Investigation of the T4 and T6 Heat Treatment Cycles of Semi-Solid Processed Aluminium Alloy A356
The heat treatment cycles that are currently applied to semi-solid processed components are mostly those that are in use for dendritic casting alloys. These heat treatments are not necessarily the optimum treatments. It is shown that a decrease of the solution treatment time at 540 o C from 6 hours to 1 hour does not alter the T4 or T6 tensile properties of the SSM processed A356 alloy. Slightl...
متن کاملThe T6 Heat Treatment of Semi-Solid Metal Processed Alloy A356
A solution treatment of 1 hour at 540 o C provided the best results for rheocast alloy A356-T6. Natural aging has a significant influence on the subsequent artificial aging response of the alloy. Arrhenius-type equations were derived to predict the time-to-peak hardness as a function of artificial aging temperature.
متن کاملEffect of Reheating to the Semisolid State on the Microstructure of the A356 Aluminum Alloy Produced by Ultrasonic Melt-Treatment
The effect of reheating to the semisolid state (soaking treatment) on the microstructure evolution of the A356 aluminum alloy prepared by ultrasonic melt treatment was studied in this paper. The results showed that in general the longer the soaking process the larger and the more round the grains obtained. Higher roundness occurs at shorter soaking times in the fine-grained ascast samples, and ...
متن کاملPorosity Prediction in Aluminum A356 Alloy Castings
A comprehensive methodology that takes into account alloy solidification, shrinkage-driven interdendritic fluid flow, hydrogen precipitation, and porosity evolution has been developed for the prediction of microporosity fraction in aluminum A356 alloy castings. The mathematical models presented are implemented in a computational framework consistent with those of commercial casting codes, allow...
متن کاملSoldering of Aluminum Matrix Composites Sicp/a356 and Kovar Alloy
Article history: Received 28.3.2013 Received in revised form 26.4.2013 Accepted 29.4.2013 Aluminum matrix composites containing 55% SiC particle reinforcing phase/SiC reinforcement phase particle and Kovar alloy 4J29 were chosen as the base metals. After nickel plating on the surface of SiCp/Al, two kinds of materials were soldered together by using Zn-Cd-Ag-Cu as the filler metal and ZnCl2 as ...
