通过透射电镜研究了铈对铝硅合金共晶两相共格关系的影响。结果表明,适量的铈可使共晶两相共格关系{100}A_l//{110}Si明显化,改变了共晶硅的生长方式,有利于共晶硅的纤维条状生长。
The effect of cerium on the coherent relationship between eutectic and two phases of Al-Si alloy was studied by transmission electron microscope. The results show that the proper amount of cerium can make eutectic two-phase coherent relationship {100} A_l {{110} Si obvious, changing the growth mode of eutectic silicon, which is beneficial to the fiber strip growth of eutectic silicon.
