抄録

A 6061 aluminum alloy was joined to a 304 stainless steel by friction welding. The structure of aluminum alloy was refined in the vicinity of the weld interface. However, the Vickers hardness was decreased near the interface since the precipitates were dissolved in the aluminum alloy matrix by the friction heat. The width of heat affected zone (HAZ) was decreased as the increase in the friction and upset pressure (P₁ and P₂) increased. The sound joints were obtained welded by P₁ =30 MPa, P₂ =60 MPa and t₁ (friction time) ≥2.0 s. The higher P₁ made the joint strength decrease owing to the excess formation of brittle intermetallic compounds at the weld interface. The inter-diffusion of each element through the weld interface were revealed using TEM–EDS analysis. Fe₂Al₅ was mainly formed at the weld interface. The welding temperature was estimated to be under the eutectic temperature of Al/Fe system(925 K) by the thickness of intermetallic compound. Therefore, it is assumed that this friction welding was carried out in solid state in this system.
