Fracture-Toughness Evaluation of Solution Heat-Treated Zr-2.5Nb Alloys as per ASTM and ISO Standards

CODEN: JTEVAB

Abstract

In the present work, fracture-toughness parameters of Zr-2.5Nb alloy were evaluated as per ASTM E1820 and ISO 12135 standards at 25°C and 300°C. To investigate the influence of the material's microstructure on deviation in fracture-toughness values, Zr-2.5Nb alloy plates were individually water quenched from three soaking temperatures; 850°C, 870°C, and 890°C with 15- and 30-min soaking durations. Under these six conditions, fracture resistance, J-R curves derived from these standards exhibited marginal deviations. However, slope of valid J-R curve region (dJ/da) obtained by two methods had appreciable differences, especially at 300°C.
