一、工具钢形变热处理可达到的性能和主要参数 与常规热处理相比,结构钢、弹簧钢和调质钢通过高温形变热处理所达到的性能变化特点是,在韧性和塑性不变或在两者均有改善的情况下,强度获得提高。在上述这些钢的高温形变热处理基础上,近年来对高合金钢也做了一些研究。由于高温形变热处理的采用,从而有可能使工具钢、热作模具钢、高速切削钢的使用性能(即强度、韧性、
First, the tool steel deformation heat treatment achievable performance and main parameters Compared with the conventional heat treatment, structural steel, spring steel and quenched and tempered steel by high temperature deformation heat treatment to achieve the performance change is characterized by the same toughness and ductility or in both In the case of improvement, the intensity is improved. Based on the high-temperature deformation heat treatment of these steels, some researches have been done on high alloy steels in recent years. Due to the high temperature deformation heat treatment used, it is possible to make tool steel, hot die steel, high-speed cutting steel service performance (ie, strength, toughness,
