Stress or strain induced martensitic and bainitic transformations during ausforming processes

, 2020
The so-called ausforming treatment consists in plastically deforming a fully austenitized steel below the recrystallization stop temperature, prior to either a martensitic or a bainitic transformation.

Enhanced mechanical properties of 100Cr6 bearing steel through formation of nanobainite structure during ausforming treatment

Journal of Alloys and Metallurgical Systems
In this study, during an ausforming treatment, the specimens were austenitized at 1100°C and then exposed to rolling process at temperature of 300 °C by different degrees of deformation; 5, 10 and 15 %, and finally were undergone an austempering ...

Effect of ausforming temperature and strain on the bainitic transformation

, 2023
In this work, the effect of ausforming temperatures and strain level on bainitic transformation and morphology were investigated on a newly developed carbide-free high-silicon steel. High plastic deformations (0.2 ÷ 0.5%) were applied to undercooled austenite after austenitization in the temperature range 900-330 °C with a Gleeble 3800 thermomechanical
