摘　　要：介绍了一种侵蚀奥氏体晶界的方法。在40℃恒温水浴下,用过饱和的苦味酸水溶液100mL+雕牌高效洗洁精2mL,可以清晰地显示2.25Cr1Mo0.25V钢的奥氏体晶界。A method was investigated to reveal austenite grain boundary: with the aid of a water-heater controlled at the temperature of 40℃, using 100mL supersaturated picric and 2mL diao brand high-efficiency abluent, the austenite grain boundary can be clearly revealed.

关 键 词：2.25CR-1MO-0.25V钢 奥氏体晶界 侵蚀
