Abstract
A reinforced magnesium matrix composite includes a quasicrystal and alumina mixture particles reinforcement phase and a magnesium alloy matrix, where the weight ratio of the quasicrystal and alumina mixture particles reinforcement phase to the magnesium alloy matrix is (4-8) to 100; the magnesium alloy matrix including by weight 1000 parts of magnesium, 90 parts of aluminum, 10 parts of zinc, 1.5-5 parts of manganese, 0.5-1 part of silicon and 0.1-0.5 part of calcium; the quasicrystal and alumina mixture particles reinforcement phase including 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; and the quasicrystal and alumina mixture particles reinforcement phase having a size of 100-200 mesh.
