Bainite transformation under the effect of large stress in a carbide-free bainite steel
Journal of Materials Research and Technology, 2023 The effects of large stress on bainite transformation and microstructure were investigated by dilatometry, SEM and EBSD. The results show that the effect of large stress on bainite transformation includes two parts: mechanical driving force and prior ...
