The effect of plastic deformation of V nanowires on the transformation characteristics of two NiTiV alloys was investigated. A significant increase of B19′→B2 transformation temperatures in the deformed samples during the initial heating process was found. In the subsequent cooling process, the R→B19′ transformation temperatures were higher than the as-annealed samples. Upon second heating, the B19′→R transformation temperatures were higher than the as-annealed samples, but the change was much smaller than the R→B19′ transformation. All of these phenomena are closely related to the plastic deformation of V nanowires during deformation.

V纳米线的塑性变形对NiTiV合金相变特性的影响

研究了V纳米线的塑性变形对两种NiTiV合金相变特性的影响。发现在初始加热过程中，变形样品中的B19'→B2相变温度显着增加。在随后的冷却过程中，R→B19'相变温度高于退火后的样品。在第二次加热时，B19'→R相变温度高于退火后的样品，但变化远小于R→B19'相变。所有这些现象都与V纳米线在变形过程中的塑性变形密切相关。
