The mechanical properties of Ni-based superalloys are based on the hardening γ′-phase which is mainly Ni3Al intermetallic compound with an ordered structure (Ll2). A mathematical model of γ′-phase inclusions growth during direct laser deposition was developed to predict parameters of the hardening p...
