Abstract

Both the ultrafine-grained (UFG) structure with a grain size (d) less than 1 mm and nanocrystalline (NC) structure (d £ 100 нм) can be processed in nickel-based alloy 58Ni-Cr-Mo-B-Al-Cu using methods severe plastic deformation, in particular, multistep isothermal forging within the temperature range of g+δ - region on Bridgman anvils at strains е=5,5. Pressure welding  performed under conditions of low temperature superplasticity  (T=800оС, έ=10-4с-1) can provide solid state joining of the alloy under study being  in different structure conditions as well as joining of samples with coarse-grained structure using a NC layer.
