N2 - The degradation process of the micro texture of Ni-base superalloys was observed under fatigue and creep-fatigue loading conditions by applying electron back-scatter diffraction (EBSD) analyses. It was found that the crystallinity of grain boundaries degraded seriously under creep-fatigue loading conditions. This degradation was found to cause the drastic decrease of the strength of grain boundaries and thus, lifetime of the material.
