A study on the static rock splitter using TiNi alloy with reversible shape memory effect has been performed. Results obtained are as follows. 1. Suitable TiNi alloy for the pressure source of the static rock breaker 50.8at.%Ni alloy at 673K for 1h with prior solution treatment at 1073K for without prior solution treatment were about 600MPa and 4.4%.2. Training procedure of generating reversible shape memory effect (RSME) has been established. Training of cyclic deformations was effective for the alloy with parent phase. The spontaneous shape change with RSME in Ti-50.5at.%Ni aged at 673K without prior solution treatment during thermal cycle was about 2% in strain, which was about 45% of the maximum recovery strain of one-way memory in the same materials. The recovery stress on heating was about 420MPa, which was about 70% of the maximum recovery stress of one-way memory.3. The applicability of RSME alloy to the static rock splitter has been confirmed by laboratory experiment. The obtained results in the present study indicates that TiNi shape memory alloy has a bright prospect as a solid pressure source.

已经对具有可逆形状记忆效果的Tini合金对静态岩石分离器进行了研究。获得的结果如下。 1。用于静态岩石破碎机的压力来源的合适的Tini合金50.8at。％Ni合金为673K，为1H，在未经事先溶液治疗的情况下进行1073K的先前溶液处理，约为600MPa和4.4％.2。已经建立了生成可逆形状记忆效应（RSME）的训练程序。循环变形的训练对于与母相的合金有效。在TI-50.5AT中使用RSME的自发形状变化。在673K时以673K年龄在673K中，在热周期中没有事先溶液治疗的菌株中约为2％，约为同一材料中单向内存最大回收应变的45％ 。加热的恢复应力约为420MPa，约为单向内存最大回收应力的70％。3。 RSME合金对静态岩石分离器的适用性已通过实验室实验确认。在本研究中获得的结果表明，Tini形状的记忆合金作为固压源具有明亮的前景。
