The explosive hardening of high Mn Steel was simulated by using light gas gun under selected ranges of impact load from 10 to 20 GPa and pulse duration from 0.04 to 1.6μs.The experi- mental results showed that a lot of twins formed in the shocked high Mn steel may be the prin- cipal cause of explosive hardening.

选择压力峰值10—20GPa、脉冲宽度0.04—1.6μs等一系列脉冲载荷,利用轻气炮等模拟爆炸硬化过程,探索高锰钢爆炸硬化的微观机制,根据实验结果判断,激波作用后高锰钢中产生的大量孪晶是引起高锰钢爆炸硬化的主要原因。
