In the structure of the samples manufactured by the additive method of selective laser melting (SLM) of the Fe-based powder, particles were detected with a minimum size of 0.15 ± 0.05 μm, which were interpreted as germ objects of solidification. The model of additive samples hardening by nanoparticles was proposed, which were formed in the process of desublimations (condensation of metal vapors + crystallization) in the sequence: Metastable state to Segregation to Cluster to Nano-object.
