摘要
针对1Cr12Mo耐热钢调质热处理后晶粒粗大的问题进行晶粒细化热处理工艺的研究。提出了多种晶粒细化热处理工艺方法,并对其处理结果进行比较。指出该材料最佳的晶粒细化热处理工艺是:两次亚温淬火+高温回火工艺。
Regarding to the grain grossness of 1Cr12Mo heat resisting steel after quenching and tempering process, the research on grain refinement heat treatment process has been operated. Then many grain refinement heat treatment processes have been represented with the comparison of results. Furthermore, the best grain refinement heat treatment process for this material is twice sub-temperature quenching ＋ high-temperature tempering process.
