摘要: Modern nickel-base superalloys, which contain a high volume fraction of hard cubical {gamma}{prime} precipitates embedded coherently in softer {gamma} matrix, are used as turbine blade material due to their good resistance creep deformation at temperature. In this present study, the authors will analyze relationship between steady-state rate and applied stress DZ17G, modern DS cast superalloy for producing blades vanes aeroengine applications. On basis TEM observations calculations threshold different mechanism, finally propose mechanism DZ17G
