Extrusion Process Optimization of Novel Automobile Radiator with Magnesium Alloy Containing Titanium

Novel automobile radiator containing titanium-magnesium alloy was produced with different extrusion temperatures,extrusion speeds and extrusion ratios,and the mechanical properties were tested and analyzed.The results show that with extrusion temperature from 320 ℃ to 420 ℃,extrusion speed from 1.5 m/min to 3.5 m/min and extrusion ratio from 12 to 24,the tensile strength of the radiator first increases and then decreases,and the elongation after fracture changes slightly. The optimized extrusion temperature,extrusion speed and extrusion ratio are 380 ℃,2.5 m/min and 20,respectively.
