Study on hydrogen embrittlement sensitivity of vanadium microalloyed martensite-bainite steel

  • 摘要: 借助扫描电镜、透射电镜等手段对比研究了无钒和含钒(0.15%)马氏体-贝氏体钢的氢脆敏感性。试验结果表明:钒元素的添加会细化马氏体-贝氏体钢中的原奥氏体组织,并且会增加钢中马氏体相的占比,经回火后钢中钒元素会以碳化物的形式析出,使钢的氢脆敏感性降低。这主要是由于试验钢经钒微合金化后,增加了原奥氏体晶界及碳化物/基体界面等作为氢陷阱的数量,氢捕获位点增加,使氢原子在钢中的扩散系数明显降低,氢原子分布更加分散。
