FORMATION OF AMORPHOUS Cu₆₀Zr₄₀ AND Ni₅₀Zr₅₀ POWDERS BY MECHANICAL ALLOYING

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.
