We have determined the nonlinear ultrasonic parameter β and the ultrasonic longitudinal phase velocity vL for a series of martensitic steel specimens which varied in carbon content. The specimens were measured in the as-quenched state to ensure that

Ionization cross sections differential in the angle and energy of the detected electrons were measured for electron impact on hydrogen gas at 200, 500, 1000, and 1500 eV. Measurements were made from 15\ifmmode^\circ\else\textdegree\fi{}--150\ifmmode^

The objective of this study was to examine the relationship between the longitudinal and transverse velocities of ultrasound and the microstructure of martensitic steel, which changes due to the tempering process. The hardness of a material is determ

We have investigated the effect of carbon content on the nonlinear ultrasonic parameter β and the longitudinal phase velocity v L in a series of martensitic steel specimens. The specimens were measured in the as-quenched state to insure that the car

For several years we have used Resonant Ultrasonic Spectroscopy (RUS) for routine determination of elastic-stiffness coefficients [1]. RUS has also been used elsewhere as reviewed by Maynard [2] and by Migliori [3]. Therefore, it is important experim

Discrepancies between previous experimental values of differential cross sections for electron-impact ionization of water vapor and recent model calculations have been largely resolved. A new measurement with improved suppression of spurious electron
