Analysis on the FEM of AZ31 magnesium alloy channel extrusion based on the orthogonal test

In order to explore the extrusion process effect law on the AZ31 magnesium alloy channel, it has been analyzed that the influence significance order and laws of extrusion temperature, ram speed, extrusion ratio, die angle and die bearing length on the extrusion pressure, stress and the outlet temperature, based on orthogonal design of optimization methods in combination with DEFORM finite element numerical simulation. The optimized process parameters were obtained. The results show that the extrusion temperature is the most significant influence on the extrusion pressure, stress and the outlet temperature, and the extrusion speed play the second impact of the three objectives, and the die bearing length is not significantly affected.
