摘　　要：对45钢和20CrMoH钢奥氏体晶粒度显示进行优化,选择常用的苦味酸腐蚀法检测奥氏体晶粒度,通过控制试验的腐蚀温度和腐蚀时间,优化了45钢和20CrMoH钢奥氏体晶粒显示的检测方法,使得奥氏体晶粒显示更加清晰。The austenite grain size display of 45 steel and 20CrMoH steel was optimized.The commonly used picrate corrosion method was selected for the detection of austenite grain size.The corrosion temperature and corrosion time were controlled to optimize the detection method of austenite grain size display for 45 steel and 20CrMoH steel,so that the austenite grain size display was clearer.

关 键 词：45钢 20CRMOH钢 奥氏体晶粒度 腐蚀温度 腐蚀时间
