatur i 4 minuter och hade medelvärde för skjuvstyrka på 5,4 MPa. Från EDS-analys framkom det att brott i fogar och i beläggning av USIBOR® 1500P AS150 sammanföll med den intermetalliska fasen Al5Fe2 och att Fe-diffusion från substrat var högre än i som levererat industriellt presshärdat USIBOR® 1500P AS150. Det visade sig från vidhäftningsprov att de värmecykler som använts i denna studie tydligt reducerade styrkan i beläggningen jämfört med prover från som levererat industriellt presshärdat USBIOR® 1500P AS150.

Abstract:
The automotive industry of today faces ever harder requirements from regulatory bodies to increase the fuel efficiency, reduce the carbon footprint and increase the safety of their vehicles. The problem is being tackled in different ways; one of them being the use of innovative materials to reduce the overall weight while improving the crash safety of the vehicle. One such material is 22MnB5, an ultra-high strength (UHS) boron-alloyed steel, capable of reaching tensile strength of 1900 MPa. The weldability is a vital factor for applying boron steel in an efficient way into a vehicle construction. Resistance spot welding (RSW) is, among the different welding methods, the primary joining methods used within the automotive industry. The main challenges with RSW of UHS boron steel is the narrow welding window and increased risk of expulsion compared to conventional automotive steel. The aim of this thesis was evaluating how the weldability of three-sheet UHS boron steel combinations could be improved by applying different innovative welding methods. The methods investigated where; three-pulsed welding, two-pulsed welding with force profile and using hollow-cone electrodes instead of regular electrodes. The different methods where evaluated with welding experiments and analysis of the nugget diameter, vicker hardness comparison and tensile strength test of welding nugget. The results from this thesis shows that the current window of three-sheet combinations with UHS boron steel can be significantly improved by using hollow-cone electrodes in RSW. The results also showed that the width of the current window varied depending on the depth of the hole in the electrode, a deeper hole improved the current window but also increased the oxide build-up. Applying a force profile with lowered electrode force during the welding sequence provided an improved process window compared to the constant electrode force when welding a three-sheet combination containing AlSi-coated boron steel. A three-pulse welding sequence performed better than the reference two-pulse welding schedule but still not good enough to meet VCC acceptance criteria.
Bilindustrin står idag inför allt hårdare krav från tillsynsmyndigheter förbättra bränsleeffektiviteten, minska koldioxidavtrycket och öka säkerheten på deras fordon. Problemet angrips från ett flertal olika vinklar. varav en ökad användning av innovativa material för att minska den totala vikten samtidigt som fordonets kraschsäkerhet bibehålls eller ens förbättras. Ett sådant material är 22MnB5, ett höghållfast (UHS) borstål, kapabelt att uppnå brottgränser på 1900 MPa.  Svetsbarheten är en vital faktor för att kunna applicera borstål på ett effektivt sätt i en fordonskonstruktion. Inom bilindustrin är motståndspunksvetsning (RSW) den dominanta svetsmetoden. De största utmaningarna med att punktsvetsa höghållfast AlSi-belagt borstål är det har ett generellt smalare svetsfönstren, samt den ökade risken för sprut under svetsprocessen, jämfört med konventionella stål. Målet med denna avhandling var att utvärdera hur svetsbarheten av tre-plåtskombinationer med höghållfast AlSi-belagt borstål kunde förbättras genom att applicera innovativa svetsmetoder. De utvärderade metoderna var; tre-pulsad svetsning, två-pulsad svetsning med applicerad kraftprofil, samt användning av ihåliga elektroder istället för vanliga elektroder. Metoderna utvärderades genom svetsexperiment och analys av svetslobens storlek, vicker hårdhets mätning samt brottgränsmätning av svetsloben. Resultaten från denna avhandling visar att svetsbarheten för tre-plåts kombinationer med UHS borstål kan förbättras avsevärt genom att använda ihåliga elektroder för punktsvetsning. Resultaten pekar också på att förbättringen beroende på hålets djup i elektroden. Ett djupare hål gav större förbättringar men ökade också uppbyggnaden av oxid och restmetall i elektroden.  Genom att applicera en kraftprofil, där elektrodkraften sänktes under svetsprocessen kunde svetsbarheten förbättras för två-puls svetsning, jämfört med att ha konstant elektrodkraft, vid svetsning av en tre-plåtskombination innehållande höghållfast AlSi-belagt borstål. En tre-puls svetssekvens utförde bättre än referenspulssvetsschemat men fortfarande inte tillräckligt bra för att uppfylla VCC-acceptkriterierna.

