This book was released on 2015-10-30 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: The design of aeronautical alloys requires the use of these particular alloys for their strength and ductility. These properties can be further enhanced by controlling the added alloying elements as well as the heat treatment parameters. The objective of the present work was to determine the effect of the interactions between element additions and heat treatment on the alloy microstructure and mechanical properties. The present study was carried out to investigate both the formability and mechanical properties of 6xxx alloy series. The slabs (7 x 11 x 1.5 cm each) were machined and homogenized for 10 h at 520 C, followed by air cooling. The results show that a -iron phase displays low formability and hinders deformation of the grains during cold rolling and leads to premature cracking. The cold rolled structure contains elongated grains with broken -Al5FeSi platelet fragments. In the Mn-containing alloy, the -iron phase is more easily deformable while addition of Sr does not improve the alloy behavior. With beryllium additions, the iron intermetallics precipitate in the form of small, globular -Al8Fe2SiBe script particles, in the interdendritic regions."

Download or read book Mixed mode Model for Studying Microstructural Evolution of Precipitates Inside Aluminum Alloys written by Tohid Naseri and published by . This book was released on 2020 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aluminum is one of the most used non-ferrous metal in the world with an enormous range of applications from simple kitchenware to advanced spacecraft. In applications where high mechanical properties are needed, like in the car industry, it is strongly required to improve the mechanical properties. As the final distribution of precipitates plays a crucial role in mechanical properties of these alloys, a better understanding of the microstructural evolution and kinetics of precipitation can help noticeably the design of the heat treatment process of aluminum alloys. However, due to the size and morphology of the precipitates, experimental studies of the precipitation required advanced characterization methods like transmission electron microscopy which is not an industrially favorable technique since it is costly and required a lot of technical expertise. Numerical investigation can be a desirable tool to model the evolution of the precipitates and the corresponding mechanical properties. This study presents a kinetic model of precipitation. Unlike many studies that mainly focus on the diffusion and surface energy, we consider interfacial mobility as an effective variable in a mixed-mode model. This variable not only provides us the possibility to study the precipitates’ evolution in multicomponent alloys but also can boost the calculation performance. Moreover, the other superiority of this model is the possibility of working with complex multiphase industrial Al alloys by considering the growth and the dissolution of different types of precipitates simultaneously.

This book was released on 2013 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: The process of heat treatment is the method by which metals are heated and cooled in a series of specific operations that never allow the metal to reach the molten state. The purpose of the heat treatment is to cause desire changes in the metallurgical structure and thus in the properties of metal parts. The aim of this research is to study the influence of heat treatment and natural aging mechanism on the microstructure and mechanical properties of aluminum alloy 6061. The aluminum alloy 6061 sample heat treated using T4 method which is heat treated at 550°C, 575°C and 600°C and then naturally aged at ambient environment for 3 hours. After heat treated process, the effects were investigated in terms of microstructure using metallurgical analysis and mechanical properties by tensile tests and hardness test. Tensile tests show that the yield stress and UTS have high value when heat treated at 600°C where 103.28693 MPa and 195.246895 MPa meanwhile the Young modulus heat treated at 550°C have high value; 84417.95106 MPa. For heat treatment specimens, the high VHN is specimen's heat treated at 600°C which have value 85.7 and the lower VHN value is specimen's heat treated at 550°C with value 57.5. The heat treatment process result soft aluminum alloy 6061. Lastly for microstructure observation, different microstructure appear within different heat treatment temperature. From the data and result that already determined, it achieved the objectives and scope of this research.

This book was released on 2008 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Pure aluminium has a high thermal conductivity, but as alloying elements are added the thermal conductivity decreases. How much it occurs depends on the alloying elements and whether they are present in solid solution, as small precipitates or larger particles. The present work studies the influence of Cu and Mg additions on the thermal conductivity of Sr-modified as-cast and T6-heat treated Al-Si alloys for a wide range of temperatures (30-400 oC). An unmodified Al-Si alloy with no additions was analysed as well so as to investigate the influence of the modification with Sr. Three properties were determined to calculate the thermal conductivity: thermal diffusivity, specific heat and density. Thermal diffusivity measurements were carried out by means of a Laser Flash device. Regarding the Sr-modified Al-Si alloys, the highest thermal conductivity corresponds to the alloy without the addition of other elements in both as-cast and T6 condition. The alloys containing Cu have in general a lower thermal conductivity than the alloys with solely Mg. The presence of Mg has an overall beneficial effect in as-cast conditions for an alloy containing Cu. In contrast, this addition becomes detrimental for a copper-bearing heat-treated alloy in most of the temperature range. With regard to the Sr-modification outcome, it was found that enhances thermal conductivity in as-cast alloys. Nevertheless, its influence after the heat treatment requires a further study. The thermal conductivity increases normally with the temperature and when the T6 heat treatment is applied. This increment is attributable to the purer aluminium matrix obtained as the precipitates form, grow and coarsen.

Available in PDF, EPUB and Kindle. Book excerpt: Most of the powder metallurgical research on particulate aluminum alloys has been focused on optimizing composition. However, the role of process parameters on sinterability of prealloyed powders still remains to be critically evaluated. First part of the study logically evaluates the effect of sintering atmosphere (nitrogen, argon and vacuum) and temperature on sintered density, electrical, electrochemical and mechanical properties of Al-Cu-Mg, Al-Mg-Si and Al-Zn-Mg alloys. The effect of heat treatment (T4, T6 and T8 tempers) on microstructure and properties was also investigated. In an attempt to make the process less energy intensive and control the grain growth at higher temperature, in second part of the study, higher heating rates were implemented using multimode microwave (2.45 GHz and 6kW) furnace. Microstructural changes and properties were compared between microwave and conventional heated compacts. This book should help to shed some knowledge on new processing technologies, interaction of microwave with conductive materials and especially useful to researchers, professionals and students working in the field of aluminum powder metallurgy and microwave processing.
