Abstract:
A method of making a quasicrystalline phase-reinforced magnesium-based metallic alloy, comprising the steps of:casting a quasicrystalline phase-reinforced magnesium-based metallic alloy consisting of 1-10 at % Zn, 0.1-3 at % Y, and the remainder Mg into a mass, in which a two-phase region consisting of a quasicrystalline phase and a metal solid solution phase exists; and warm or hot forming the mass to separate and disperse quasicrystalline particles throughout the matrix, so as to provide the quasicrystalline phase-reinforced magnesium-based metallic alloy with improved strength and elongation.
