Abstract

Treatment of materials using selective laser melting technology allows obtaining different products from a wide range of metallic materials. Aluminum powders allow also manufacturing construction elements. Achieving required strength of many aluminum alloys depends on applied heat treatment. The article presents investigation results of heat treatment parameters influence on tensile strength characteristics as well as the results of fractographic research. The work is carried out under the realization of integrated research area 10.3. «Technologies of atomization for producing high quality metallic powders for additive manufacturing and powders for brazing» («The strategic directions of development of materials and technologies for their processing for the period till 2030»)
