Samples cut from a disk blank of Russian granulated nickel-based superalloy VZH178P were tested for tensile strength at room temperature and long-term creep at temperature of 750 °C. Transmission electron microscopy showed that, in both cases, stacking faults and microtwins formed during plastic deformation of the alloy. During long-term creep at 750 °C, the alloying elements Cr, Co, Mo, and W segregate on the stacking faults, leading first to the formation of Suzuki atmospheres and then to the nucleation and growth of TCP particles with stoichiometry (Co,Cr)3(Mo,W).
