Abstract
The precipitation characteristics of hydrides in Zr-2.5% Nb pressure tube material were investigated for various hydrogen concentrations and homogenization temperatures. A surface hydride was formed using the electrolytic method and homogenized at various temperatures up to at 550 oC. The homogenization treatment was carried out at 300-550 oC over 240.....

Korean J. Met. Mater. 2016;54(12):875-884.   Published online 2016 Dec 5
DOI: https://doi.org/10.3365/KJMM.2016.54.12.875

Abstract
The deformation mechanism at room temperature in water quenched (WQ) and furnace cooled (FC) mild steels was investigated in a plane tilted 45° from the tensile direction, using electron back scattered diffraction, XRD, and TEM. The occurrence of (211) twinning was confirmed by pole figures and the slip systems were..... More
