摘　　要：本文对双相钢的双屈服特性进行了分析。试验结果指出,双相钢的双屈服特性的产生是由于马氏体相从弹性变形过渡到塑性变形以及相界面微空洞萌生的结果。两相的相对量和组织形态,影响着双屈服特性。根据两相不同的变形特征,把双相钢的均匀变形过程分为三个阶段。In this paper, the duplex yield character (DYC) of dualphase steel has been discussed. The results of the tests show that the DYC is due to the martensite deformation from the elastic state to the plastic state and the microvoid formed from the interphase boundaries. The DYC is directly affected by the phase ratio and the shape of structure. According to the different deformation character of the duplex phase, the uniform deformation of dual phase steel divide into three stages.
