| Abstract Scope |
Ultrasonic casting has recently emerged as a promising technique for manufacturing metal matrix composites that exhibit high strength, wear resistance while being lightweight. However, an absence of understanding of the interaction between ultrasonic process parameters and the morphology of reinforcement particles severely impedes casting high performance composites. This paper presents comprehensive correlations between ultrasonic processing and dispersion of 3D, 2D, and 1D reinforcements in aluminum matrix composites. The effect of dispersion on multiscale mechanical properties are delineated by quasi-static nanoindentation, dynamic modulus mapping and finite element modeling. This new scientific knowledge about the interrelatedness between ultrasonic processing, reinforcement material morphology, and composite performance is thus a significant advancement to the current state of the art in metal matrix composite manufacturing technologies. |
