HYDROGEN EMBRITTLEMENT OF TITANIUM ALLOYS
Technical Report
·
OSTI ID:4012484
The effect of various hydrogen interstitial contents between 60 and 312 ppm on the notch sensitivity and low strain rate embrittlement of four titanium alloys was investigated at room temperature. The materials investigated included the alpha-beta alloys Ti-6A1-4V, Ta-2A1-6Mo, and Ti2.5A1-16V, and one all alpha alloy, Ti-5A1-2.5Sn. An optimum embrittling effect was encountered at 180 to 220 ppm hydrogen content in the alpha-beta alloys. Over the range of hydrogen content investigated the alpha alloy was not appreciably embrittled. (auth)
