Abstract

This paper reports the results of uniaxial and compression tests on IC-218LZr extruded bars at temperatures from 700 to 1000°C in air. Tensile results indicate reduction in ductility at temperatures between 750 to 900°C. However, the results show improvement in ductility above 950°C. Compression test results do not show a decrease in the ductility in the temperature range.
