Creep Properties of G Tu

Creep-rupture properties of T91 steam generator (SG condition in the stress range 55-150 MPa. At all stres creep rate in the transient creep followed by a minim tertiary creep stage. A systematic decrease in creep tertiary creep. Stress dependence of minimum creep r and rupture life exhibited deviations in terms of lowe at high stresses. A decrease in creep ductility was transgranular at all test conditions. Creep-rupture s reported in literature as well as specified in French Nu
