Description

Cold worked Zr-2.5Nb alloy with 500 ppm and 300 ppm of hydrogen charged was tested for behavior of hydride by OM,SEM,TEM. Hydrides regardless of quantity of hydrogen contents caused nucleation growth of δ-hydride at boundary of α-Zr/β-Zr. Hydride at CANDU pressure tube grew along resident area. In cross-section vertical to longitudinal direction hydrides grew with azimuthal relationship of (1111)δ//(0001)α, [0001]δ//[1120]α and in cross-section vertical to circumferential direction micro hydride plate grew accumulating in the longitudinal direction.
