Presentation Title Ultrasonic Energy Enabled Dynamic Recovery in Aluminium during Micro Forming and Its Effects on Stress and Microstructure Evolution
Author(s) Anagh Deshpande, Keng Hsu
On-Site Speaker (Planned) Anagh Deshpande
Abstract Scope The phenomenon of ultrasonic softening has been used in manufacturing processes like forming, drawing, wire bonding and more recently, additive manufacturing to take advantage of the reduced yield stress of metals under the influence of ultrasonic irradiation. In the micro forming experiments that will be described in this talk, evidence of ultrasonic energy enabled dynamic recovery in pure aluminium, similar to that during hot deformation, has been observed. This ultrasonic energy enabled dynamic recovery affects the microstructure and stress evolution during deformation. Based on this observed dynamic recovery, Kocks-Mecking model has been modified to predict the stress evolution during uniaxial compression tests. In this talk, an evidence for ultrasonic energy enabled dynamic recovery will be presented along with a comparison of experimental and predicted stress evolution, which can further the understanding of the use of ultrasonic softening in manufacturing processes.
