Influence Principle of Ultrasonic Vibration on the Rheological Behavior of Materials

Abstract:

An experiment equipment for indentation test on the partial material was designed, which was acted by ultrasonic coupling with the pressure load. In the pressing experiment, the 7050 aluminum alloy and Hastelloy C-276 nickel-based alloy were chosen, and the effect principle and mechanism of energy transmission of ultrasonic vibration pressing on the rheological behavior of the single point of the material were studied. The results show that, ultrasonic energy can reduce the load and promote the efficiency for the plastic deformation process of material, which is performed by a single point load. This work declares that, when ultrasonic field is added to the partial rheological interface, the metal in the deformation zone slides in the form of pulses. Meanwhile, the grains of sliding material perform a resonance response, which is encouraged by the sliding pulse, and the high energy shortwave phonon generated. It spread to the high density dislocation crystal boundary in the deformation zone, leading the energy jump of those grains. Finally, this energy is translated into the plastic distortion energy of the metal.
