Abstract Keywords
The study tested the thermal stability of the austenitic alloy
Fe — 17 % Cr — 12 % Ni — 2 % Mo — 1 % Mn — 0.7 %
Si — 0.02 % C, obtained by selective laser melting. In our
research we applied methods of metallographic analysis,
as well as scanning and transmission electron microscopy.
It is shown that cellular structure is retained in the alloy
up to 800 C. With further increase in the annealing tem-
perature, the dislocation structure of the alloy is changed
(800 ÷ 950 C) and the supersaturated with atmosphere
atoms -solid solution decomposes (1050 ÷1150 C)
