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.

采用具有可逆形状记忆效应的TiNi合金对静态岩石分离器进行了研究。所得结果如下：1. 适用于50.8at静态破岩机压力源的TiNi合金。%Ni合金在673K下，经1073K先固溶处理1h，在1073K下不经先固溶处理，分别约为600MPa和4.4%。建立了可逆形状记忆效应（RSME）的训练程序。循环变形训练对具有母相的合金是有效的。在Ti-50.5at时，随RSME的自发形状变化。在673K温度下，未经热循环固溶处理的%Ni的应变约为2%，约为相同材料中单向记忆最大恢复应变的45%。加热时的恢复应力约为420MPa，约为单向记忆最大恢复应力的70%。通过室内试验，证实了RSME合金在静态劈岩器中的适用性。本研究结果表明，TiNi形状记忆合金作为固体压力源具有广阔的应用前景。
