摘要： PROBLEM TO BE SOLVED: To provide an Mg alloy material having superior specific strength and damping performance without using a sintering process. SOLUTION: This manufacturing method includes: cutting an Mg alloy ingot 1 into particles 1a; compacting the particles at room temperature to form a compact 2; extruding the compact 2 at 450°C or lower; and preferably further subjecting the extruded compact to a secondary distortion working step such as backward extrusion, in a temperature range between 250°C and 450°C. The manufacturing method can provide the Mg alloy material having high strength by leaving the distortion of cut particles in the material, without impairing the damping performance. The Mg alloy material with high specific strength can have two or three types of plated layers among an Ni-P plated layer, an Ni-B plated layer and a Cr plated layer formed thereon into a layer form, if desired, and can be preferably used for a structural member in an environment of the deep sea, which is required to have high strength, sound insulating properties and corrosion resistance.
