Abstract: This invention investigates ultrasonic velocities and elastic properties in lead-tin alloys of varying compositions (0–100% Sn) using non-destructive testing. Ultrasonic longitudinal and shear velocities were measured using pulse-echo and interferometry methods. Elastic constants, including Young's modulus, rigidity modulus, and Poisson's ratio, were derived from these velocities. The study reveals a correlation between alloy composition, ultrasonic velocities, and microstructural properties, providing insights into material stability in adverse environments. The experimental setup uses high-purity metals, with measurements confirming the alloys' suitability for aerospace and marine applications due to their stable elastic properties. This invention advances the understanding of Pb-Sn alloys for engineering applications, emphasizing material characterization through ultrasonic.
