Notched and unnotched tensile specimens of Mo--0.5 Ti, F--48 (Cb-- 15 W-- 5 Mo-- 1 Zr), and Ta--10 W were tested over a range of temperatures selected to encompass their ductile-to-brittle transitions. Recrystallized structures of Mo-- 0.5 Ti exhibited greater tendencies toward brittle behavior than did stress- relieved structures. The addition of 0.5 Ti to molybdenum lowers the transition temperature slightly. Recrystallized F-- 48 exhibited evidence of notch sensitivity and brittle behavior above room temperature. Stress-relieved F--48 became brittle and notch sensitive slightly below room temperature. No serious problems of brittle behavior or notch sensitivity were detected with Ta- 10 W at temperatures as low as --420 deg F. (auth)
