The method for manufacturing the quasicrystalline phase hardened Mg-based metal alloy comprises the steps of forming a quasicrystalline phase hardened Mg-based metal alloy in which a two-phase region of quasicrystalline phase and metal solid solution exists, and the Mg-based metal alloy comprises Mg-1-10 at.% Zn-0.1-3 at.% Y having hot formability by a casting method; and separating and dispersing the quasicrystalline phase into a matrix by a hot forming to increase strength and elongation of the quasicrystalline phase hardened Mg-based metal alloy, wherein the method further comprises the step of performing high temperature forming at a temperature of about 1/3 or more of melting point when manufacturing final article using the hot formed plate so that the dispersed small quasicrystalline particles are further finely distributed, and the hot forming is performed at a temperature of about 1/2 of the melting point, and volume of the quasicrystalline phase is 30 vol.% or less.
