摘要
提出了金相法、硬度法、磁性法和残余奥氏体量法四种确定奥贝球铁最佳等温淬火时间的方法，并进行了实验验证。研究表明，这四种方法的综合使用，可以保证所测最佳等温淬火时间的准确性。
In this paper, four kinds of methods: metallography, hardness, magnetism and retained austenite were put up to measure the optimum austernpering time and their effctivness were verified by experiment. The results show that, by use of the four kinds of methods,the exact optimum austempering time can be obtained
