Resumo
Standard samples for mechanical tests have been produced by selective laser melting (SLM) of metal powders of various chemical compositions. It has been determined that strength properties of all SLM samples are higher than those of solid samples of the same chemical composition. It has been established that the factors of strength improvement are vapor condensed nanoparticles above the melting zone and ultrafine grain structure formed at the stage of crystallization.
