FORMATION OF AMORPHOUS Cu60Zr40 AND Ni50Zr50 POWDERS BY MECHANICAL ALLOYING
-
Abstract
Amorphization of Cu-Zr and Ni-Zr systems by mechanical alloying(MA) was studied by X-ray diffraction. The results show that the amorphization is not merely a simple interdiffusion by thermal activation; in addition, the strain induced by MA also accelerates this process. -
