摘要

研究了中等Mn相变诱发塑性(TRIP)钢在25 ~ 300℃不同温度下的l ders变形行为。结果表明，l ders条带在所有的测试温度下都出现，但l ders应变不随温度单调变化。随着试验温度的升高，在l德氏带内同时观察到不同程度的马氏体相变。很好地验证了马氏体相变不是l ders带形成的原因，并对l ders应变随温度升高的非单调变化给出了合理的解释。

Temperature dependence of Lüders strain and its correlation with martensitic transformation in a medium Mn transformation-induced plasticity steel

The Lüders deformation behavior in a medium Mn transformation-induced plasticity (TRIP) steel is investigated at different temperatures ranging from 25 to 300 °C. It demonstrates that the Lüders band appears at all testing temperatures but with varied Lüders strains which do not change monotonically with temperature. The martensitic transformation is simultaneously observed within the Lüders band in varying degrees depending on the testing temperature. It is well verified that the martensitic transformation is not responsible for the formation of Lüders band, and a reasonable explanation is given for the non-monotonic variation of Lüders strain with increasing temperature.
