Research on Semi-Solid Y112 Alloy Fabricated by Mechanical Stirring

Abstract:

Effects of different technological parameters such as stirring temperature, stirring speed and stirring time on the microstructure of semi-solid Y112 alloy were investigated using a self-developed mechanical stirring device in this paper. The results show that the higher of stirring temperature and stirring speed, the finer and more homogeneous the spherical grains, the higher the tensile strength and elongation. If the temperature is too high, the solid grains will be melted, the tensile strength and elongation will be reduced. With the increasing of stirring time, the grains firstly become fine, uniform and round, and then grow up. The tensile strength and elongation firstly increase, and then reduce.
