Abstract Scope |
In this paper, we report the calculation of the elastic constants such Poisson’s ratio, elastic modulus and shear modulus deduced from the ultrasonic propagating equations with two types of ultrasonic vibrations named longitudinal and transverse waves. The ultrasonic propagating velocity is measured at the microstructural evolution in a Ti-6Al-4V medical alloy with two varying microstructures, bimodal and acicular respectively. The two different initial microstructures were treated thermally by aging at 515°C, 545°C and 575°C at different times from 1 min to 576 hrs to induce a precipitation process. Ultrasonic measurements of shear and longitudinal wave velocities, scanning electron microscopy (SEM) image processing and micro hardness were performed, establishing a direct correlation with the measurements of the ultrasonic velocity and the elastic properties developed during the thermal treatment of the artificial aging. |
