Abstract

The influence of the volume fraction of the martensite formed on cooling under stress on the martensite stabilization effect was studied in the Ni₅₀Ti₅₀ and Ni₅₁Ti₄₉ shape memory alloys. It was found that an increase in volume fraction of the martensite led to a rise in the martensite stabilization effect value for the A_f temperature regardless of the stress acting on cooling or chemical composition of the alloy. This was caused by an increase in volume fraction of the martensite increased the probability of the interaction between the martensite crystals that increased the damage of the interfaces.

应力冷却形成的马氏体体积分数对NiTi合金马氏体稳定效应的影响

研究了Ni50Ti50和Ni51Ti49形状记忆合金在应力冷却时形成的马氏体体积分数对马氏体稳定效果的影响。结果表明，无论冷却应力和合金的化学成分如何，马氏体体积分数的增加都会导致Af温度下马氏体稳定效应值的升高。这是由于马氏体体积分数的增加增加了马氏体晶体之间相互作用的可能性，从而增加了界面的破坏。
