Abstract
The high temperature low-cycle fatigue (HTLCF) behaviour of the recent ly developed oxide dispersion strengthened (ODS) alloy PM 1000 is inve stigated at 1123 K using total strain controlled symmetrical wave shap es (R = -1). In order to reveal the influence of grain structure and t exture (a) a [100]-fibre structured bar material with a grain aspect r atio (GAR) of 10 along the longitudinal direction and (b) a pancake st ructured sheet material with a GAR of 4 and [100]{011} been studied. T he grain structure determines the fracture path, but cannot be correla ted with the cyclic lifetimes. Instead, lifetime can be predicted on t he basis of the different Young's moduli of the grain structures. (C) 1997 Elsevier Science S.A.
