Regularities of the formation of structure, phase composition and tribological properties of heat-resistant chromium-nickel alloys «Nikorin»

In this work, new solutions have been obtained for a scientific and practical problem, which consists in increasing the complex of tribological properties and heat resistance of chromium-nickel alloys for modern mechanical engineering. The composition of heat-resistant chromium-nickel alloys is investigated. The distribution of alloying elements between phases and structural components is studied, the dependence of the change in mechanical properties on the parameters of the structure and phase composition is established.

Calorimetric analysis of the alloys under study during heating/cooling is carried out. The crystallization/melting temperatures of the nickel-chromium alloy «Nikorin» were determined. The structure, phase composition, microhardness of the structural components of the heat-resistant chromium-nickel alloy «Nikorin» after quenching from various temperatures have been studied. The tribological properties of chromium-nickel alloys in the cast state are investigated.
