ZG80CrMnMo钢的CCT曲线及组织研究
Study on CCT Curve and Microstructure of ZG80CrMnMo Steel
摘要
Abstract
The CCT (Continuous Cooling Transformation) curve of ZG80CrMnMo steel was measured on Gleeble-1500 thermal trial simulator, the microstructure and hardness of transformation products under different cooling velocities were observed. The structure transformation regularity with being cooled continuously were emphatically researched at the cooling rate form 1℃/s to 45 ℃/s. The results show that CCT curve shift to the right, pearlite and bainite transformation are inhibited, martensite and residual austenite can easier-to-obtain within the studied of scope cooling rate. The CCT curve of ZG80CrMnMo steel can provide a instruction for producing martensitic steels.关键词
