作者研究了不同热-机械处理的 Ti-Ni 合金的热循环对转变温度的影响。将不同镍含量的样品进行溶液处理时,发现转变温度随热循环而变化,然而,富镍样品经冷加工后,在低于再结晶温度时时效及退火过程中发现,即使在热循环之后,它们的转变温度也是恒定的。透射电子显微镜检查揭示了在样品的溶液处理中,随热循环而产生位错,其密 The authors investigated the effect of thermal cycling on the transformation temperatures of different thermo-mechanically treated Ti-Ni alloys. When samples with different nickel contents were treated by solution, the transition temperature was found to change with the heat cycle. However, after cold working of nickel-rich samples, aging below the recrystallization temperature and during annealing, it was found that even after thermal cycling, The transition temperature is also constant. Transmission electron microscopy revealed dislocations with heat cycling in the solution treatment of the sample, with dense
