Feedstock Modification and Microstructural Characterization of Cold Spraying of Inconel 718 Free

This research aims to enhance the deformability of Inconel 718 by modifying the feedstock microstructures prior to deposition through solution treatment process at 950 °C and 1050 °C. It was observed that the gamma phase has transformed into a stable delta precipitate at 950 °C. Higher treatment temperature at 1050 °C shows a complete solution transition, proven by EBSD phase map, and electron channelling contrast imaging (ECCI).
