Abstract
A method for manufacturing a quasicrystal and alumina mixture particles reinforced magnesium matrix composite, includes manufacturing a quasicrystal and alumina mixture particles reinforcement phase, including preparing raw materials for the quasicrystal and alumina mixture particles reinforcement phase including a pure magnesium ingot, a pure zinc ingot, a magnesium-yttrium alloy in which the content of yttrium is 25% by weight, and nanometer alumina particles, the elements having the following proportion by weight 40 parts of magnesium, 50-60 parts of zinc, 5-10 parts of yttrium and 8-20 parts of nanometer alumina particles of which the diameter is 20-30 nm, pretreating the metal raw materials, cutting the pure magnesium ingot, the pure zinc ingot and the magnesium-yttrium alloy into blocks, removing oxides attached on the surface of each metal block, placing the blocks into a resistance furnace to preheat at 180° C. to 200° C., and filtering out the absolute ethyl alcohol after standing, and drying.
