Abstract:
Abstract It is of great practical value to complete the low-pressure casting of aluminum alloy impeller in the current development of low-pressure casting process. In the research, it is necessary to focus on factory realization and use low-pressure casting to produce aluminum alloy impellers, so that impeller castings with compact structure and meeting performance requirements can be obtained. Compared with other casting methods, low-pressure casting itself, as a precision casting method, can be cast on the metal solution with lower pressure in the application process. The castings can be filled and solidified under certain pressure, and the castings with compact structure can be obtained. In the research, Pro / Engineer is used to design the low-pressure casting mold for aluminum alloy impeller, and MAGMASOFT is used to carry out the filling and solidification process of aluminum alloy impeller. Through numerical simulation, we can accurately predict the defects of impeller castings, and optimize the mold scheme and pressure-time parameters according to the prediction results.

Abstract Establishing of wrought aluminum alloys casting to manufacture is now a global trend, for example due to lower production costs compare to forging or due to the ability to produce parts with thinner sections and more complex shapes. The aim of using these alloys in the foundry industry is in particular the creation of castings with higher mechanical properties than achieve castings made of standard casting aluminum alloys. Most often are cast wrought aluminum alloys of the 2xxx, 6xxx and 7xxx series. In the experiment, an alloy EN AW-2024 has been cast by modified technology of casting with crystallization under pressure. They were measured basic mechanical properties of the castings in the as-cast state and after heat treatment.

Abstract:
Foamed metals are promising materials with a unique combination of mechanical and operational properties: low specific gravity, low thermal conductivity, ability to absorb acoustic and electromagnetic vibrations, and the ability to deform under a constant load. Currently, the most used methods for producing foamed aluminum and foamed magnesium are methods based on mixing gas or porophore into molten aluminum and forming a porous structure during the solidification of the aluminum melt. An alternative to this technology is the formation of a porous structure through the use of soluble granules that pre-fill the mold and after impregnating the granules with molten metal and solidifying the castings, they are leached. The work aims to determine the influence of casting modes and the size of granules on the depth of impregnation of granular filling with metal melt during the formation of porous aluminum castings. The authors proposed the technique for calculating the depth of impregnation of granular filling when producing castings of porous non-ferrous metals based on the calculation of melt cooling when moving along the thin-walled channel. The calculations made it possible to determine the depth of impregnation and establish the allowable wall thickness of the casting of porous aluminum, depending on the size of the granules used, the speed of the melt in a form, the mold temperature, and the temperature of molten aluminum. The study identified that to increase the depth of impregnation and obtain porous aluminum castings with thinner walls, it is advisable to increase the diameter of the salt granules and not the temperature and hydrodynamic modes of casting. The authors carried out calculations and identified the influence of the casting regimes and the diameter of the granules on the depth of mold impregnation to obtain porous castings from promising magnesium alloys.

Abstract:
Abstract Porosity is one of the major defects in aluminum castings, which results is a decrease of a mechanical properties. Porosity in aluminum alloys is caused by solidification shrinkage and gas segregation. The final amount of porosity in aluminium castings is mostly influenced by several factors, as amount of hydrogen in molten aluminium alloy, cooling rate, melt temperature, mold material, or solidification interval. This article deals with effect of chemical composition on porosity in Al-Si aluminum alloys. For experiment was used Pure aluminum and four alloys: AlSi6Cu4, AlSi7Mg0, 3, AlSi9Cu1, AlSi10MgCu1.

Abstract:
Industrial semi-solid casting trials of aluminum A356 brake calipers were performed over five days with the CSIR-RCS and high-pressure die casting process cell. Consecutive visual passed castings were used as the measure of process stability, and common defects between trials were categorized. Short fill results are erratic and caused by unintended underdosing by the furnace or incomplete billet discharge at the delivery point in the shot sleeve. Cold shuts can be significantly reduced by adjusting the shot control profile. Surface finish defects include surface roughness and staining caused by lubricant burn off. Visual passed castings display none of the above-mentioned external defects. X-ray examination and pressure testing of heat-treated castings from the consecutive visual passed castings show improvement over the five days. These initial-stage industrialization efforts pave the way for process commercialization.

