【摘要】 用TEM原位观察方法,对近等原子比的TiNi合金在降温过程中的结构变化进行了研究。伴随着母相转变为R相和马氏体相时,对应的晶体结构变化为有序体心立方转变成菱面体和单斜结构。更多还原

【Abstract】 The structure transformation of near-equiatomic TiNi alloy is studied by means of in-situ observation during cooling in TEM. The crystal structure transforms from ordered bcdy-centered cubic to rhombohedral and monoclinic when high-temperature parent phase changes into low-temperature R-phase and martensitic phase.更多还原
