摘要
为了解决模具钢生产中碳化物分布不均匀、颗粒大等问题,本文设计了脉冲电场退火和加热保温的热处理工艺改进方法。结果表明:采用改进的球化退火工艺能够有效细化材料的颗粒,使材料组织趋于均匀化,改进了宏观缺陷的分布;材料的综合力学性能也有明显的提高。
In order to sovle the problem of uneven distribution of carbides and granule, pulsed electric field annealing and heat treatment process of heat insulation method were designed. Results show that: material particles can be efficiently granulated using the improved spheroidizing annealing process; material microstructure is homogenization; the distribution of macro-defect improves; and integrated material has greatly improved mechanical properties.
