摘要
通过抗弯强度试验分析了M42高速钢刀具的热处理硬度与韧性之间的关系 ,提出采用等温淬火工艺将M42高速钢刀具的硬度控制在 6 5～ 6 7.5HRC可获得较佳切削性能。
The relationship between the heat treating hardness and ductility of M42 HSS cutting tool is analyzed through the bend strength test. It is pointed out that the heat treating hardness of M42 HSS cutting tool shall be held in 65～67.5 HRC by the isothermal hardening to acquire the good cutting performance.
