3Cr2Mo钢CCT曲线的测定与分析
Determination and analysis of CCT curves of 3Cr2Mo steel
摘要
Abstract
The different dilatometric curves of continuous cooling transformation were determined by Gleeble-1500 thermal mechanical simulation. By dilatometric change and DSC analysis referencing microscopic test and hardness measurement, the continuous cooling transformation (CCT) diagram was obtained. According to the CCT diagram obtained above, the transformation of austenite at different cooling rates were analyzed, and the relationship between the cooling rates and the variation of microstructure and hardness was disclosed. At last the similar transition curve was investigated. The results show that martensite transition critical cooling velocity is 1.0-1.5 ℃/s. All those provide the references for productive practice and establishing new technic.关键词
