Study of formation of intermetallic matrix structure based on heat-resistant nickel alloys

Serpova V.M., Grishina O.I.
Abstract

The paper presents the results of a study of the structure formation of in-thermetallide-oxide high-temperature metal composite materials based on nickel alloys reinforced with monocrystalline aluminum oxide plastids. Samples for research were obtained by the method of reaction impregnation. nickel powder with a diameter of 5–10 µm and nanosized nickel alumina particles with a diameter of 1–10 nm were used as matrix-forming agents. The results of the study of the microstructure and phase composition of samples of metal composite materials with different NiAl particle content (10; 15 and 20%) are shown. In order to identify individual intermetallic phases, microhardness studies were conducted.

Keywords
metal-matrix composite, intermetallic composites, nickel intermetallic, x-ray diffractometry, scanning electron microscopy.
