抄録

2024 aluminum alloys naturally aged, artificially aged and annealed were friction welded using a brake type friction welding machine. The hardness distribution of both naturally and artificially aged friction welded joints showed that the softened areas existed at the heat affected zone. Regardless of the preheat-treatment, maximum tensile strength and elongation of the friction welded joints were obtained when friction time was 2 seconds, but they were lower than those of the base metals. All the impact specimens with the notch into the weld interface showed impact strength inferior to that of the base metals. This tendency was remarkable for the artificially aged friction welded joint. The fatigue specimens of both naturally and artificially aged friction welded joints showed lower fatigue strength than that of the base metal, but fatigue strength of the annealed friction welded joint was slightly higher than that of the base metal. Fatigue strength of both artificially and annealed friction welded joints showed slightly lower than that of the naturally aged friction welded joint.
