摘要 对钒在珠光体组织转变中的作用进行了研究 ,结果表明 :钒在 PD3钢中可起到细化珠光体 ,使渗碳体片变得不规则的作用 ,但钒对珠光体团大小影响较小。当 PD3钢中钒含量增加到 0 .3 3 %时 ,碳氮化钒将大量析出 ,并使珠光体片间距反常粗化 。 The affect of Vanadium in pearlite transformation has been studied.Present results show that Vanadium atoms in PD3 steel could refine pearlite,and make cementite irregular,but affect a little on size of pearlite.For PD3 steel containing V more than 0.33 %,Vanadium carbide precipitates a lot,and makes the pearlite lamellar gap coarsen abnormally,deteriorating the toughness.
