While uranium alloys have been observed to stress corrosion crack in a variety of environments, a previous study has shown that the principal stress corrodent for U-0.75 Wt percent Ti in air and aqueous environments is H$sub 2$O. Since uranium alloys, particularly alloys with low alloy additions, react rapidly with H$sub 2$O to form uranium oxide and H$sub 2$, a program was initiated to determine the cracking behavior of U-0.75 Wt percent Ti in H$sub 2$. Preliminary data obtained from material aged at 357$sup 0$C for 18 hours (sigma/sub ys/ approximately equal to 900 Mn/m$sup 2$, 130 ksi) and tested in 100 torr of H$sub 2$ are given. (auth)
