A dearth of understanding of the role of ultrasonic treatment parameters on the microstructure, mechanical and tribological properties of 2D material reinforced metal matrix composites severely obstructs the advancement of this technology. This paper presents an analysis of the effect of treatment time on grain refinement, nucleation density, dispersion, and wear resistance of ultrasonic cast 2D tungsten disulfide reinforced aluminum matrix composites. Localized elastic moduli as a function of microstructural features, obtained from nanoindentation is integrated with finite element modelling to compute bulk mechanical properties of these composites. These computations are validated against experimentally measured distributions of elastic moduli of these composites. A comparative evaluation of bulk elastic moduli obtained by three approaches, namely theoretical calculations, microstructural finite element modelling and dynamic mechanical analysis enabled a comprehensive understanding of the processing-microstructure-property correlations in these materials. This constitutes a major step towards the advancement of ultrasonic treatment assisted casting technology.
