MATERIALS CHARACTERIZATION STUDY Ultrasonic Longitudinal and Shear Velocities of Candidate Isotope Encapsulation Materials

摘要

Ultrasonic longitudinal and shear velocities were measured for Inconcel X, Hastelloy X, Hastelloy C, TZM, 304L, 416, L605, Haynes 25, tungsten, tantalum, and molybdenum, which are candidate cladding materials for isotope heat capsules. The specimens used for this program were random samples of several configurations which required the use of different methods for velocity measurements. The differential path method was employed when possible because of its inherent accuracy. The pulse echo method and the through transmission method were required for some specimens, while for others the plate resonance method was used.
