Full textResumo: Os aços microligados são materiais já tradicionais e muito versáteis por suas propriedades mecânicas superiores, sendo sua evolução diretamente ligada com a otimização da composição química e do processamento termomecânico. É um tipo de aço que apresenta uma microestrutura refinada, alta resistência mecânica, boa usinabilidade e soldabilidade e tem substituído aços comuns por atingir essas propriedades mecânicas a partir de processos de fabricação mais baratos. Os aços estudados são comerciais, apresentam limite de escoamento entre 419 MPa e 646 MPa e grãos ferríticos finos com tamanhos inferiores a 3,70 μm. Neste trabalho são investigadas chapas industriais produzidas por laminação controlada, visando analisar a correlação entre a microestrutura ferrítico-perlítica e as propriedades mecânicas encontradas nas diferentes secções longitudinal, transversal e normal da chapa laminada. As diferenças entre as diferentes secções não são bem exploradas atualmente, então este estudo contribui para uma melhor compreensão da anisotropia introduzida pelo processamento termomecânico industrial. Foram feitas correlações entre as propriedades, confirmando a existência de diferenças estatisticamente significativas entre as secções, constatando que esses aços podem apresentar variações em suas propriedades de acordo com a secção de análise adotada. Foi confirmada a correlação de Hall-Petch nos aços estudados, e a influência dos mecanismos de endurecimento foi avaliada para estes materiais.
Abstract: Microalloyed steels are traditional materials and very versatile due to their superior mechanical properties, being its evolution directly linked with an optimization of the chemical composition and the thermomechanical processing. It is a type of steel that has a fine microstructure, high mechanical strength, good machinability and weldability, and has substituted common steels for achieving these mechanical properties with a cheaper manufacturing process. The studied steels are commercial and have yield strength between 419 MPa and 646 MPa and fine ferritic grains with size smaller than 3.70 μm. In this work are investigated industrial plates produced by controlled lamination, aiming to analyze the correlations between ferrit-perlitic microstructure and the mechanical properties found in the different sections of the hot rolled plate (longitudinal, transverse and normal). The differences between the different sections are not well explored, so this study contributes to a better understanding of the anisotropy introduced by industrial thermomechanical processing. Correlations were made between the properties, confirming the existence of significant differences between the different sections, finding that these steels may show different properties according to the section of analysis adopted. The Hall-Petch correlation was confirmed in the studied steels, and the influence of the hardening mechanisms was also evaluated.

Full textSuperduplex stainless steels (SDSS) may be defined as a family of steels having a two-phase ferritic-austenitic microstructure and the good mechanical properties and high corrosion resistance of this alloy are attributed to this microestrutural balance. These excellent qualities attribute to SDSS great employability in the oil sector, where manufacturing and equipment maintenance are performed by welding, which if not executed properly, can have a negative effect on the metallurgical properties and this problem becomes more critical in multipass welding due to repeated thermal cycles. Among the several welding processes employed in the welding of SDSS, fell to this work was to evaluate the FCAW process in multipass welding joints of SDSS UNS S32750, regarding the selection of appropriate welding parameters and the influence of these parameters on microstructural transformations, mechanical properties and corrosion resistance of welded joints. Then, this work was divided into three steps: Stage 1 was the characterization of the base metal in as-received condition. In Stage 2, weldings were accomplished using a bead on plate (BOP) technique to determine the control factors and their levels to be used in the subsequent stage, in which an experimental design was conducted by Taguchi method with Alloy, Stick out, Shielding gas, welding gun orientation, Arc oscillation, Energy technique and Heat input used as control factors and quality characteristics were evaluated the ratio R/L, bead penetration, ferrite content and inclusions content and microhardness. Finally, in Stage 3 were performed multipass welding in joints and afterwards was executed: A microstructural characterization in three regions of Fusion Zone (Root, Filler and Cap) and Heat Affected Zone by Optical Microscopy (OM) and Scanning Electron Microscopy (SEM) and Energy Dispersive X-ray Spectroscopy (EDS) and were also performed a measurement of the ferrite content; measurement of inclusions content; microhardness tests and Critical Temperature Pitting (CPT) tests according to ASTM G150. The results showed, ferrite contents ranging from 44% and 54.9% and their highest values were observed when employed the alloy 2507, heat input of 1.6 kJ/mm and pulsed current. The lowest inclusions contents were obtained by using of shielding gas with the mixture of 96%Ar + 4%CO2 (Stage 2) and heat input of 1,6kJ/mm (Stage 3). The microhardness values in FZ of joints were not affected significantly by any of the control factors. Already, the results of CPT tests showed that pits nucleated preferentially within α, at α/γ grain boundaries and at interfaces areas between large diameter inclusions and the metallic matrix and propagated predominantly into α phase. The CPT values ranging from 47 ÂC to 78 ÂC, with highest were obtained for the alloy 2507, heat input of 1.6 kJ/mm and continuous current into Root region and for the alloy 2507, heat input of 1.6 kJ/mm and the pulsed current in Filler and Cap regions. From the three regions of FZs, the Root showed the best results with no defects, satisfactory ferrite contents, lowest inclusions contents and highest CPT values.
