Abstract

Additive manufacturing is increasingly used in the aviation industry. Its main feature is the manufacture of parts of complex external and internal geometric shapes without increasing the cost of their production. To calculate the resource of nodes and reliable operation of new equipment, it is necessary to have a set of calculated values of characteristics of structural strength, including the characteristics of tensile, creep rupture and high-cycle fatigue (HCF). The study of characteristics of tensile, creep rupture and HCF of the Co–Cr–Ni–W–Ta alloy obtained by the method of selective laser melting (SLM) is presented in this paper.
