Patent ID: 8820614

Claim:
A method of producing a magnesium alloy joined part, the method comprising steps of: joining at least one member selected from group consisting of a reinforcing material, a boss, and a pin, all made of metal, to a rolled plate comprised of a magnesium alloy without allowing an organic material to remain at the joined portion; and performing plastic working on the rolled plate having undergone the joining step in a temperature range of 150° C. to 300° C., wherein the joining is performed by forming a joining layer, and the joining layer comprises an inorganic material and does not include organic material, wherein a difference in a thermal expansion coefficient between the reinforcing material and the roller plate is between 0.4×10 −6 /K and 10×10 −6 /K, and wherein the inorganic material includes an adhesive comprising at least one member selected from the group consisting of an oxide of Al and an oxide of Si.
