Effect of the regimes of selective laser melting on the structure and physicomechanical properties of cobalt-base superalloys

In this article, we give a preferential regime of selective laser melting for the production of parts from a cobalt superalloy using a PTK-PS domestic machine, which can find application upon the production of components from various superalloys in the aviation and atomic industry and in the automobile industry. We have investigated the phase composition and determined the physicomechanical properties of the samples prepared under the preferential regime of selective laser melting. It has been established that the structure of the alloy obtained by selective laser melting consists of two supersaturated solid solutions based on the low-temperature hexagonal and high-temperature cubic cobalt modifications, which leads to an increase in the strength characteristics of the samples in comparison with the cast samples.
