Modeling of Reversed Austenite Formation and Its Effect on Performance of Stainless Steel Components

Abstract The kinetics of reversed austenite formation in 301 stainless steel and its effect on the deformation an automobile front bumper beam are studied by using modeling approaches at different length scales. diffusion-controlled is Johnson–Mehl–Avrami–Kolmogorov (JMAK) model, based experimental data. model can be used to predict volume fraction a temperature range 650–750 °C. A three-dimensional elastoplastic phase-field study diffusionless shear-type 760 simulations show that reversion initiates martensite lath boundaries proceeds inwards laths due high driving force such temperature. (RA) subjected side impacts finite element (FE) analysis. FE presence increased critical speed which yielded failed. RA also affects performance beam.
