摘　　要：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。In this paper, the rapidly solidified boron modified M2 + 2. 0 B ribbon was aged, quenched and tempered. The variation of hardness of specimens treated at varriant temperatures was analyzed. TEM and X-ray diffraction techniques were employed to analyze the microstructure. Further process for manufacturing rapidly solidified boron modified high-speed steel was explored preliminarily.
