摘　　要：研究相变热模拟工艺对微合金钒氮钢显微组织和晶内铁素体形成的影响。对含氮量不同的两种V-N 钢进行了模拟,用光镜和电镜观察和比较了钢中的显徼组织转变特点。结果表明,随等温温度的降低及等温时间的延长,铁素体的转变量增加;增加钢中的氮含量,有利于铁素体生成,细化晶粒。Effect of transformation stimulation on micro structure formation during γ→α phase transformation were studied .The simulated were performed for two kinds of V-N steels. The characteristics of microstructure were observed using an optical microscope and a transmission election microscope.The results show that the transformation of ferrite is greatly enhancedrefined with the increase of nitrogen content.
