ACOUSTIC EMISSION AND STRESS-CORROSION CRACKING OF U-4 1/2 WT% NB

STRESS-CORROSION CRACK PROPAGATION IN U-4 1/2 WT%NB HAS BEEN MONITORED WITH CRACK-OPENING DISPLACEMENT AND ACOUSTIC- EMISSION TECHNIQUES. EXCELLENT CORRELATION WAS OBTAINED BETWEEN THE DIRECT CRACK-VELOCITY MEASUREMENTS AND THE EMISSION COUNT RATE AT ALL STRESS INTENSITIES. THE DATA ALSO SHOW THAT, AS THE CRACKING VELOCITY INCREASES, THE COUNTS PER UNIT AREA OF NEW CRACK SURFACE INCREASE. THE RESULTS OF THE INVESTIGATION SHOW THE FEASIBILITY OF ACOUSTIC-EMISSION DETECTION TECHNIQUES AS A USEFUL STRESS-CORROSION TESTING TOOL.
