Heat Resistance and Physicochemical Properties of Multicomponent Nickel Alloys (Zharoprochnost i Fiziko-Khimicheskie Mnogokomponentnykh Nikelevykh Splavov),
Abstract
A study was made of the change of some physicochemical properties in alloys with a nickel base, beginning with two-component and ending with eight-component alloys. It is clear from an electron microscope analysis that a complication of the composition of the investigated alloys results in a decrease in the excess Gamma-phase, its more uniform distribution in the alloy and a greater uniformity throughout. The results of an x-ray spectral microanalysis indicated that the chemical composition of the Gamma-solid solution and the Gamma-phase is complicated by the introduction of additional components in the alloy. High-temperature electric resistivity increases with an increase in the aluminum content in the alloys, as well as with a complication of their composition. The linear coefficient of thermal expansion of alloys decreases with a transition from the less complex alloys to those with a greater number of components. (Author)
