Impact Properties of A356-T6 Alloys
The Charpy impact energy of A356 alloys has been measured. Instrumented Charpy impact tests have been conducted at 25, 100, 150, and 200 ~ The Charpy specimens were machined from plate castings or tapered cylindrical castings. The plates were produced in sand molds, and tapered cylinders were produced in water-cooled copper molds. Both unmodified and strontium-modified castings were tested. The...
متن کاملInvestigation 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 کاملPorosity Control and Fatigue Behavior in A356-T61 Aluminum Alloy
Much work has been done, in recent years, to characterize the factors that cause porosity in aluminum castings, and to analyze the impact of porosity or microstructural parameters on fatigue life. What has yet to be done is systematically separate out the effects of dendrite arm spacing and largest pore size from each other, and from the underlying chemical and process parameters that influence...
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 کاملIonic Inhibition of Environmental Fatigue Crack Growth in 7075-t6
The objective of this study is to quantify and understand the effectiveness of a hexavalent chrome replacement ion to inhibit environmentally assisted fatigue crack propagation (EFCP) in high strength aluminum alloys. Because of dynamic-cyclic stress (or strain) loading, fatigue degradation occurs at stress levels considerably lower than the tensile or yield strength; degradation is exacerbated...
