... (fracturing) Forgings Laps Pressure vessels Seams Alloy steel Metalworking-related failures Certain forged pressure vessels are subjected to autofrettage during their manufacture to induce residual compressive stresses at locations where fatigue cracks may initiate. The results of the autofrettage...

... for testing. Analysis (visual inspection, 100x nital-etched micrograph, fluorescent magnetic-particle testing, and metallographic examination) supported the conclusion that the rod failed in fatigue with the origin along the lap and located approximately 4.7 mm below the forged surface. The presence of oxides...

.... The investigation results suggest that the root cause of failure was a forging lap that occurred during manufacturing. Precracks induced by the forging defect and the influence of preload stress (due to bolt torque) caused the premature failure. cable clamps brittle fracture forging overlap copper alloy...
