Abstract Strain-induced phase transformation in a dual-phase Mg–Li alloy after a severe deformation has been investigated. β-Li phase was transformed into α-Mg phase as a consequence of large strain cold rolling. The morphology and density of the strain-induced phase could be controlled by slip activation in the β-Li phase. A multi-direction rolling procedure was designed to enhance phase transformation behavior. High density strain-induced phase refined phase structure and greatly promoted the yield strength of the material without a sacrificing the ductility. Strain-induced phase transformation is a potential method for improving the mechanical properties in dual-phase alloys.

在室温下通过应变诱导相变强化双相 Mg-Li 合金

摘要 研究了严重变形后双相 Mg-Li 合金的应变诱导相变。由于大应变冷轧，β-Li 相转变为α-Mg 相。应变诱导相的形态和密度可以通过 β-Li 相中的滑移激活来控制。设计了多向轧制程序以增强相变行为。高密度应变诱导相细化相结构，在不牺牲延展性的情况下极大地提高了材料的屈服强度。应变诱导相变是改善双相合金力学性能的一种潜在方法。
