Abstract
The effects of β phase decomposition on recrystallization and texture variation in Zr-2.5% Nb alloy pressure tube material were investigated. Isothermal annealing was conducted at 350 to 550 ^oC for 240 hours, and isothermal annealing was performed at 500 ^oC for 240 to 3,000 hours. The recrystallization and texture variation..... More

Abstract
The short range ordering (SRO) reaction of the X-750 Ni-base alloy used as a garter spring material for CANDU reactors was systematically investigated through differential scanning calorimeter (DSC) analysis. Water quenching (WQ) after solution annealing (SA) and 20% cold rolled (CR) X-750 were prepared and these samples were subjected to..... More

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..... More

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
