Abstract
The structure of ZhS6K-VI alloy samples obtained by selective laser melting in a nitrogen atmosphere was studied at a scanning speed of 600, 1000 and 1200 mm/s, as well as after additional heat treatment. The distribution of alloying elements in the structure of synthesized and heat-treated samples, phase composition, morphology, and phase structure were studied by transmission electron microscopy. The effect of scanning speed on the structure of the synthesized material and distribution of alloying elements within the crystallization cells are shown.
