摘要
采用铸造、热挤压和热处理等传统手段制备了高性能Mg-Al-Zn系变形镁合金。研究表明:对于Al含量大于9%的镁合金,Zn元素对其挤压态力学性能的影响具体表现为:对于Al含量10%的合金,当Zn含量为2%时,其强度最高,而延伸率最低;而对Al含量为11%的合金,当Zn含量为3%时,其延伸率和强度均最好。
High-performance Mg-Al-Zn system wrought magnesium alloys were fabricated by the method of conventional foundry combined with hot extrusion and heat treatment. The results show that when A1 element content in the magnesium alloys is higher than 9%, the effect tendency of Zn element content on the properties of magnesium alloys is different. For 10%A1 magnesium alloys, when the content of Zn element is 2%, the tensile strength is highest, but the elongation least. However for 11% Al, when the content of Zn element is 3%, both the tensile strength and the elongation are optimum.
