Abstract Martensitic transformation induced by strain in duplex stainless steels is a good option to increase their strength and elongation. The influence of low deformation levels on the phase transformation was studied in a 2304 lean duplex stainless steel. It was demonstrated that this steel exhibited the phase transformation of austenite (γ) into epsilon (e) and alpha (α′) martensite after cold rolling. The e and α′ were observed in shear bands and close to the grain boundaries. The Shoji–Nishiyama relation 110 γ / / 2110 e was observed. Hitherto, the e formation has not been reported in the literature for this steel by cold deformation.

贫双相不锈钢中低应变的ε-马氏体形成

摘要 双相不锈钢由应变引起的马氏体相变是提高其强度和延伸率的良好选择。在 2304 贫双相不锈钢中研究了低变形水平对相变的影响。结果表明，该钢在冷轧后表现出奥氏体（γ）向ε（e）和α（α'）马氏体的相变。在剪切带中观察到 e 和 α' 并靠近晶界。观察到了 Shoji-Nishiyama 关系 110 γ / / 2110 e。迄今为止，文献中还没有关于这种钢通过冷变形形成 e 的报道。