Metastable phases such as Al3Si can form in Al-Si composite films obtained by magnetron and ion-beam sputtering. In this work, we investigated the stability region of the Al3Si phase depending on the composition of the ion-beam AlxSi1-x films. Using X-ray diffraction and Ultrasoft X-ray Emission Spectroscopy, an ordered Al3Si solution with a primitive unit cell of the cubic system Pm3m and a lattice parameter of 4.085 Å was found in Al1-xSix ionbeam films. Studies have shown that the long-range order is quite resistant to changes in the elemental composition.

Abstract A commercial abradable coating AlSi-hBN was fabricated by atmospheric plasma spraying and was thermal aged at 450 °C in the atmospheric environment for 1000h. Thermal aging effect on coating abradability, hardness, bond strength and microstructure were evaluated. It was found that coating abradability increased obviously after 2h thermal aging and slightly decreased for extended thermal aging time. A sharp decrease in both coating hardness and bond strength were found after 2h thermal aging and a slow increase occurred with the extended aging time. Relationships between coating properties and microstructure were studied. Decomposition of organic binder and sintering of AlSi matrix metal generated by thermal aging were found to be reasons for coating properties changes.

Abstract:
Abstract Cu wires were bonded to AlSi (1%) pads, subsequently encapsulated and subjected to uHAST (un-biased Highly Accelerated Stress Test, 130 °C and 85% relative humidity). After the test, a pair of bonding interfaces associated with a failing contact resistance and a passing contact resistance were analyzed and compared, with transmission electron microscopy (TEM), electron diffraction, and energy-dispersive spectroscopy (EDS). The data suggested the corrosion rates were higher for the more Cu-rich Cu-Al intermetallics (IMC) in the failing sample. The corrosion was investigated with factors including electromotive force (EMF), self-passivation of Al, thickness and homogeneity of the Al-oxide on the IMC, ratio of the Cu-to-Al surface areas exposed to the electrolyte for an IMC taken into account. The preferential corrosion observed for the Cu-rich IMC is attributed to the high ratios of the surface areas of the cathode and anode that were exposed to the electrolyte, and the passivation oxide of Al with the lower homogeneity. The corrosion of the Cu-Al IMC is just a manifestation of the well-known phenomenon of dealloying. With the understanding of the corrosion mechanisms, prohibiting the formation of Cu-rich IMCs is expected be an approach to improve the corrosion resistance of the wire bonding.

Abstract:
Abstract Press hardening steel (PHS) applications predominately use 22MnB5 AlSi coated in the automotive industry. This material has a limited supply chain. Increasing the tensile strength and bendability of the PHS material will enable light-weighting while maintaining crash protection. In this paper, a novel PHS is introduced, and properties are compared to 22MnB5. The new Coating Free PHS (CFPHS) steel, 25MnCr, has increased carbon, with chromium and silicon additions for oxidation resistance. Its ultimate tensile strength (UTS) of 1.7 GPa with bending angle above 55° at 1.4mm thickness improves upon the 22MnB5 grade. This steel is not pre-coated, is oxidation resistant at high temperature, thus eliminating the need for AlSi or shot blasting post processing to maintain surface quality. Microstructural mechanisms used to enhance bendability and energy absorption are discussed for the novel steel. Performance evaluations such as: weldability, component level crush and intrusion testing and e-coat adhesion, are conducted on samples from industrial coils.
