چکیده
Four V-Ta-4Cr-4Ti quaternary alloys containing different quantities of Ta were investigated to determine the effect content on Charpy impact properties. Five button-shaped ingots V-4Cr-4Ti ternary alloy and V-xTa-4Cr-4Ti (x = 3, 9, 15, 22 wt.%) fabricated a laboratory scale by using non-consumable arc-melting in an argon atmosphere. tests conducted at temperatures ranging from 77 K 293 instrumented tester. Both upper shelf energy ductile–brittle transition temperature increased with increasing content. The addition 3 wt.% resulted solid solution strengthening without any degradation Thus, (V-3Ta-4Cr-4Ti) is appropriate amount use blanket structural materials for nuclear fusion reactors. spectra TEM-EDS V-3Ta-4Cr-4Ti indicate that there no significant enrichment matrix as compared precipitate. However, thermal aging may result formation Laves phase, causing characterization precipitates, aging, creep need be optimum

Effect 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...

Effect of Cooling Rate on Morphology of TiAl3 Particles in Al–4Ti Master Alloy
The Al-4Ti master alloy was fabricated by aluminum (Al) and sponge titanium particle in a resistance furnace at different cooling rates. This work aims to investigate the relationship between the cooling rate and morphology of TiAl3. The microstructure and composition of master alloys at different cooling rates were characterized and analyzed by optical microscopy (OM), X-ray diffraction (XRD),...
