Title:
A Magnesium alloy member and a manufacturing method for the same
Document Type and Number:
Japanese Patent JP5948124
Kind Code:
B2
Abstract:
A high-strength magnesium alloy member is suitable for products in which at least one of bending stress and twisting stress primarily acts. The member has required elongation and 0.2 % proof stress, whereby strength and formability are superior, and has higher strength and large compressive residual stress in the vicinity of the surface of a wire rod. In the magnesium alloy member formed as a wire rod in which at least one of bending stress and twisting stress primarily acts, the wire rod includes a surface portion having the highest hardness of 170 HV or more in the vicinity of the surface and an inner portion having a 0.2 % proof stress of 550 MPa or more and an elongation of 5 % or more, and the wire rod has the highest compressive residue stress in the vicinity of the surface of 50 MPa or more.
