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.....

2018;56(6):472-478. Published online 2018 Jun 4
DOI:
https://doi.org/10.3365/KJMM.2018.56.6.472
Abstract
We developed a multi-scale modeling framework using the thermodynamic UW1 database of the Fe-Mn-Ni-Si quaternary system. To obtain input data for the phase-field model, such as mobility and interfacial energy data, we used DICTRA software and the TC-PRISMA package with the commercial TCFE8 and MOBFE3 databases. Using the developed framework,.....
