STEEL MATERIAL FOR DISSIMILAR METAL JOINING, JOINED BODY OF DISSIMILAR METALS AND PROCESS FOR JOINING DISSIMILAR METAL MATERIALS |
摘要 |
A joined body of dissimilar metals which is produced by joining a steel material and an aluminum alloy material, wherein the steel material to be joined has a specific composition and is specified in the compositions of outer surface oxide layer and inner oxide layer and the aluminum alloy material to be joined is an Al—Mg-base or Al—Zn—Mg-base aluminum alloy having a specific composition. In the joined body of dissimilar metals, a content of Fe at a joint interface on the aluminum alloy material side is regulated, and a reaction layer of Fe and Al is formed at the joint interface of the joined body of dissimilar metals. The joined body of dissimilar metals exhibits high joint strength. |
