Abstract
Thermal-deformation conditions of formation of friction welded joints on heat-resistant nickel alloy EI698VD were estimated. The possibility of reaching the melting point of the heat-resistant alloy within the contact zone at a stage of heating was proved, and behaviour of the melt at all stages of the process was studied. Methods for optimisation of the technology of friction welding of heat-resistant nickel alloys, and methods for minimisation of width of the phase transformation zone in welded joints were suggested.
