Original Abstract

Cylindrical specimens of Inconel 713LC in as-received condition and with surface treatment by Al-Si diffusion coating were cyclically strained under strain control at 800 degC in air. Changes in the shape and size of the superalloy precipitates during the surface treatment are documented. The structural and hardness characteristics of the hardened surface layer are presented. Hardening/softening curves, cyclic stress-strain curves, and fatigue life curves are obtained. The sections parallel to the specimen axis and fracture surfaces have been examined to study fatigue damage mechanisms. The coating results in fatigue life improvement while the stress response of the treated material is lower in comparison with the untreated one.
