In situ crack growth studies of hydrided Zircaloy-4 on a single-edge notched tensile specimen

Forskningsoutput: TidskriftsbidragArtikel i vetenskaplig tidskrift

Abstract

The strains in matrix and hydrides around a fatigue crack tip grown in situ in a single-edge notched specimen of hydrided Zircaloy-4 have been determined using synchrotron X-ray diffraction at various stages of loading. The hydride phase shows proportionally larger strains at full load compared to the matrix strain. The residual strains of the matrix ahead of the crack tip reveal the reverse plastic zone for a crack grown in tension, while the hydride residual strains remain strongly tensile.
