The Tensile Properties of Iridium at High Temperatures

Abstract

In this paper the authors describe their determination of the tensile strength and ductility of iridium at temperatures up to 2000° C. The tensile strength of iridium at high temperatures, in the presence of carbon vapour, compares favourably with those of tungsten, molybdenum, tantalum and niobium, all of which are attacked to a much greater degree by the carbon.
