Factors of strength increasing of metals produced by selective laser melting of powders
https://doi.org/10.22349/1994-6716-2018-95-3-68-75
Abstract
Standard samples of metal powders of various chemical composition were made for mechanical tests by selective laser melting. The paper describes an increase in strength characteristics of all samples made by melting comparing with similar parameters of monolithic samples of identical chemical composition. It is established that ultrafine-grained structure and condensation of nanoparticles could be cosidered factors of strength increase.
