to analyze an asymmetric stepped shaft. To evaluate the MCWR process and better understand its deformation characteristics, the material flowing mechanisms, temperature distributions, strain and rolling..., temperature distributions, strain, and rolling force were analyzed based on Deform-3D. The correctness of the finite element simulation is verified by experiment. 2 Numerical model for multi-wedge......
id="ChDivSummary" name="ChDivSummary"><正>A new algorithm for pass adaptation in plate rolling is developed to improve thickness accuracy of plate products. The feature of the algorithm is that it uses the measured data rather than the schedule calculated data in adaptation, which leads to notable improvement in prediction accuracy of the rolling parameters and thickness accuracy of products......
temperature is 850 ℃, and the strain rate is 1 s-1. The rolling processes with more passes and weak deformation (Project 1) and with few passes and strong deformation (Project 2) were used, respectively..., unlike dislocation counteracts on the same slip plane by dislocation climbing at high temperature, which results in the decrease of dislocation density. When work hardening rate and softening rate were......
