摘　　要：以生产中多次正火仍无法消除粗大组织的车辆钢为试验材料,研究了加热转变中奥氏体形核、长大的基本规律及其影响因素。制定了细化车辆钢粗晶组织的热处理工艺并应用于生产,挽救了一批因晶粒粗大而行将报废的车轴,取得了良好的效果。The influence of heat treatment factors on the nuclei formation and growth of austenite in 40 axletree steel which normalized conventionally for multipass but still had coarse structure has been studied. Based on above results,an advanced heat-treating process for grain refining has been put forward. Applying this process in production a batch of axletrees with coarse grain structure have been retrieved from waste.
