摘要：
A Zr-rich phase,NiZr,with low melting point has been fouhd in an NiAl alloy doped withZr(1.2at.-%).It will cause the incipient melt of the alloy after being homogenized at 1300℃.This makes it difficult to homogenize the coarse casting structures completely and limits thefurther improvement of properties of the NiAl alloy.