Abstract:
The production of die castings cast into a metal mold has in recent years achieved an expansive growth in the volume as well as the range of production and that is particularly in aviation and automobile industry. In the process of die casting the final quality of a cast is influenced by a great number of factors. The main factors of die casting are: pressing velocity, increase pressure, the melt temperature and the mold temperature. A primary criterion for achieving reliability, efficiency and quality of production is to ensure minimization of the castings defects occurrence in castings correct setting technological factors of die casting. The presented paper deals with the experimental assessment of the impact of increase pressure on the mechanical properties and homogeneity of a die cast.

Abstract:
Porosity is known to be one of the primary factors controlling fatigue life and total elongation in cast aluminum components. The thrust of this study is to examine pore nucleation and growth effects for predicting gas microporosity in A356 plates. In this work, a solidification model is used to quantify and evaluate the discrepancy between experimental data and porosity calculated with different approaches. The first approach considers hydrogen supersaturation based on the transport of dissolved hydrogen and Sievert?s law. The second approach uses the hydrogen supersaturation calculated in the first approach combined with a local solidification time. The third approach considers a new hydrogen technique based on the transport of inclusions through the liquid metal and mushy zone. Computer simulations were performed modeling aluminum plate castings.

Abstract:
In order to produce aluminum high performance castings, two main factors are essential: alloy and process. High performance castings are the result of the ideal equation of combination of these two factors. For this reason this PhD research project consisted in two main parts: 1. the first part has been developed together with Rheinfelden Alloys GmbH & Co. KG and consisted in an in deep analysis of aluminum alloys and their reinforcements mechanisms. 2. the second part has been developed in collaboration with TMB SpA and focused on the process and on process-related aspects affecting the quality of castings. A new way to introduce nanoparticles to reinforce aluminum-silicon alloys was found and an in deep analysis of the very high mechanical properties obtained has been carried out. This way, in comparison to the processes to produce Al-alloy based nanocomposites already present in literature, is very cheap and could be scaled-up to industrial scale. Nevertheless there are still some critical aspects in the use in industrial scale of these highly innovative nanocomposites and for this reason in the second part of the project has been studied how to produce high performance castings with already available alloys by optimizing the other factor of the equation: the process. Based on the defect classification made by Gariboldi, Bonollo and Parona in the “Handbook of defects in high pressure die castings” (2010) [1], several aspects regarding the process were taken in account and relevant results were obtained in order to get always high performance castings.
Al fine di produrre getti altoprestazionali in alluminio sono essenziali due fattori: la lega e il processo. Fusioni altoprestazionali sono il risultato dell’ideale equazione di combinazione di questi due fattori. Per questo motivo questo progetto di ricerca di dottorato consiste in due parti principali: 1. la prima parte è stata sviluppata in collaborazione con Rheinfelden Alloys GmbH & Co. KG e consiste in un’analisi approfondita delle leghe di alluminio e dei meccanismi del loro rafforzamento. 2. la seconda paste è stata sviluppata in collaborazione con TMB SpA ed è stata focalizzata sul processo e sugli aspetti del processo che possono influenzare la qualità dei getti. E’ stato sviluppato un nuovo metodo per l’introduzione di nanoparticelle al fine di rafforzare le leghe Alluminio-Silicio ed è stata svolta un’analisi approfondita delle notevoli proprietà meccaniche ottenute. Questo metodo, in confronto con gli altri processi per produrre nanocompositi a matrice lega di Alluminio presenti in letteratura, è molto economico e potrebbe essere sviluppato su scala industriale. Persistono tuttavia alcuni aspetti critici nell’utilizzo industriale di questi nanocompositi altamente innovativi e per questo motivo nella seconda parte del progetto è stato studiato come produrre getti altoprestazionali con leghe già disponibili ottimizzando l’altro fattore dell’equazione: il processo. Basandosi sulla classificazione dei difetti sviluppata da Gariboldi, Bonollo e Parona nel “Manuale di difettologia dei getti pressocolati” (2010) [1], sono stati presi in considerazione numerosi aspetti riguardanti il processo e sono stati ottenuti risultati rilevanti al fine di ottenere sempre getti altoprestazionali.

