Abstract:

Composiions ased upon V-1wt- Ti-60 wt- Cb and V-1 wt- Hf-60 wt- Cb complexed wth 0.05 to 0.1 wt- O andor N were evaluated for fabricability. the materials containing less than 0.06 wt- deliberate interstitial additions could be rendered to sheet by warm F working compositions with greater amounts could not be fabricated even by hot working in the temperature range 1800 to 2400 F. Tensile evaluations conducted on V-5 wt- Ti-20 wt- Cb and V-5 wt- Ti-20 wt- Cb-0.05 wt- O at 2000 F in He showed that the addition of 0.05 wt- O resulted in approximately a 40 increase in strength. A large number of V-base alloys were also evaluated for tenile strength at 2400 F. The highest 2400 F ultimate tensle strength measured was 12,700 psi for the alloy V-1 wt- Ti-60 wt- b, a value comparable to that measured for several commercial and experimental Cb-base alloys. In addition, several compositions were equally as strong on a densitycorrected basis. Author
