| Abstract(in English) | The line-focus-beam ultrasonic material characterization (LFB-UMC) system is applied to evaluation of commercial Pyrex glasses (C-7740, Coming Inc.). Twenty-eight specimens were prepared at random from different lots. Leaky surface acoustic wave and leaky surface-skimming compressional wave velocities were obtained through the. measurements of V(z) curves at 225 MHz around 23℃. The differences in the acoustic properties must be related to the different chemical compositions or the different thermal histories in the fabrication processes. In order to investigate the differences of leaky acoustic wave velocities, bulk acoustic properties, viz., longitudinal and shear velocities, and density, were measured around 23℃ for eight specimens extracted from the twenty-eight specimens. All the bulk acoustic properties were changed as well as leaky acoustic wave velocities. Thus, we demonstrated that the LFB-UMC system is very useful and effective for evaluation of glasses and control of the production processes. |
