Effect of Overaging in Continuous Annealing Process on Microstructures and Properties of C-Mn Steel

在热模拟实验机上模拟了连续退火过时效工艺,研究了过时效温度和过时效时间对0.08C-0.15Si-1.50Mn钢组织和性能的影响.结果表明:过时效温度为350～550℃,保温时间1～20 min时,实验钢组织均由铁素体及分布在铁素体晶粒间的贝氏体组成;实验钢抗拉强度与贝氏体中M-A岛含量和M-A岛中的碳含量有关;随过时效温度升高,M-A岛含量出现"峰值",随过时效时间延长,M-A岛中的碳含量也出现"峰值".
