Abstract
The elastic properties of polycrystalline HfC0.967, NbC0.964, TaC0.994, and WC1.007 were determined at 23°C, and the data were corrected to theoretical density. In units of 1012 dyn/cm2, the Young's moduli are 4.619, 4.884, 5.377, and 6.237; the shear moduli, 1.953, 1.987, 2.168, and 2.633; and the bulk moduli, 2.426, 3.008, 3.448, and 3.295, respectively. The Poisson's ratios are 0.183, 0.229, 0.240, and 0.185, respectively. The specific electrical resistivities (micro‐ohm centimeters at 20°C, corrected to theoretical density) are 24.6, 49.1, 25.6, and 17.8, respectively.Keywords
