Chromium- and nickel based alloys offer good mechanical properties, while keeping them also in highly corrosive environment. In addition, the introduction of the nitrogen at the level of 0.3 to 0.5% to the alloy structure, increases the plastic deformation ability of the cast alloy. This observation is fully confirmed by the results of the plastic deformation tests (performed on Gleeble), which are presented in this paper. The laboratory samples made of NiCrN wrought alloy and processed by die forging, demonstrated the significant increase of the yield stress and plastic deformation ability for the applied deformation degrees. The experiments showed about twofold increase of the resistance to cyclic loading for the forged products, when comparing it to the initial alloy state after casting. The developed technology (validated by numerical simulations) has been used to manufacture the workpiece for the propeller shaft. The results of the deformation performance for the element subjected to plastic processing have been compared with the material in its cast state.
