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.....

Korean J. Met. Mater. 2018;56(2):130-136.   Published online 2018 Feb 5
DOI: https://doi.org/10.3365/KJMM.2018.56.2.130

Abstract
An excellent grain-oriented electrical steel is composed of grains with exact Goss orientation. In order to produce this, it is important to control the Goss-oriented grains during the cold-rolling process. In this study, textures measured by X-ray diffraction (XRD) and electron backscatter diffraction (EBSD) were analyzed for 1, 10, and..... More

Korean J. Met. Mater. 2017;55(5):363-371.   Published online 2017 May 9
DOI: https://doi.org/10.3365/KJMM.2017.55.5.363
Abstract
The effects of the annealing temperature on the microstructure and tensile properties of cold-rolled light-weight steels are investigated using two Fe-30Mn-xAl-0.9C alloys that contain different Al content. The initial alloy microstructure is composed of a single austenite or a mixture of austenite and ferrite depending on the nominal aluminum content.... More
