对加硼改良高速钢M2+2.0 B快速凝固条带进行了时效处理及淬火回火处理,分析了不同温度处理后硬度变化;用透射电镜、X射线衍射仪对其组织进行了分析;为进一步研制该类高速钢进行了初步的探索。
The rapid solidification ribbons of M2 + 2.0 B modified high-speed steel with boron addition were treated by aging treatment and quenching and tempering. The hardness changes after different temperature treatments were analyzed. The microstructure was analyzed by transmission electron microscopy and X-ray diffraction. Development of such high-speed steel conducted a preliminary exploration.
