摘要：
The inertia friction welding behavior of similar (LSHR to LSHR or Mar-M247 to Mar-M247) and dissimilar (LSHR to Mar-M247) alloy pairs was determined. The relationships between the IFW process parameters and welding response, such as the kinetics and efficiency of the transformation of the mechanical energy of the flywheel into heat of joining samples, weld duration, kinetics of flash formation, and bond quality were identified. Conditions resulting in sound welding were determined. It was found that the mechanistic behavior of each of the alloys during dissimilar welding can be approximated by the behavior of the respective alloy during similar welding. By contrast, the microstructure, microhardness and the thickness of the heat affected zone depended on the type of the alloy pair used during IFW.
