本文讨论了铁素体-马氏体双相钢的宏观初始流变行为的特点及其原因。为此，连续微观力学有限元模拟模型微观结构的结果。在双相钢的生产过程中，其微观结构的一部分，即奥氏体转变为马氏体，从而扩大。这在它们的微观结构中引起“相变诱发”残余应力和塑性应变。确定这些量来控制这些钢的初始流动行为。
In the present work, peculiarities of the macroscopic, initial flow behavior of ferritic-martensitic dual-phase steels and their causes are discussed. For this purpose, results of continuum-micromechanical finite-element simulations on model microstructures are presented.During production of dual-phase steels, a portion of their microstructure, i.e. austenite transforms to martensite and thereby expands. This causes “transformation induced” residual stresses and plastic strains in their microstructure. These quantities are identified to govern the initial flow behavior of these steels.
