系统研究了氮对Ti 42. 5Cu 40 Zr 10 Ni 5Sn 2. 5非晶合金形成和力学性能的影响。有人发现，少量的氮添加促进玻璃形成抑制竞争共晶结构的形成。与通常使比强度劣化的大原子尺寸元素（诸如Hf和Pd）不同，氮还可以增加当前Ti基BMG的比强度。研究结果不仅有助于从总体上理解非晶形成能力，而且有助于开发具有更高非晶形成能力的高性价比、高性能钛基大块金属玻璃。
Effects of nitrogen addition on glass formation and mechanical properties of the Ti42.5Cu40Zr10Ni5Sn2.5metallic glass were systematically investigated. It was found that a small amount of nitrogen addition facilitated the glass formation by suppressing formation of the competing eutectic structure. Unlike large atomic size elements such as Hf and Pd which usually deteriorate specific strength, nitrogen can also increase the specific strength of the current Ti-based BMGs. The results are not only helpful for understanding glass-forming ability in general, but also useful in developing cost-effective, high-performance Ti-based bulk metallic glasses with enhanced glass-forming ability.
