Description

technical field [0001] The invention belongs to the field of heat-resistant magnesium alloy materials, in particular to a nano-particle reinforced multi-element heat-resistant magnesium alloy and a preparation method thereof. Background technique [0002] As the lightest commercial metal engineering structural material, magnesium alloy is known as the "21st century" because of its light specific gravity, high specific strength and specific stiffness, strong damping and vibration reduction, excellent liquid forming performance and easy recycling. Green Structural Materials". However, at present, due to the poor high-temperature creep resistance of existing magnesium alloys, the long-term working temperature cannot exceed 120°C, making it impossible to be used in the manufacture of automotive engines and other transmission parts that require high-temperature creep performance, thus greatly hindering the development of magnesium alloys. Further applications of the alloy. It i...
