中文摘要:
??????多组元的Zr基非晶合金成分的复杂性对开发具有优异玻璃形成能力的Zr基非晶合金提出巨大的挑战。另外,大部分Zr基非晶合金含有有毒元素Be或者贵金属。因此,采用一种简单有效的方法开发无毒无贵金属元素的多组元Zr基非晶合金十分必要。本文中采用二元共晶比例法和部分元素替代法快速的开发出了一种新的临界尺寸大于10mm的 Zr50Ti5Cu27Ni10Al8非晶合金。这个非晶合金的热稳定性和硬度也通过原位高温X射线衍射和纳米压痕方法测量得出。

英文摘要:
??????The wide compositional space of multi-component Zr-based metallic glass gives rise to a huge challenge for the discovery of the Zr-based alloys with excellent glass-forming ability. Moreover, most of the bulk-sized Zr-based metallic glasses contain either the toxic element Be or precious metals. Thus, economical approaches using to search multi-component bulk-sized Zr-based metallic glass free of poisonous and noble elements are extremely necessary. Here, a new Zr50Ti5Cu27Ni10Al8 metallic glass, with a critical diameter of 10 mm, was explored after only a few experimental trials through the method of proportional mixing of the binary eutectics and slightly partial replacing of element. The thermal stability and the hardness of this metallic glass were also respectively investigated by in-situ high-temperature X-ray diffraction and nanoindentation experiments.
