Effect of tantalum addition on the tensile properties of V-Ta-4Cr-4Ti quaternary alloys

چکیده
Various V-Ta-4Cr-4Ti quaternary alloys containing different amounts of Ta were investigated to determine the effect concentration on their tensile properties. Six button-shaped ingots V-xTa-4Cr-4Ti (x = 4, 8, 15, 22, 24, and 35 wt.%) fabricated a laboratory scale by using non-consumable arc-melting in argon atmosphere. The sheet specimens for all examined herein obtained cold-rolling; hot-rolling or intermediate annealing was not required. Although scale, high-Ta alloys, unlike high-Cr did experience crack formation cold rolling process. It is possible that V-4Cr-4Ti adopt large amount its strengthening without negative impact fabricability. Tensile strength tended increase with increasing content at both room temperature high temperatures 973 K 1073 K, which can be attributed solid solution Ta. Thus, addition improve decreasing fabricabilities. However, an alloy excess (V-35Ta-4Cr-4Ti) showed loss ductility brittle fracture mode due friable Laves phase. Therefore, it necessary limit prevent

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...
