Document Type and Number:
Japanese Patent JP6731601
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a joint method of flame-retardant magnesium alloy capable of stably obtaining a joint having a high joint strength and preferable elongation.SOLUTION: A joint method of magnesium alloy is characterized in that, in regard to a method of arranging an upper tool and a lower tool so as to oppose to each other on the surface side and the back surface side of a part to be joined between a first material to be joined and a second material to be joined and subjecting the first material to be joined and the second material to be joined to friction stir welding, at least one side of the first material to be joined and the second material to be joined is turned into a flame-retardant magnesium alloy in which calcium of 0.5 to 12.0 wt.% is added to the magnesium alloy.SELECTED DRAWING: Figure 1
