摘要：
Continuous drive friction welding studies on IN718 and SS410 dissimilar combination have been investigated. The influence of friction-welded parameters on microstructure and mechanical properties was dealt in detail. Six different joints were fabricated by varying rotational speed and friction pressure, by keeping forging pressure and friction time as constant. The microstructural study revealed the formation of different zones in the weld region of the dissimilar joint. Tensile and microhardness tests were conducted in order to examine the impact of process parameters of the joint and to define the ideal welding condition. The fractography images exposed the ductile fracture mode for all the samples. The friction-welded joint fabricated with the rotational speed of 1500 rpm and frictional pressure of 189 MPa yielded higher tensile strength and hardness. © 2018, Springer Science+Business Media, LLC, part of Springer Nature and ASM International.
