PHYSICAL AND THERMAL-PROPERTIES OF V-4TI-4CR AND V-8TI-5CR ALLOYS

Ambient-temperature density, Young's and shear moduli. Poisson's and e xpansion ratios. 20-940 C thermal conductivity of V-4Ti-4Cr and V-8Ti- 5Cr alloys. promising structural materials for first walls of thermonu clear reactors. have been measured. Analytical temperature dependences of measured properties have been obtained. A comparison of physical a nd thermal properties of investigated alloys among them and with liter ary data for vanadium has been carried out. Annealed V-4Ti-4Cr alloy f eatures the best combined properties as first-wall thermonuclear-react or material.
