MAGNESIUM ALLOY MATERIAL AND METHOD FOR MANUFACTURING SAME

摘要

A magnesium alloy material having excellent mechanical characteristics is provided without using special manufacturing equipment nor process. A method for manufacturing such magnesium alloy material is also provided. The magnesium alloy material is an Mg-Zn-RE alloy wherein Zn is included as an essential component, and at least one selected from among Gd, Tb and Tm as RE, and the rest is composed of Mg and an unavoidable impurities. The magnesium alloy material has a needle-like precipitate or a board-like precipitate (lengthy precipitate: X phase=ß phase, ß' phase, ß1 phase).
