详细
Experiments on solid-phase pressure welding (PW) of a wrought EP975 nickel superalloy with a Ni3Al-based VKNA-25mono intermetallic alloy in a single-crystal state are performed under the superplasticity of the EP975 alloy, where its deformation was 24%. The structure and the phase composition of the interaction zone that forms between the materials to be joined after PW and PW followed by heat treatment are studied. The mechanical properties of the welded samples with a solid-phase joint are investigated. The ultimate tensile strength of the welded samples is shown to be 0.76 of the strength of the VKNA-25 alloy.
