Metal Science and Heat Treatment Aims and scope

Abstract

The methods of electron microscopy, metallography, and determination of impact toughness and resistivity are used to investigate the structural and phase stability of nickel-chromium alloys after aging at 350, 400, and 450°C for up to 40,000 h. The chromium content is shown to be correlated with the susceptibility of the alloys to ordering. It is established that the alloy with about 41 wt.% Cr has the highest stability of the structure and properties in the studied temperature range.
