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。
补充资料：罗氏硬度
分子式：
CAS号：
性质：又称罗氏硬度。表示材料硬度。一种标准。用符号HR表示。应用压入法把压力施加在金刚钻尖上，使压入所试材料的表面而产生凹痕。用测得的凹痕深度来表示硬度。标度数越大，硬度越小。用于测定塑料、绝缘材料和金属材料等的硬度。
