In order to optimize the extrusion process parameters of Mg-8Al-0.5Zn-0.5Ti magnesium alloy plates containing titanium and magnesium alloy, and to provide experimental data and reference for the in-dustrial production,the extrusion experiments had been carried out on the extrusion line with various ex-trusion temperature,extrusion speed and extrusion ratio.And the resulting microstructure observation and mechanical properties test had been performed.The results showed that when the extrusion temperature in-creased from 300℃ to 360℃, and the extrusion speed increased from 1 m/min to 5 m/min,or the extru-sion ratio increased from 8 to 16,grain size of the plate was firstly refined and then coarsened, and the me-chanical properties of the plate were firstly improved and then decreased.Comparing with the extrusion temperature at 300℃,the tensile strength and yield strength of the plate extruded at 350℃ increased by 22.7% and 34.0%,respectively.The optimized extrusion temperature,extrusion speed and extrusion ratio were 350℃,3 m/min and 14,respectively.
