| Abstract Scope |
It was found that subtle changes in the thermal histories of the alloy Ti-5553 exhibited a significant influence on velocities of longitudinal, shear, and surface acoustic waves (SAWs). In addition, variations in the alpha precipitates resulted in remarkable differences in the attenuation of the longitudinal acoustic waves, as well as observable differences in surface acoustic waves measured using different approaches. These acoustic results are correlated materials state using a variety of electron-optical techniques across length scales, and limited indentation methods where appropriate. Taken together, these results indicate that microstructural features that cannot be directly measured using acoustic approaches have unexpectedly strong effects on materials properties including measurable differences on the acoustic waves. These results are important to both the materials science and nondestructive evaluation communities. |
