Effect of pressure and preparing conditions on structure of bulk amorphous alloys

大块非晶合金又称大块金属玻璃,是一种具有特殊结构与性能的新型金属材料.本文利用同步辐射XRD技术研究了常压和11.6GPa压力下Zr41.2Ti13.8Cu12.5Ni10Be22.5大块非晶合金结构以及0～50GPa压力范围内Fe60Co10Zr8Mo5Nb2B15大块非晶形成合金结构特征的演变.另外,利用同步辐射XRD研究了冲击波处理和水淬条件下制备的Zr41.2Ti13.8Cu12.5Ni10Be22.5大块非晶合金微观原子构型的差异.研究表明,压力与制备条件对大块非晶合金的结构均有一定影响,本研究对深入了解大块非晶合金结构本质及进一步开发该类材料具有重要理论和现实意义.