Os aÃos inoxidÃveis superduplex (AISDs) possuem uma microestrutura bifÃsica constituÃda por ferrita (α) e austenita (γ) e quando devidamente balanceadas conferem ao material, boas propriedades mecÃnicas e elevada resistÃncia à corrosÃo. Qualidades que atribuem aos AISDs grande empregabilidade no setor petrolÃfero, onde a fabricaÃÃo e manutenÃÃo de equipamentos sÃo realizadas por soldagem e se executada inadequadamente, pode afetar negativamente as propriedades destes aÃos, o que se torna mais crÃtico quando hà a imposiÃÃo de inÃmeros ciclos tÃrmicos durante uma soldagem multipasse. Dentre os inÃmeros processos de soldagem utilizados na soldagem dos AISDS, coube a este trabalho avaliar o processo arame tubular na soldagem multipasse em juntas do AISD UNS S32750, levando em consideraÃÃo a seleÃÃo dos parÃmetros de soldagem adequados, bem como a influÃncia destes parÃmetros nas alteraÃÃes microestruturais, microdureza e resistÃncia à corrosÃo das juntas soldadas. Desta forma, dividiu-se este trabalho em trÃs etapas: A Etapa 1 consistiu na caracterizaÃÃo do metal de base na condiÃÃo como recebido. Jà na Etapa 2 foram realizadas soldagens por simples deposiÃÃo para selecionar os fatores de controle e seus nÃveis a serem utilizados na etapa posterior, e o planejamento experimental foi realizado pelo mÃtodo Taguchi com a Liga, GÃs, DBCP, TÃcnica da Tocha, Tecimento, TÃcnica de Energia e Energia foram utilizados como fatores de controle e como variÃveis de resposta escolheu-se a razÃo R/L, a penetraÃÃo, a fraÃÃo de ferrita, a fraÃÃo das inclusÃes e a microdureza. E por fim, na Etapa 3 foram realizadas soldagens multipasse em juntas e posteriormente efetuou-se: uma caracterizaÃÃo microestrutural em trÃs regiÃes da Zona Fundida (Raiz, Enchimento e Acabamento) e Zona Afetada pelo Calor atravÃs de Microscopia Ãtica (MO) e Microscopia EletrÃnica de Varredura (MEV) e Espectroscopia de Energia Dispersiva de Raios X (EDS); quantificaÃÃo da fraÃÃo de ferrita; quantificaÃÃo da fraÃÃo das inclusÃes; ensaios de microdureza e uma avaliaÃÃo da resistÃncia à corrosÃo por pites atravÃs dos ensaios de temperatura crÃtica de pite (CPT) seguindo a norma ASTM G150. Como resultados, obteve-se fraÃÃes de ferrita entre 44% e 54,9% com seus maiores valores observados quando utilizou-se a liga 2507, a energia de 1,6 kJ/mm e a corrente contÃnua pulsada. As menores fraÃÃes das inclusÃes foram obtidas pela utilizaÃÃo do gÃs de proteÃÃo com 96%Ar + 4%CO2 (Etapa 2) e da energia de 1,6kJ/mm (Etapa 3). As microdurezas na ZF das juntas nÃo apresentaram diferenÃas significativas. Jà os ensaios de CPT revelaram que os pites nuclearam preferencialmente no interior da α, nos contornos α/γ e nas interfaces entre inclusÃes de grande diÃmetro e a matriz metÃlica, propagando-se exclusivamente atravÃs da α. Os valores de CPT apresentaram uma faixa de 47ÂC à 78ÂC, com os maiores valores obtidos para a liga 2507, a energia de 1,6 kJ/mm e a corrente contÃnua constante na regiÃo da Raiz e nas regiÃes do Enchimento e Acabamento ao utilizar-se a liga 2507, a energia de 1,6 kJ/mm e a corrente contÃnua pulsada. Dentre as trÃs regiÃes das ZFs, a Raiz apresentou os melhores resultados com ausÃncia de defeitos, fraÃÃes de ferrita satisfatÃrias, menores fraÃÃes das inclusÃes e maiores valores de CPT.

