    摘要:

    研究了电脉冲时效对预变形Fe-Mn-Si-Cr-Ni-C合金形状记忆效应及Cr23C6析出的影响。结果显示电脉冲处理能加速Cr和C原子的迁移及Cr23C6碳化物的析出,降低时效温度,缩短时效时间,能诱发Cr23C6碳化物的形核。在973 K时效时具有电脉冲处理的预变形Fe-Mn-Si-Cr-Ni-C合金与没有电脉冲处理的合金相比,其形状回复率在30 min内从淬火合金的32%提高到最大值89.2%。

    Abstract:

    Effects of ageing with electric pulse treatment on shape memory effect and precipitation of Cr23C6 carbide in a pre-deformed Fe-Mn-Si-Cr-Ni-C alloy were investigated. The results showed that electric pulse treatment could accelerate the migration of Cr and C atoms and precipitation of Cr23C6 carbides, lower ageing temperature, shorten ageing time and induce the nucleation of Cr23C6 carbides. Therefore, the shape recovery ratio was improved to the maximum value 89.2% from 32% of a water-quenching alloy within 30 min in a pre-deformed Fe-Mn-Si-Cr-Ni-C alloy aged with electric pulse treatment compared to alloys aged without electric pulse treatment at 973 K.
