Abstract

This review analyzes the influence of alloying elements on the mechanical properties of granulated high-temperature nickel alloys. It is shown that the introduction of alloying elements such as Al, Ti, W, Mo, Nb, Ta, and Hf into the alloys contributes to material strengthening. Alloying with γ-forming elements such as Co and Cr leads to an increased creep resistance at temperatures up to 750 °C and heat resistance. A small content of microalloying elements such as B and Zr also has a positive effect on ductility.
