Abstract

Fractographic investigation of Co–Cr–Ni–W–Ta alloy samples obtained by selective laser melting and having horizontal and vertical orientation on a build platform is performed. The samples underwent hot isostatic pressing. The microstructure near the fractures was investigated and type of destruction and porosity were determined. The dependence of the samples orientation on their rupture character is investigated. All samples exhibit viscous rupture during long-term strength test.
