Influence of Tempering Transformation Induced Plasticity (T-TRIP) on the Evolution of Residual Stresses in Laser Heat Treated 50CrMo4 Steel

Abstract This study investigates the interaction between tempering processes and the formation of tempering transformation induced plasticity (T-TRIP) in 50CrMo4 steel during laser heat treatment. Various configurations, including single and double laser treatments, were examined along with different initial material states and heat treatment parameters.
