Tensile strength of platinum alloys containing 5-20 mass% Rh were measured in temperature range of 300-873K. Both tensile strength and elongation decreased gradually with increasing temperature. The hardness was also measured using a micro hardness test, which decreased from HV103 at 373K to HV43 at 1273K. At the hardness of HV=50 and at the higher temperature, strongly increased brittleness was observed from the shape of indentation.