Full textDetta projekt undersöker möjligheten att använda trycksvetsningsmetoden friktionssvetsning som sammanfogningsmetod för det kvävelegerade pulvermetallurgiskt framställda stålet Uddeholm Vanax SuperClean. Vanax SuperClean kan inte svetsas med smältsvetsmetoder där grundmaterialet smälter, på grund av kvävgasbildning som resulterar i undermåliga svetsfogar. Kostnaden för materialet motiverar användandet av Vanax SuperClean för kritiska delar i applikationer, kombinerat med ett mindre kostsamt material till övriga delar, vilket föranleder undersökning av alternativa sammanfogningsmetoder. Vanax SuperClean friktionssvetsas mot sig själv, såväl som mot Uddeholmsstålen Stavax ESR och UHB 11. Prov tas fram för ett antal undersökningar. Mikrostruktur undersöks med mikroskopi, mikrohårdhetsprovning utförs enligt Vickersprincipen, restaustenitnivåer mäts med röntgendiffraktion och dragprovning utförs. Lyckade svetsfogar fås i alla undersökta prover, vilket visar att svetsmetoden är lämplig för Vanax SuperClean och att varken förvärmning eller långsamt svalnande av arbetsstycken krävs. Möjligheten att använda friktionsomrörningssvetsning som sammanfogningsmetod för Vanax SuperClean diskuteras.

Os aÃos inoxidÃveis duplex possuem boas propriedades mecÃnicas e excelente resistÃncia à corrosÃo, aumentando seu uso em ambientes agressivos. Estas caracterÃsticas os fazem muito utilizados principalmente na indÃstria quÃmica e petroquÃmica. Geralmente, a fabricaÃÃo e reparo destes equipamentos envolvem operaÃÃes de soldagem, sendo que à muito importante avaliar a influÃncia dos parÃmetros de soldagem multipasse no balanceamento de fases, na microestrutura e microdureza. Primeiramente, foram realizadas soldagens em aÃo ASTM A516 Gr. 60 com eletrodo revestido AWS 2209-17, empregando diversas energias, variando a velocidade e corrente de soldagem. Foi feita a caracterizaÃÃo microestrutural atravÃs de microscopia Ãptica, quantificaÃÃo do teor de ferrita utilizando ferritoscÃpio e ensaio de microdureza para avaliar o metal de solda. Posteriormente, foram selecionadas as melhores condiÃÃes da etapa anterior para soldagem do aÃo inoxidÃvel duplex UNS S31803 para avaliar o efeito da energia de soldagem no balanceamento de fases, na microestrutura e microdureza no metal de solda e ZAC. Na Ãltima etapa foram realizadas soldagens em juntas de aÃo duplex, de modo a avaliar o efeito da energia de soldagem e restriÃÃo da junta no balanceamento de fases, microestrutura, microdureza e tenacidade do metal de solda e da ZAC. Foi verificada a influÃncia da energia de soldagem no teor de ferrita, possuindo comportamentos diferentes de acordo com os parÃmetros de soldagem. As microestruturas bÃsicas da austenita formada foram alotrimÃrfica, WidmanstÃtten e intragranular. Nas regiÃes com sobreposiÃÃo de passe houve maior quantidade de austenita no metal de solda e microestrutura mais refinada na ZAC. Foi observado que quanto maior a velocidade de soldagem, maior a quantidade de WidmanstÃtten. De forma geral, foi observado menor nÃvel de microdureza no metal de solda, principalmente nas condiÃÃes com maior quantidade de austenita WidmanstÃtten. A restriÃÃo da junta soldada influenciou no balanceamento de fases e na tenacidade da ZAC. NÃo houve efeito da energia de soldagem na tenacidade do metal de solda, possuindo nÃveis menores em relaÃÃo ao material como recebido
Duplex stainless steels show good mechanical properties and excellent corrosion resistance. These qualities are increasing their use in aggressive environments. Thus, these characteristics make them very used in chemical and petrochemical, mainly. Generally, the manufacture and repair of any industrial equipment involve welding operations, even though it is very important to evaluate the influence of multipass welding parameters in phase balances, microstructure and microhardness. Firstly, the shielded metal arc welding in steel ASTN A516 Gr. 60 with electrode AWS 2209-17 had been carried through with many energies, varying welding speed and current. Microstructural characterization by optic microscopy, quantification of ferrite content using ferritscope and microhardness test has being performed to evaluate the weld metal. After that, the best conditions of the last stage for welding of duplex stainless steel UNS S31803 had been chosen to evaluate the effect of the welding energy in phase