| Abstract: | Water bathed thermal shock damage experiments with standard compress specimens of PBX JOB 9003 without thermally processing were performed. The ultrasonic characteristics were tested both before and after the thermal shock damage experiments. The experiments show that there is an apparent critical temperature gap for JOB 9003 specimens damaging and cracking, and some relevant ultrasonic characteristics have been obtained. |
