Numerical analysis of plastic behavior anisotropy of additively manufactured IN939 superalloy subjected to cyclic loading at high temperatures

Popis výsledku v původním jazyce

The Inconel IN939 superalloy is a suitable material for additive manufacturing. However, such a manufacturing process creates an anisotropic microstructure, which influences the material’s mechanical performance. The effect of microstructure on fatigue behavior at high temperatures is studied using the finite element method within the crystal plasticity framework. The spatial evolution of stresses and strains with cyclic loading is analyzed. The results show that material loaded perpendicularly to the building direction (BD) has higher strengthening and higher activity of slip systems in whole volume while loading parallel to the BD induces plasticity, preferably in grains with (101) and (111) orientation. Such differences can lead to different damage initiation and evolution.
