Original Abstract

Dislocation structure was studied in polycrystalline superalloy INCONEL 713 LC cyclically strained under strain control with constant total strain amplitude up to failure at 23, 500, 700 and 800 °C. Thin oriented foils were studied in transmission electron microscope equipped with double tilt holder. Inhomogeneous dislocation microstructure was documented at all four temperatures. Dislocations were present both in the matrix and in the gama` precipitates. Higher dislocation density was in the matrix. Planar slip bands parallel to the {111} planes were observed at room and high temperatures. The slip bands were present at thin slabs of high dislocation density cutting both the gama channels and gama` particles.

Key words in English

Superalloz, Inconel 713 LC, dislocation microstructure, fatigue
