Abstract

Structures of Zr70Ni20Al10, Zr70Cu20Al10, Zr70Cu30 and Zr70Ni30 amorphous alloys were analyzed by high-energy X-ray diffraction. The relatively stable Zr2Cu amorphous alloy shows a local atom arrangement different from the Zr2Cu crystalline phase. By contrast, the less stable Zr70Ni30 amorphous alloy has a structure similar to Zr2Ni. In the Zr70Cu20Al10 metallic glass, Zr-Al nearest neighbor pairs are introduced in the amorphous structure. In the Zr70Ni20Al10 metallic glass, the strong correlation between Zr-Ni pairs is drastically modified by the formation of Zr-Al pairs. The presence of Zr-Al pairs in the ternary alloys suppresses the crystallization and stabilizes the glassy state.