Abstract:
The reinforcement of an Al casting with ferrous inserts (hybrid systems) through a joining technique to utilize both Al alloys (lightness) and Fe-based alloys (stiffness) is of interest, especially in the transportation sector. This work focuses on different technological aspects of cast joining of cast iron to an Al alloy using an intermediate material (or coating). The experimental set up consisted of preparing the insert surface followed by coating the insert, and then, immersing it into an Al melt, and allowing the system to cool down to room temperature. The effects of flux treatment, decarburization, and the coating application, as well as the immersion time in the Al melt on the Al-Fe joint quality were investigated. The microstructure evolution of the reaction layer forming at the insert-coating interface was determined as a function of the coating time and the coating composition, and their effects on the joint properties were evaluated. The relationship between the microstructure and microhardness of the joint zone was established. Decarburization, flux treatment, suitable coating, and optimizing the process parameters improved the joint properties. Combination of "McGill 2" coating alloy and 1 min immersion time (in the Al melt) resulted in the formation of an Al-Fe joint with optimized characteristics. The results showed that the cast joining could be used to strengthen the Al castings and improve their performance.
Le renfort des pièces coulées en aluminium par l'assemblage d'insertions ferreuses (systèmes hybrides) permet de combiner la légèreté de l'aluminium avec la rigidité des alliages à base de fer. Cette technique présente donc un grand intérêt pour plusieurs applications, spécialement dans le secteur des transports. Ce projet porte sur les différents aspects technologiques de la coulée de pièces avec joint aluminium-fonte auquel est ajouté une couche intermédiaire (ou revêtement). La procédure expérimentale a consisté à préparer la surface des insertions, à appliquer le revêtement, puis immerger la pièce dans un bain d'aluminium liquide, pour finalement refroidir le système jusqu'à la température de la pièce. Les effets du traitement par flux, de la décarburisation, et des paramètres de revêtement ainsi que la durée d'immersion dans l'aluminium liquide sur la qualité du joint aluminium-fonte ont été étudiés. L'évolution de la microstructure par la formation d'une zone de réaction à l'interface de l'insertion de réaction et zone du revêtement a été déterminée en fonction de la composition du revêtement er du temps d'immersion dans le revêtement liquide, et leurs effets sur les propriétés du joint été évalués. La corrélation entre la microstructure et la microdureté du joint ont a été établie. La décarburisation, le traitement par flux, l'utilisation d'un revêtement approprié et l'optimisation des paramètres du procédé améliorent significativement les propriétés du joint. L'utilisation du revêtement "McGill 2" avec un temps d'immersion dans le bain d'aluminium d'une minute permet la formation d'un joint Al-Fe avec des caractéristiques morphologiques, d'épaisseur, de microdureté et de composition optimisées. Les résultats montrent que l'insertion de pièces formant un joint peut être utilisée pour renforcer les pièces d'aluminium et

