摘要
用Ｘ－射线仪、扫描电镜和透射电镜系统研究了铝对钨钼系高速钢持态、退火以及淬回火组织的影响。铝含量超过２．０％时，淬火组织中出现含析出合金相的铁素体组织和晶界屈氏体，导致钢硬度的降低。
The aluminum on as-cast, annealed and quenched microstructure and hardness of high speed steelW9Mo3Cr4V was studied systematically using scanning,transmission electron microscopy. The results showthat, with aluminum more than 2.0% in steel, the ferrite containing alloy phase deposit and the troostite atgrain boundary have been found in structure of quenched steel resulting in decreasing of hardness.
