研究添加Y元素对CuZrAl块体金属玻璃的结构和力学性能的影响.结果表明,添加Y元素提高CuZrAl体系的玻璃形成能力,而且由于添加Y元素可以降低该体系的结合能,从而降低其断裂强度.Cu45Zr48Al7块体金属玻璃的断裂表面主要呈脉状,而Cu6Zr42Al7Y5块体金属玻璃的断裂表面则很平滑.TEM观察表明,Cu45Zr48Al7的微观结构为非晶基体中含有纳米相,然而Cu46Zr42Al7Y5块体金属玻璃为全非晶结构.

The effects of Y addition on the structural and mechanical properties of CuZrA1 bulk metallic glass (BMG) were studied.The results show that the glass forming ability of CuZrAl system is improved by the addition of Y and the fracture strength decreases with Y addition due to the reduction of binding energy induced by Y.The fracture surface is dominated by vein-like patterns in Cu45Zr48Al7 bulk metallic glass,and changes to smooth regions in Cu46Zr42Al7Y5 BMG TEM observation shows that Cu45Zr48A17 BMG has a composite microstructure of nanocrystalline phases dispersed in amorphous matrix.However,the Cu46Zr42Al7Y5 BMG shows a fully amorphous structure.
