摘要： Disclosed is a quasicrystalline phase-reinforced Mg-based metallic alloy with high warm and hot formability, and making method thereof. The metallic alloy comprises a composition of Mg—1˜10 at % Zn—0.1˜3 at % Y, in which a two-phase region consisting of a quascrystalline phase and a magnesium-based solid solution phase exists. Constituting a matrix structure, the Mg-based solid solution phase (&agr;—Mg) is formed as a primary solid phase upon solidification. The quasicrystalline phase serves as a second phase and forms, together with the Mg-based solid solution phase, a eutectic phase, thereby reinforcing the matrix. The materials obtained through the hot rolling or extrusion of the cast alloy have an increased volume % of the second phase and thus show significantly increased strength.

摘要： Disclosed is a method of manufacturing a metal matrix composite in which oxide nanoparticles are dispersed. Metal matrix composite powders in which oxide nanoparticles are dispersed are prepared. Gibbs free energy of the oxide nanoparticles is greater than that of an oxide of a metal matrix. A bulk processed material is manufactured from the composite powders through hot forming or a cast material is manufactured by inputting the composite powder into a molten base metal and then rapidly stirring a resultant mixture. The bulk processed material or the cast material is heat-treated so that atoms of the metal matrix and atoms of the oxide nanoparticles mutually diffuse. Oxygen atoms originating from the oxide nanoparticles are diffused and dispersed in the metal matrix.
