The austenitic stainless steels are widely used in various industries due to its excellent properties. However, because of the martensitic phase transformation during the forming process, the austenitic stainless steels involve much more complex deformation behavior in comparison to the normal structure steels. Here in this paper, the deformation behavior of one austenitic stainless steel-Posco 1.4301, including the hardening behavior, yield behavior and formability behavior under different temperatures are comprehensively investigated by experimental, theoretical and finite element methods. Results show that martensitic phase transformation, which is related with temperature and strain, can greatly influence the plastic deformation behavior. This study provides a comprehensive understanding of the mechanical properties of this austenitic stainless steel and helps to better analyze the more complex deformation process in the future.

奥氏体不锈钢由于其优异的性能而被广泛用于各种行业。但是，由于在成形过程中发生了马氏体相变，因此与普通结构钢相比，奥氏体不锈钢的变形行为要复杂得多。本文通过实验，理论和有限元方法全面研究了一种奥氏体不锈钢Posco 1.4301的变形行为，包括在不同温度下的硬化行为，屈服行为和可成形性。结果表明，与温度和应变有关的马氏体相变可以极大地影响塑性变形行为。
