本标准规定了镍钛形状记忆合金相变温度测定方法 - 弯曲和自由回复法。
本标准适用于通过测量热相变过程的回复变形量测定马氏体逆相变相变温度,适用于马氏体逆相变终了温度Af 介于-25℃~90℃的完全退火态或热处理态丝材、管材或者带材。
Scope
This standard specifies the method for determining the phase transformation temperature of nickel-titanium shape memory alloys - the bending and free recovery method. This standard is applicable to the determination of the martensite reverse phase transformation temperature by measuring the recovery deformation during the thermal phase transformation process. It is applicable to the fully annealed state or heat treatment where the end temperature of the martensite reverse phase transformation A is between -25 ℃ ~ 90 ℃. wire, tube or strip.
