The specific electrical resistivities of seven transition metal carbides (zirconium carbide, hafnium carbide, niobium carbide, tantalum carbide, dimolybdenum carbide, ditungsten carbide, and tungsten carbide) and ten transition metals (scandium, yttrium, titanium, zirconium, hafnium, niobium, tantalum, chromium, molybdenum, and tungsten) were measured between 2 ° and 300 °K. The data were fitted from 2 °K, or higher for the superconducting materials, to the crossover temperature T 0 by the expression g( T) = ϱ 0+ βT n , and from T 0 to 300 °K by the Bloch-Grüneisen function plus a constant. The latter expression represented the high-temperature data well, whereas the low-temperature expression represented most of the data fairly well. The parameters derived from these two expressions are discussed and compared.
