摘要:

应变玻璃相是通过在马氏体合金中掺杂少量杂质而产生的。它的基态被认为是由马氏体纳米畴空间上彼此分离的缺陷相。本研究,通过探测镍和钛周围的马氏体和应变玻璃组合物的Ni $_{50+x}$ Ti $_{50-x}$的局部结构,第一次,确定的缺陷相,负责抑制的弹性应变矢量的长程有序导致应变玻璃相的形成。

英文摘要:

The strain glassy phase is produced by doping a small percentage of impurity in a martensitic alloy. Its ground state is conceived to consist of martensitic nano domains spatially separated from each other by a defect phase. The present study, by probing the local structure around the Ni and Ti in martensitic and strain glassy compositions of Ni$_{50+x}$Ti$_{50-x}$, for the first time, identifies the defect phase that is responsible for inhibiting the long range ordering of the elastic strain vector leading to the formation of the strain glassy phase.
