Abstract

Abstract

Cyclic creep tests were conducted in an iron-base superalloy GH132 at 650℃ and constant maximum stress （46kg/mm²） with different minimum stresses（10,23 and 43kg/mm²）. Deformation at cyclic creep is complicated. Beside elastic and plastic deformation, an elastic deformation occurs at cyclic creep. Deformation behaviour at cyclic creep depends on stress amplitudes and minimum stresses.
