Problems solved by technology

Magnesium and magnesium alloys have a series of advantages such as low density, high specific strength and specific stiffness, and good impact resistance. However, when used as structural materials, their application is greatly limited due to the unsatisfactory hardness, strength, and wear resistance.

Abstract

The invention discloses magnesium alloy which comprises the following components in percentage by mass: 0.5-1.5% of carbon fiber composite, 0.5-1.5% of zinc, 1-2% of manganese, 0.05-0.1% of silicon, 1-2% of yttrium, 0.05-0.15% of calcium, 0.1-0.3% of stainless steel powder, 0.03-0.05% of niobium, 0.3-0.5% of zirconium, 4-6% of aluminium alloy powder and the balance of magnesium. The magnesium alloy effectively improves the processability; and in addition, refinement of grains in magnesium alloy texture is uniform, so that the casting property of magnesium alloy is effectively improved.

Description

technical field [0001] The invention relates to the field of alloys, in particular to a magnesium alloy. Background technique [0002] A composite material is a multiphase material with new properties composed of two or more materials with different properties through physical or chemical methods on a macroscopic (microscopic) level. Various materials learn from each other in terms of performance and produce synergistic effects, so that the comprehensive performance of the composite material is better than that of the original constituent materials to meet various requirements. In recent years, metal matrix composites have been applied in many fields. Metal matrix composites are divided into particle reinforcement, short fiber and whisker reinforcement, and continuous fiber reinforcement according to the reinforcement form. At present, metal matrix composites have achieved relatively great success in iron-based, copper-based, aluminum-based, titanium-based, magnesium-based...
