HIGH STRENGTH ALLOYS OF THE Ti-Al-Mo-V SYSTEM,

Abstract

A study was made of several Ti-Al alloys alloyed with one or two beta-stabilizing elements (Mo and V). The alloys were cast into 6 kg ingots which were forged into bars 25 mm in diameter and finally rolled into sheets 1.5 mm thick. To increase the plasticity of the sheets, they were annealed at 750 degrees C and furnace cooled. Specimens cut from the sheets, water-quenched from 780 degrees C and aged at 480-520 degrees C for 8 hr were tensile tested. The optimal combination of mechanical properties was found in Ti-4Mo-8V-2Al-0.05Zr alloy (tensile strength 145 kg/mm (to the second power), elongation 9.5 percent and reduction of area 40 percent) and in Ti-5Mo-6V-2Al-0.05Zr alloy (tensile strength 147 kg/(sq mm), elongation 7 percent and reduction of area 30 percent).
