The Influence of Extrusion Process Parameters and Heat Treatment on the Mechanical Properties of High-Strenght Magnesium Alloy
The article consists test results of direct extrusion AZ80A & ZK60A magnesium alloys. Extrusion process was conducted in the temperature range 350°C-450°C at different extrusion speeds (ram speed 0.8 mm/s and 2.8 mm/s). In order to find optimum precipitation strengthening parameters the aging curves have been made. Extruded rods were characterized by mechanical properties in different tempers. Basic structure researches of magnesium alloys have been made.
