Manufacturing method of particle-distributed wrought magnesium alloys and wrought magnesium alloys thereby

摘要

The present invention effectively applies a second phase or multi-phase to a magnesium matrix through hot extrusion and / or hot rolling of a magnesium alloy cast material containing a volume fraction of 5% to 50% of a phase other than magnesium. The present invention relates to a method for producing a particle-dispersed magnesium alloy workpiece obtained by granulating and minimizing a known grain, and a magnesium alloy workpiece produced thereby.;According to the present invention, the method for producing a dispersed magnesium alloy workpiece is Al, Si, Ag, Ca, Ni, Cu, Zn, Y, Sn, La, Ce, Pr, Nd, La At least one of rich-misch metal, Ce rich-misch metal, and Didymium rich-misch metal is mixed and cast with magnesium, whereby elements other than the magnesium are contained in the magnesium matrix in a volume fraction of 5% to 50%. Making magnesium alloy castings; And hot-extruding the cast material to refine the grains through granulation, dispersion, and recrystallization of phases other than magnesium in the cast material.;Magnesium alloy, particle dispersion, hot extrusion, hot rolling, grain refinement, superplasticity.
