6061 aluminium alloy matrix composite containing 20.5 vol% particulate alumina and 5052 aluminium alloy were welded using a brake type friction welding machine. The microstructures and mechanical properties of the friction welded joints were investigated. The mechanically mixed regions and the alumina particles which had moved to the other part of the composite alloy were observed clearly on the weld interface. The hardness at the weld interface showed higher values than those of the base metals. The variation of hardness on the composite material side was not very significant, but a softened area could be seen in the heat affected zone of the 5052 aluminium alloy side and recovery to the same level of hardness as that of the 5052 aluminium alloy base metal could be found at about 20 mm from the weld interface. Regardless of the welding conditions, the joint efficiency in terms of tensile strength was 95–101% of that of the composite material base metal and the maximum elongation was 71% of that of the composite material base metal. Friction welded joints with good joint efficiency fractured near the weld interface of the heat affected zone of the composite base metal. The impact values of the welded joints with a notch in the weld interface were about 70% of those of the composite material base metal.

Friction Pressure

In this work, pipe billets with a diameter of 73 mm and a wall thickness of 9 mm from steels 32G2 and 40KhN are friction welded with an aim to optimize the process parameters. The friction pressure, the forging pressure and the length of the fusion varied. After the implementation of various welding modes, tensile tests and metallographic studies were carried out. The optimal welding parameters have been established, which make it possible to obtain tensile strength at the level of the 32G2 base metal. The study results of the microstructure and SEM fractographs after the optimal welding mode are presented.
