Nanomechanical effect of particle size, coherency, and volume fraction (a) The immersion mode high-magnification BSE images captured near melt pool boundary, (b, c) STEM-EDS maps show variations in particle composition and volume fraction within the pool boundary, (d, e) high magnification TEM reveals variation in dislocation pattern in particle rich and depleted grains (f, g) nanoindentation P–h curves captures the nanomechanical impact of such heterogeneity in particle distribution, and (g) schematics illustrate two possible particle-indenter interactions depending on the local particle size.
