Abstract We discovered Elinvar effect in a severely cold worked Ti-50.8(at%)Ni thin belt that showed a modulus variation of less than 0.54GPa(∼1%) over a wide temperature range (−50 to 100 °C). Microstructural analysis showed an unraveled amorphous matrix dotted with nanosized crystallites, which demonstrated that the softening of the nanodomains in the retained nanosized crystallites and hardening of the amorphous matrix during cooling over wide temperature range can trigger the Elinvar effect.

严重变形的 Ti-50.8(at%)Ni 薄带中的 Elinvar 效应

摘要 我们在严酷冷加工的 Ti-50.8(at%)Ni 薄带中发现了 Elinvar 效应，该薄带在很宽的温度范围内（-50 到 100 °C）显示出小于 0.54GPa（~1%）的模量变化。微观结构分析显示散布着纳米级微晶的散开的非晶态基体，这表明保留的纳米级微晶中纳米域的软化和非晶态基体在很宽的温度范围内冷却过程中的硬化可以触发艾林瓦效应。
