During selection of filler materials for 3D deposition additive technologies, it is important to clarify the deformation capacity of multilayer-deposited metal in its 'as-built' structural state, which in its turn is suggested to be correlated with experimental data on ensuring or not ensuring the technological strength of corresponding products. A testing method of nickel alloys planned for applied application in 3D deposition technologies is proposed and based on conducting evaluation mechanical tests for multilayer-deposited metal, including longitudinal tensile tests (20, 1000, 1100°C), static and impact bending tests (20°C). This method is approved by testing on 14 types of wire- and powder-based filler material. Corresponding deposited metal of Hastelloy C22, Inconel 625, ЭП648, ЧC40, Inconel 718, Inconel 939, Rene 80, Inconel 738LC, ЖC6C, ЖC6C, ЖC32 nickel alloys is obtained by multilayer arc-welding deposition of 'vertical wall'-type workpieces. Two technological factors affecting deformational capacity of nickel-alloy-deposited metal in 'as-built' structural state have been exposed: the chemical composition by criteria of Al, Ti, Nb, Ta, W main alloying-elements' content, which, given their certain amount, are capable of forming γC-phase precipitate hardening; average weight content of oxygen and nitrogen. Based on the obtained experimental data on critical deformation ε, maximum bend angle before cracking β and impact strength KCU values, it is proposed to divide the nickel- alloy-deposited metal into three groups, which correlate with the possibility to provide technological strength at the current level of beam and arc 3D deposition technological development.
