Abstract

In this research, the equal channel angular pressing (ECAP) process of AM60 magnesium alloy was investigated by the finite element simulation as well as experimental test. The effect of process parameters on required force and strain distribution was also assessed. The simulation results were verified by the experimental tests. Using the full factorial design of experiments, effects of friction and process temperature were explored. The results indicated that an increase in the friction coefficient will significantly enhance the amount of pressing force (4-fold). Also, the effect of friction on process force was higher at lower temperatures and decreased with the rise of temperature. An increment in the friction coefficient from 0.02 to 0.08 raised the maximum strain by 9%. Furthermore, the maximum strain showed enhancement with temperature elevation.
