The structure of the intermetallic phases MoAl₁₂, ReAl₁₂and TcAl₁₂

Abstract

X-ray methods were used to refine the structures of MoAl/sub 12/, ReAl/ sub 12/, and TcAl/sub 12/. The unit cell is bcc and the structures are nearly the same as that of WAl/sub 12/. The interatomic distances of the three phases are compared and those of MoAl/sub 12/ are compared with distances in other Mo- Al phases. (auth)
