The problem associated with die wear during extrusion processes cannot be overemphasized. In this work, the modified Archard's wear model is used as a subroutine which calculates the die wear depth of the extrusion process of magnesium ZK60 alloy in a C-shaped Equal Channel Reciprocating Extrusion (CECRE) die. The results show that the extrusion parameters, such as temperature, ram speed, and friction coefficient, have a ripple effect on the wear depth and strain-rate sensitivity values of the billet and dies. Also, the numerical results show that the wear depth and strain-rate sensitivity does increase with friction and extrusion temperature regardless of the ram speed. The applied punch load also increases as a function of the extrusion velocity and friction. Finally, this work provides a detailed and useful guide to selecting extrusion materials with durable die life at low production costs.

挤压过程中与模具磨损相关的问题怎么强调都不过分。在这项工作中，修改后的 Archard 磨损模型用作计算镁 ZK60 合金在 C 形等通道往复挤压 (CECRE) 模具中挤压过程的模具磨损深度的子程序。结果表明，挤压参数，如温度、冲压速度和摩擦系数，对坯料和模具的磨损深度和应变率敏感度值具有波纹效应。此外，数值结果表明磨损深度和应变率敏感性确实随着摩擦和挤压温度的增加而增加，而不管柱塞速度如何。施加的冲头载荷也随着挤出速度和摩擦力而增加。最后，
