Abstract：Using the means of JmatPro material performance simulation software combined with experimental research，the microstructures of three kinds of ZG1Cr10NiAlMoVNbN heat-resistant steels with different[w(Al)]after normalizing and high-temperature tempering were studied. Three kinds of test steels were simulated at room temperature and the fracture mechanism was analyzed according to the tensile test data and fracture morphology. The results show that the simulation results are in good agreement with the experimental results. With the increase of[w(Al)]in the steel，the fracture mechanism changes from microporous aggregated fracture to quasi-cleavage fracture and cleavage fracture. Combined with microstructure analysis，the[w(Al)]is the main factor on the carbide type，shape and distribution.
