Effect of Solution Treatment Temperature on Microstructure and Mechanical Properties of A356 Alloy

Over the years, aluminum content in a vehicle part is increasing due to the needs to reduce weight as well as increase fuel efficiency. Most of the cast product in a vehicle part is mostly cast from A356 alloy. It is used because A356 alloy posses’excellent characteristics over other type of alloy s...
