概要

• 論文の詳細を見る

• Mechanical properties were studied by tensile test of a Ti-15V-3Cr-3Sn-3Al alloy obtained by duplex-aging after cold-swaging, i.e. aging at high temperatures followed by re-aging at a lower temperature. Combinations of short-time aging at 823, 873 and 923 K and re-aging at 673 K have greatly improved the strength-ductility balance of this alloy, realizing high strength of about 1.8 GPa with tensile elongation of 5%. This duplex-aging process further diminishes the influence of the amount of reduction by cold-swaging on the mechanical properties after aging.
