摘要

The thermal stability of the austenitic Fe-17%Cr-12%Ni-2%Mo-1%Mn-0.7%Si-0.02%C alloy, produced by selective laser melting, was investigated. It is shown that the cellular structure is retained in the alloy up to 800℃. With further increase in the annealing temperature, the dislocation structure of the alloy changes (800-950°) and the solid solution supersaturated with atmosphere atoms decomposes (1050-1150°).
