| 摘 要： | 选用45，40Cr,40CrNiMo和38CrMoAlA钢等碳钢和合金钢，进行了氧化法检验钢的奥氏体晶粒的试验。试验结果表明，钢表层的氧化和脱碳将使氧化法检验钢的奥氏体晶粒度变得很复杂，尤其是抗高温氧化能力强和脱碳倾向大的合金钢，氧化和脱碳将对奥氏体晶粒度的显示的评级带来极大的困难。

| Abstract: | The paper elaborates an experiment,whose purpose is to test austenite grain size using oxidizing method on selected carbon steel and alloy steel like 45,40Cr,40CrNiMo and 38CrMoAl,the findings of which show that the oxidation and decarburization of the steel surface layer complicate the test itself,and the oxidation and decarburization~ leave it rather difficult to display and grade the austenite grain size especially of the alloy steel with capacity of oxidation great to decarburization and strong oxidation resistance under high temperature. |
