Abstract

In this work, the evolution of the microstructure, phase composition and crystal structure of 3D products before and after heat treatment, obtained from the original steel 12Cr18Ni10Ti by various metallurgical methods of melting, was studied. The obtained 3D steel samples were subjected to heat treatment, then structural changes were investigated by metallography, X-ray phase (XRD) and X-ray structure (XRD) analyzes. The analysis showed that heat treatment did not increase the grain size of austenite in additive steels, but could lead to an increase in the proportion of ferrite.
