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.

通过不同冷却速度下的热模拟试验,研究了铌微合金化对轴承钢碳化物网状的影响.结果表明,不同冷速条件下,含铌钢和不合铌钢中的碳化物网状级别差别不大;当冷却速度大于5℃/s时,碳化物网状级别小于1级;含铌轴承钢的珠光体团尺寸小,碳化物网状不连续分布.铌微合金化对碳化物网状的影响主要通过细化珠光体团和改变碳化物网状的形态来体现.
