"Rejuvenating Manufacturing by Integration of Ultrasonic Fields"

This event is sponsored by FAMU-FSU Engineering Department of Industrial & Manufacturing Engineering.

Abstract: Technological demands of the 21st century mandates manufacturing of components with enhanced performance attributes for aerospace, structural, and marine applications. This talk presents recent advancements in manufacturing of metals and their composites by ultrasonic casting. It delves into the interactions of ultrasonic cavitation with reinforcements of systematically varying morphology from 3D spherical, through 2D platelet to 1D tubular. Using specific examples of aluminum matrix composites reinforced with silicon carbide, hexagonal boron nitride and boron nitride nanotubes, this talk establishes the correlations between ultrasonic input parameters, microstructural features, and mechanical properties of these composites. Using this background, the talk prepares a platform for proposed research on high speed visualization for fundamental understanding of cavitation in ultrasonic treated liquid systems. It provides avenues for integrating laboratory-based research knowledge into classroom teaching and service by innovative techniques, instrumentation, and activities.
