Mechanical Properties of Refractory Metals at Extremely High Temperatures

Abstract:

Driven by the unavailibility of commercial test equipment for tensile and creep testing at temperatures up to 3000°C a measuring system has been developed and constructed at the University of Applied Sciences, Jena. These temperatures are reached with precision by heating samples directly by electric current. Contact-less strain measurements are carried out with image processing software utilizing a CCD camera system. This paper covers results of creep tests which have been conducted on TZM sheet material (thickness 2 mm) in the temperature range between 1200°C and 1600°C. It is the aim of this work to show the influence of heat-treatment conditions on creep performance in the investigated temperature range.