balances, microstructure, and microhardness in the weld metal and HAZ. In the last stage, the weldings in joint of duplex steel had been carried through, in order to evaluate the effect of the welding energy and restriction of joint in phase balances, microstructure, microhardness and toughness of the weld metal and HAZ. The influence of the welding energy in the ferrite content was checked, although the behavior was different according to variation of the welding parameters. The basic microstructures of formed austenitic were allotriomoph, WidmanstÃtten and intragranular. Regions with pass overlapping presented greater amount of austenite in the weld metal and microstructure more refined in the HAZ. It was observed that increasing welding speed, greater is the amount of WidmanstÃtten austenite. In general, the increase of the amount of WidmanstÃtten austenite decreases level of microhardness in the weld metal. The restriction of the welded joint influenced in phase balances and toughness of the HAZ. There was not effect of the welding energy on toughness of the weld metal and this region occurred higher levels in relation to material as received

Full textTiivistelmä Austeniitin muokkauksen vaikutusta mikrorakenteeseen ja mekaanisiin ominaisuuksiin, erityisesti särmättävyyteen, tutkittiin suorasammutetuilla martensiittis-bainiittisilla suurlujuusnauhateräksillä. Kuumavalssauksen lopetuslämpötilan lasku kasvatti austeniitin kokonaisreduktiota ei-rekristallisaatioalueella. Mikroseostus niobilla kasvatti myös kokonaisreduktiota, kun taasen muutokset C-, Mn- ja Mo -pitoisuuksissa eivät vaikuttaneet yhtä voimakkaasti. Valssauksen lopetuslämpötilan lasku kasvatti pehmeämpien mikrorakenteiden, kuten ferriitin ja granulaarisen bainiitin, määrää nauhan pintakerroksessa. Terästen keskilinjan mikrorakenteet koostuivat pääasiassa itsepäässeestä martensiitista sekä pienestä määrästä bainiittia. Kokonaisreduktion kasvu voimisti ~{554}<225>α - ja ~{112}<110>α -tekstuurikomponentteja keskilinjalla sekä ~{112}<111>α- ja ~{110}<112>α - {110}<111>α -komponentteja nauhan pintakerroksessa. Särmättävyys oli huonompi särmän ollessa poikittain valssaussuuntaan nähden kuin pitkittäin. Pintakerroksen kovuuden kasvu heikensi särmättävyyttä. Pintakerroksen voimakas ~{112}<111>α -leikkaustekstuuri, yläbainiitin ja MA-saarekkeiden läsnä ollessa, osoittautui haitalliseksi särmän ollessa poikittain valssaussuuntaan nähden. Särmättävyyden anisotrooppisuus voidaan selittää geometrisella pehmenemisellä rakeissa, joissa kyseinen tekstuurikomponentti on voimakas. Leikkausmyötymän paikallistuminen estyy, kun pinnassa on riittävän paksu hyvän muokkauslujittumiskyvyn omaava kerros, mikä sisältää esim. ferriittiä ja granulaarista bainiittia, mutta ei ferriittiä ja yläbainiittia. Särmättävyys osoittautui pysyvän hyvänä huolimatta haitallisesta tekstuurikomponentista, kun pehmeä pintakerros ulottui noin 5 % syvyydelle levyn paksuudesta. Edellä mainitut mikrorakenteet ja hyvä särmättävyys voidaan saavuttaa suorasammutetuilla yli 900 MPa myötölujuuden nauhateräksillä yhdessä hyvän iskusitkeyden kanssa, kunhan valitaan sopiva kemiallisen koostumuksen ja valmistusparametrien yhdistelmä sekä kiinnitetään huomiota teräksen sulkeumapuhtauteen

This work investigates the magnetic properties (hysteresis loop and Barkhausen noise) in some steels (ABNT 1045, 1050 and 1548) whose surfaces had been hardened by induction. The goal was to develop a non-destructive test procedure to determine the thickness of the hardened layer, thus avoiding the need to perform (destructive) measurements of the microhardness. Measurements of the magnetic susceptibility showed a peak (ferrite) around 800 A / m and other (martensite) at around 3500 A / m. Therefore, a correlation was sought between the peak amplitude of ferrite with the thickness of hard layer on the surface. For this purpose sensors were developed to measure Barkhausen noise as well as a filter for signal processing. It was possible to correlate measurements of microhardness with some features observed in magnetic measurements, for example, the amplitude of the Barkhausen noise and magnetic field of peak Barkhausen signal. Thus, a relationship was found between the amplitude of the Barkhausen noise and the thickness of the surface layer. It would be desirable to supplement these with other measurements and suggestions for further work are detailed.
