Article Preview

The distribution of Rare Earth element on the cast of A356 and the effect of the first α phase by the Rare Earth element asymmetric distribution has been discussed in the paper. It is showed by the research, that the condition of interphase is changed by Rare Earth element asymmetry distribution, which influences the process ofαphase growing and facilitates the growth of α phase in sphere, and leads to a optimal Rare Earth quantity for facilitative effect, which is 0.5% in this experimentation, and that αphase grain will be change to small by adding Rare Earth.
