Abstract:
A subframe structure includes a frame front part and a frame rear part in a vehicle front-rear direction. The frame front part and the frame rear part are joined together. The frame front part has a higher strength than the frame rear part. The subframe has different strengths from part to part. The frame front part is made of a galvannealed steel plate (GA steel plate) subjected to an electrodeposition coating. The frame rear part is made of a hot-dip galvanized steel plate (GI steel plate) subjected to an electrodeposition coating. A rear cross member of an aluminum die-casting and a rear cross panel of a hot-dip galvanized steel plate (GI steel plate) are integrally joined together by a friction stir welding.

Claim (Index 1):
A different materials joint structure comprising:\n different materials of an iron member and an aluminum member integrally joined together by a friction stir welding; wherein the different materials joint structure is a subframe mounted on a vehicle, wherein the subframe comprises a frame front part and a frame rear part in a vehicle front-rear direction, wherein the frame front part and the frame rear part are joined together, wherein the frame front part has a higher strength than the frame rear part, wherein the subframe has different strengths from part to part, and wherein surface treatment of the iron member differs between the frame front part and the frame rear part.
