Effects of Melt Cooling Rate on the Microstructure and Tensile Properties of A356 Aluminum Alloy Modified with Yttrium AITranslate
Abstract AITranslate
. A356 aluminum alloys modified with yttrium were prepared at different melt cooling rates, and then their microstructure and tensile properties were studied. The results show that with melt cooling rate decreasing,a-Al primary crystal has bigger grains and irregular distribution,and its secondary dendrite arm spacing increases. Meanwhile,the microstructure of eutectic silicon is transformed from granule or fibre to flake or needle, and the tensile properties of the alloy significantly decrease resulting in the transition from ductile fracture to brittle fracture. The rare earth element of yttrium is sensitive to the melt cooling rate. Only at relatively high melt cooling rate, yttrium can promote eutectic silicon growing up according to modification morphology.
