摘要：

Mg-3Al-1Zn round ingots were divided into several pieces and then cobbled together to introduce specific interfaces before direct extrusion. The microstructure, texture and mechanical response of the magnesium alloys processed by conventional extrusion and co-extrusion with introducing various interfaces were examined. The results indicated that the prewired various interfaces played important role on the microstructure evolution and texture modification of magnesium alloys during extrusion, and consequently influenced the tension-compression performance of the extruded alloys. Co-extrusion process by introducing appropriate interfaces during extrusion was suggested as a sample and effective method to enhance the comprehensive mechanical properties of Mg-Al-Zn alloys.
