直接淬火硬化钢晶粒度腐蚀剂的选用

Selection of a Corrosive for Direct Quenching Method to Determine Grain Size

就38CrMoAl、20CrMnTi两种钢的几种试验分析并总结出比较快速准确显示直接淬火硬化钢晶粒的腐蚀剂。

This article presents some grain size determining experiments for the steels 38CrMoAl and 20CrMnTi. An experimental eorrosive whieh eould demonstrate the morphology of grain size in the tested steel more quickly, aeeurately is suggested.
