High temperature resistivity determination of high-melting point metals and alloys

A method of determination of temperature-dependent electrical resistivity for metals and alloys of high-melting points at high temperatures is presented. It is based on the computer simulation of wire heating by direct current and basic electrical measurements. The authors present new results for 25Re75W and 47.5Re52.5Mo alloys along with the results of test measurements for tungsten. Electrical resistivity for tungsten obtained with presented method is in good agreement with well known data for the metal.
