Influence of coherence violation on growth of γ′-phase particles in heat-resistant nickel alloys

Аннотация

Comparative structural analysis of a heat-resistant Ni alloy containing Re and Ru after complete thermal treatment (CTT) and grip sections after high-temperature creep test is presented in the article. It is shown that, after CTT and after long term annealing (from 500 to 1210 h) within the temperature interval from 900 to 1150°C, the size of the γ′-phase particles hardly changes. The article explains the size stabilization of the γ′-phase particles.
