摘要：
The microstructures and mechanical properties of Mg-Zn-Zr-Y alloy extruded bar with different heat treatment processes were investigated, including solution treatments of 400 degrees C, 450 degrees C and 500 degrees C for 3 hours followed by 170 degrees C x 24h aging treatment, and solely aging treatments of 160 degrees C, 180 degrees C for 24hours without solution after extruding. By comparing the grain size, strength and elongation of the samples, the heat treatment processes for extruded products with high strength and with medium strength were recommended.
