SEM micrographs of the fractured surface before and after the W-NPs impregnation process. (a) Fractured surface as-received. (b) Sonicated fracture with W-NPs. (c) Interaction of W-NPs with the Inconel 725 annealed at 1150°C for 2 h. (d) A zoom of the area depicted in (c) shows prismatic crystals with nanowhisker growth on the surface.
