摘要
采用物理模拟的方法研究了W6Mo5Cr4V2钢裂纹愈合区的组织特点。通过扫描电镜观察发现,在真空加热条件下高速钢裂纹的愈合过程与碳化物的生长有密切关系。碳化物在裂纹区的生长和聚集所产生的"桥接"作用实现了裂纹面之间的冶金结合。分析了碳化物在裂纹区的生长过程。
The microstructure characteristics of the crack healing area in W6Mo5Cr4V2 steel were investegated by means of physical simulation. It was found through SEM observation that there is a close relation between the crack healing process and the carbide growth for the high-speed steel under the vacuum heating condition. It is ＂bridge＂ action produced by the growth and the accumulation of carbide in the crack area to realize the metallurgical binding between cracking faces. The growth process of the carbide in the crack area was analyzed.
