Abstract

The invention discloses high-formability magnesium alloy, comprising the following components according to percent by weight: 0.5-2.0% of Zn, 0.1-0.3% of Ce, 0.1-0.3% of Ca, </=0.015% of unavoidable impurity and the balance of Mg, and preferably, also comprising 0.01-0.3% by weight of Mn. With weak texture, the magnesium alloy provided herein may bear great stress and high stress rate without cracking during extrusion, rolling and other plastic deformations, and processing formability of the magnesium alloy is effectively improved.

Description

technical field [0001] The invention belongs to the field of metal material processing, and in particular relates to a magnesium alloy with high formability. Background technique [0002] Magnesium alloy has high specific strength, specific stiffness, good damping, machinability and thermal conductivity, strong electromagnetic shielding ability, easy recycling, regeneration and many other excellent properties, making it widely used in aerospace, automobile industry, electronics industry The application in the fields of national economy and national defense is expanding day by day. And magnesium is the lightest metal structure material, with a density of only 1.74g / cm3, which is 2 / 3 of aluminum and 1 / 4 of steel. The wide application of magnesium alloy in industry will have a positive effect on energy saving and emission reduction. Therefore, magnesium alloy is known as "the green engineering material of the 21st century". [0003] Traditional magnesium alloys such as Mg-Al ...
