摘　　要：在冲击磨损条件下 ,关于高铬铸铁中的残留奥氏体的作用 ,在国内及国外都有不同的看法。为此进行了MLD 10的冲击磨损试验、单点冲击试验和落球试验。试验结果表明 ,残留奥氏体均不利于各种条件下的磨损 ,探讨了消除残留奥氏体的措施。There are different ideas about the effect of retained austenite in high chromium irons under impact wear conditions. Impact wear tests on tester MLD 10, single point impact test and ball on ball test have been carried out. The experimental results showed disadvantageous effect of retained austenite. These data may be useful to join the discussion of the effect of retained austenite and to clarify this phenomenon.
