STRESS-STRAIN MEASUREMENT IN HEAVY LIQUID METALS

open access: yesMM Science Journal, 2022
The mechanical testing in heavy liquid metals is performed in order to obtain information about the influence of the liquid metal on Generation IV candidate construction materials. For testing in heavy liquid metal environment, it is required to test comparably with standards of mechanical testing in air at high temperatures.
