Korean J. Met. Mater. 2022;60(12):892-901.   Published online 2022 Nov 25
DOI: https://doi.org/10.3365/KJMM.2022.60.12.892

Abstract
General austenitic stainless steel has a problem with intergranular corrosion due to volatilizing chromium, which forms chromium carbide in a high temperature environment. By adding titanium as an alloying element, STS 321 stainless steel has excellent creep resistance and intergranular corrosion resistance at high temperatures, because the formation of chromium.....

Korean J. Met. Mater. 2020;58(10):703-714.   Published online 2020 Oct 5
DOI: https://doi.org/10.3365/KJMM.2020.58.10.703

Abstract
Al-Mg-Si alloy was rolled asymmetrically at several temperatures to apply shear deformation, and the effects of the initial precipitate on shear deformation, texture evolution, formability, and plastic anisotropy were studied. Texture was analyzed using a EBSD, and the formability and plastic anisotropy of the specimen were evaluated using the value..... More

Korean J. Met. Mater. 2018;56(10):734-744.   Published online 2018 Oct 5
DOI: https://doi.org/10.3365/KJMM.2018.56.10.734

Abstract
The microstructure, texture evolution, and room temperature formability of warm-rolled and coldrolled AZ31 magnesium sheets were investigated in this study. The localized deformation regions, i.e., shear bands, formed during warm-rolling and cold-rolling mainly provide nucleation sites for recrystallization, but the orientation of the recrystallized grains nucleated on the shear bands.....
