This book was released on 1982 with total page 19 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hydride reorientation and delayed hydrogen cracking have been evaluated in specimens cut from the longitudinal and circumferential directions of cold-worked Zr-2.5Nb pressure tubes. In this material basal plane normals were highly concentrated in the circumferential direction. In longitudinal specimens hydrides did not reorient, cracks were not initiated, and artificial cracks grew slowly and only at KI>15MPa.m, whereas in circumferential specimens hydrides reoriented easily, cracks could be initiated, and grew at KI>4.5MPa.m25 25 times faster than cracks at the same KI in longitudinal specimens. Reorientation of hydrides is not necessary for delayed hydrogen cracking, but the degree of reorientation controls cracking susceptibility. Crystallographic texture regulates hydride reorientation and a rotation of basal plane normals from the circumferential to radial direction should reduce the susceptibility of Zr-2.5Nb and other zirconium alloys to delayed hydrogen cracking.

Available in PDF, EPUB and Kindle. Book excerpt: Under conditions of high tensile stress, the Zr-2.5Nb alloy has been shown to he susceptible to a very slow crack propagation failure mechanism. This failure mechanism, hydride cracking, has been studied extensively since leaks developed in the pressure tubes of Reactor Units 3 and 4 at Ontario Hydro's Pickering Nuclear Generating Station in Aug. 1974. The failures have been attributed to reorientation and preferential redistribution of hydrides under high tensile stresses, followed by progressive fracture of these hydrides. Mechanical tests, acoustic emission data, and metallographic studies relevant to this mechanism will be presented and related to the occurrence of cracks in the Zr-2.5Nb reactor pressure tubes.
