Effect of Annealing on Microstructures and Hardening of Helium-Hydrogen-Implanted Sequentially Vanadium Alloys
The effect of post-irradiation annealing on the microstructures and mechanical properties of V-4Cr-4Ti alloys was studied. Helium-hydrogen-irradiated sequentially V-4Cr-4Ti alloys at room temperature (RT) were undergone post-irradiation annealing at 450 °C over periods of up to 30 h. These samples were carried out by high-resolution transmission electron microscopy (HRTEM) observation and nanoi...
متن کاملVanadium Alloys for Fusion Blanket Applications
Vanadium alloys are attractive candidate structural materials for breeding blanket of fusion reactors because of their low activation properties and high temperature strength. Studies on various blanket designs are being carried out using vanadium alloys as structural materials and liquid lithium or molten salt Flibe as breeding and coolant materials. Recently significant progress in fabricatio...
متن کاملEffect of Chromium Content on Mechanical Properties of V-xCr-4Ti-0.15Y Alloys
A combined effect of purification and yttrium (Y) addition was investigated to improve impact properties of high-chromium V-xCr-4Ti alloys. Tensile tests and Charpy impact tests were carried out by using miniaturized specimens. V-10Cr-4Ti-0.15Y alloy had ultimate tensile stress (UTS) at 700 oC and yield stress (YS) approximately equal to and higher than those of V-4Cr-4Ti alloy, respectively. V...
متن کاملOperating temperature windows for fusion reactor structural materials
A critical analysis is presented of the operating temperature windows for nine candidate fusion reactor structural materials: four reduced-activation structural materials (oxide-dispersion-strengthened and ferritic/martensitic steels containing 8–12%Cr, V–4Cr–4Ti, and SiC/SiC composites), copper-base alloys (CuNiBe), tantalum-base alloys (e.g. Ta–8W–2Hf), niobium alloys (Nb–1Zr), and molybdenum...
متن کاملEffects of Heavy-ion Irradiation on Micr at Moderate Temperatures*
V-4 wt.% Cr-4 wt.% Ti alloy is a promising candidate material for first-wall and structural applications in magnetic fusion reactors. In the past, fast neutron sources were used to evaluate postirradiation properties of fusion candidate materials. The recent shutdowns of the Fast Flux Test Facility (FFTF) and the Experimental Breeder Reactor (EBR-II) left U.S. researchers without local experime...
