通过模拟实际工矿条件,研究了不同相对冲击功条件下高锰钢加工硬化后的组织变化。结果表明在不同的相对冲击功阶段,高锰钢的加工硬化机制不相同,在低于50J/cm2冲击功时是位错滑移机制,在高于100J/cm2冲击功时是孪生硬化机制,而介于50J/cm2和100J/cm2之间时,是两者共同作用的结果。
Abstract：The microstructures of high manganese steel impacted with different relative impact energy(50、100 and 200 J/cm2) were investigated with optical microscopy and transmission electronic microscopy and the work hardening mechanism of the steel was also analyzed.The results show that the microstructures of high manganese steel hardened with different relative impact energy are different.The dominant work hardening mechanism is varys with relative impact energy.The dislocation hardening mechanism,twinning hardening mechanism and the compound hardening mechanism are observed in high manganese steel hardened with the relative impact energy less than 50J/cm2,greater than 100 J/cm2 and between 50J/cm2 and 100 J/cm2,respectively.
