Prediction of Microstructure Evolution of Cold Sprayed Coatings Using a Dislocation Density Based Constitutive Model. Proceedings of the 2nd International Conference on Advanced Surface Enhancement (INCASE 2021), 125–128. https://doi.org/10.1007/978-981-16-5763-4_27
A dislocation density based model is implemented as a user hardening subroutine in Abaqus within the Eulerian finite element framework to predict the Geometrically Necessary Dislocations (GND) density and grain refinement during the cold spray deposition process of Al6061-T6. The model is capable of exploring the dependency of the microstructure on the cold spray process parameters such as particle velocity, deposition angle, initial temperature and particle size. Furthermore, the model depicts microstructural evolution in critical regions such as the coating-substrate interface and particle boundary and provides insights into the microstructural distribution observed at different locations in a cold sprayed part.
