The grain size is increa seda little and Rockwell hardness is decreased a little by solid solution treatment at the temperature below grain coarsening temperature(1150 ℃) due to undissolved carbo-(nitride),but grain grow rapidly and Rockwell hardness de.结果表明,弥散分布的碳氮化物对晶粒长大有显著阻碍作用,在低于该钢的晶粒粗化温度(1 150℃)固溶处理时,大量未溶解的碳氮化物使得晶粒尺寸增幅较小、洛氏硬度小幅下降;在高于1 150℃时,随温度的升高或时间延长,晶粒长大迅速,洛氏硬度大幅下降;晶粒生长指数随固溶温度的升高而呈台阶式增长;在固溶温度为1 050~1 100℃下的晶粒长大激活能为189。
