Effect of Friction Time on Microstructure and Mechanical Properties of Friction Welded AISI 304 Stainless Steel to AISI 1060 Steel

摘要

The influence of friction time on the hardness, tensile properties, and microstructure of the welded samples is investigated. With increasing friction time, the hardness and tensile strength values increase too. The hardness of the welding interfaces is higher than that of the base alloys. Microstructures of the welds are examined by the optical and scanning electron microscopy. The results show that all welding joints are perfectly bonded and free of any cracks, pores, and defects. The tensile fracture of welded joint occurred in the AISI 304 side. The chemical composition of the interfaces and deformation zones are detected using energy dispersive spectroscopy. Diffusion of the Cr and Ni is evident on the AISI 1060 side.
