Abstract The paper discusses the influence of prolonged operational time on structural and phase composition of industrial nickel ZMI-3U and IN738LC superalloys and on dynamics of transient mechanical properties of the materials at various temperatures. A mathematical dependence has been established for estimation of strength and plastic properties of materials with respect to the operating time (life time).