Full text
Abstract:
The permanent mold casting process is a relatively popular and effective casting technology that can produce near-net-shape aluminum components with integrity, particularly for the automotive and aerospace industries. It is well recognized by the casting industry that it is essential to control the cooling of permanent mold castings in order to improve the quality of the castings, so there is a considerable incentive to develop a more effective method of mold cooling to control the temperature distribution of the mold and the casting. The current technologies for controlled cooling are air or water cooling passages and chill inserts. Each of these cooling methods presents certain disadvantages, and none offer optimum cooling control. Based on these considerations, a novel, effective and controllable water-based heat pipe has been successfully developed to be used as a new method of permanent mold cooling where high heat fluxes are normally encountered. Heat pipes featuring this design have been incorporated in an experimental permanent mold made of HI3 tool steel that contains three symmetric steps. Computer modeling for the permanent mold casting process has been accomplished to predict the effect and potential of heat pipe cooling for permanent mold casting. Castings of A3 56 alloy have been produced by this permanent mold. The effects of heat pipe cooling on permanent mold castings have been evaluated by analyzing the temperature distribution of the mold and the casting, as well as by measuring the dendrite arm spacing and shrinkage distribution of the castings. The effect of heat pipe cooling on the mold solidification time of castings of A356 alloy with different coating types was also studied. Industrial trials have been carried out to evaluate this new cooling technology on an industrial scale casting machine. Because the space around the mold installed on a low pressure die casting machine is very limited, it is often very difficult to install the heat pipe in the specific desired location in the mold. A new version flexible heat pipe cooling system has been developed for the industrial casting process. Preliminary and industrial tests of the heat pipe cooling system have been performed. The effects of heat pipe cooling, as well as the effects of using traditional water and air cooling on the low pressure die casting were studied. Data on the cooling rates obtained by heat pipes, as well as some microstructures and measurements of the dendrite arm spacing are presented in this thesis. Modeling and experimental results have shown that the water based heat pipe can provide high cooling rates in casting processes. The dendrite arm spacing (DAS) of A356 alloy is refined considerably by the heat pipes, and changes in the shrinkage pattern are provided by the dramatic changes in the heat flow patterns.

Abstract:
Abstract Commercial software packages enable the thermal environment of shaped castings to be determined provided the boundary conditions are well understood. Criteria functions (CF’s) based on the thermal environment provide a means for estimating shrinkage porosity within a casting. However, the CF’s do not account for gas driven porosity forming within the casting. This paper reviews the CF’s and additional approaches to account for hydrogen evolution in aluminum-copper and aluminum-silicon alloys.

Abstract:
"As a result of the increasing demand to minimize the weight of automotive vehicles as well as reducing particle emissions, Al-matrix composite (Al-MC) is gaining interest as a potential material for manufacturing automobile brake discs because of its good corrosion property, high thermal conductivity and higher wear resistance when compared to the traditional grey cast-iron brake disc material. However, to mass-produce Al-MC brake discs, an efficient and robust manufacturing process is required. The squeeze casting technique is considered as one of the economical casting processes by which Al-MC material can be shaped into readily usable components. This process is attractive because squeezed cast products exhibit better mechanical properties due to the presence of fewer common defects such as porosity and shrinkage cavities, and the segregation of the reinforcing material is eliminated. To efficiently use squeeze casting industrially, its processing parameters such as squeeze pressure, pouring temperature, mould die temperature and melt flow speed must be optimized to ensure sound castings. When a newly designed component is to be produced by squeeze casting, the casting parameters must be optimized for such a component. This optimization is conventionally performed through experimental trials which consume a lot of material resources and time. Nowadays, the application of computer simulation to model casting processes has enabled foundry engineers to shorten casting development time, maximize material usage, establish a robust process window by optimizing casting process parameters, reduce quality costs by preventing metal casting defects resulting from turbulence and other inclusions, predict and prevent defects in castings, and hence ensures quality castings and reduces product manufacturing costs. This paper discusses how a casting simulation program could help to ensure a high-quality casting of Al-MC brake discs by investigating the influence of squeeze casting parameters on the possibility to minimize casting defects through parameters optimization. The 3D mechanical CAD software (Inventor LT) program was used to construct the 3D model of the brake disc and the forming tool, and the step files were imported into the NOVACAST software to simulate the casting and solidification processes. Further, two-parameter settings from the simulation results were implemented experimentally to produce squeeze cast Al-MC brake discs. The cast discs were examined and compared with the simulation results to check the adequacy of the simulation in predicting the quality of the brake disc. "
