The temperature variation, phase transformation and phase-transformation plasticity are the main factors of inducing the initial strain in the quenching. In order to understand their effect on the residual stress of quenched part, a plane strain component is regarded as the study objective, and its FEM model is built. The effects of the initial strains on the quenching residual stresses are simulated...
The optimal design of the quenching quality using technical parameters is a problem with high dimensional multi-objective and with complicated calculations & constraints. A novel general method for high dimensional multi-objective optimal design is presented based on degree of grey incidence with hybrid discrete variables. Making response surface mathematical model, multi-objective optimization...
