AN INVESTIGATION OF THE EFFECTS OF IMPURITIES AND METALLURGICAL VARIABLES ON THE NOTCH SENSITIVITY OF TITANIUM ALLOYS. Period Covered: March 1, 1957 to February 28, 1958

Technical Report ·
OSTI ID:4260770
The notch tensile propenties of three commercial titanium-base alloys, A110AT (Ti -5.0Al--2.5Sn), Ti6Al-4V, and Ti-140A (Ti-2Fe-2Cr-2Mo), were investigated at six interstitial levels, four microstructural conditions, and over a range of temperatures from - 196 to 200 C. Notch sensitivity generally was increased by increased interstitial content, low temperature, and acicular- type microstructures. In addition, sensitivity to slow-strain hydrogen embrittlement was observed in the temperature range near 0 C at hydrogen levels well below specification limits. (auth)
