摘要：

Low-alloyed transformation-induced plasticity steel (25 CrMo 4 and 15 CrNi 6) is produced by special heat treatments resulting in microstructures with variations in the content of retained austenite as well as the spatial arrangement of the austenitic grains. In this article, the influence of these variations on mechanical behavior is investigated. A continuum micromechanical unit-cell model is used to study the influence of external load on the strain-induced austenite-to-martensite phase transformation for selected microstructures. The model is implemented in an incremental formulation to a finite-element code.
