Whittaker, J W; Richey, M W

Electron-beam weldments of U-0.8Ti alloys have demonstrated a sensitivity to hydrogen-assisted-cracking (HAC). A survey experiment was undertaken to determine if RH threshold value exists for HAC formation. Since long periods are often required for crack formation, a method was needed to determine when a crack(s) formed. Acoustic emissions monitoring was selected because of its sensitivity and adaptability to long-term monitoring. 1 ref., 5 figs., 3 tabs.
