| Abstract Scope |
Acoustoplasticity uses high-intensity acoustic/ultrasonic waves to deform structures. This has been successfully used in Ultrasonic Additive Manufacturing and ultrasonic welding of metallic structures. The objective of this article is to understand the mechanics of acoustoplasticity and the effect of processing parameters such as speed, power, and downforce on the resulting microstructures. Multiple combinations of the processing parameters were used to create a test matrix of samples, which were further characterized using SEM, EBSD, and low-amplitude acoustic wave testing. Also, a micro-hardness test was performed on the samples to see the effect of acoustoplastic deformation. The ultrasonically deformed regions show very small-grained structure, and the degree of deformation varied with processing parameters. Lastly, the surface roughness value analyses showed that increasing of acoustic energy increased the roughness of the surfaces. |
