摘　　要：以T/P91钢为研究对象,在连续介质损伤力学模型(CDM)基础上研究了T/P91钢蠕变机制。通过计算机仿真和文献实验结果分析可知,模拟T/P91钢材的蠕变曲线必须考虑空洞形核长大、溶质原子贫化以及Laves相粗化等损伤影响,才能获得比较真实的蠕变曲线。Taking T/P91 steel as research object, the creep mechanism of T/P91 steel was studied based on the continuum damage mechanics model. The computer simulation and experimental results show that the impact of cavities nucleation and growth, solute atom dilution and Laves phase coarsening and other damage must be considered in the simulation of creep curves of T/P91 steel to obtain the real creep curves.
