摘要：

Acoustic emission experiments were conducted during hydrostatic tests and thermal shock tests on flawed pressure vessels. Four 152 mm thick vessels of A-533B and A-508-2 steels with flaws in the vessel walls and in the nozzle corners were tested at various temperatures. Acoustic emissions from cracks were characterized by their temperatures and by the stress field present. Two thermal shock tests, classified as a crack propagation and arrest experiment, were performed. The detected sound pressure levels of acoustic emission resulting from crack propagation during thermal shock were relatively large in comparison with the emissions related to plastic deformation and the approach to crack initiation. © 1979.
