Comparative Study on the Texture Evolution and Formability of Warm-Rolled and Cold-Rolled AZ31 Magnesium Alloy Sheets
온간 압연 및 냉간 압연으로 제조한 AZ31 마그네슘 합금 판재의 집합조직 및 성형성 비교

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(10):699-707.   Published online 2018 Oct 5
DOI: https://doi.org/10.3365/KJMM.2018.56.10.699

Abstract
The microstructure, tensile properties at room and elevated temperatures, and high-cycle fatigue behavior of an extruded Mg-7Sn-1Al-1Zn (TAZ711) alloy were investigated in comparison with those of an Mg-8Al-0.5Zn (AZ80) alloy extruded under the same conditions. The extruded AZ80 alloy exhibited a fully recrystallized structure, whereas the extruded TAZ711 alloy had..... More

                        
Effect of Al Addition on the Microstructure, Tensile Properties, and Bendability of Extruded Mg-7Sn-1Zn Alloy
Al 첨가가 Mg-7Sn-1Zn 합금 압출재의 미세조직과 인장 및 굽힘 특성에 미치는 영향

Korean J. Met. Mater. 2018;56(1):40-48.   Published online 2018 Jan 1
DOI: https://doi.org/10.3365/KJMM.2018.56.1.40

Abstract
The effect of Al addition on the microstructure and mechanical properties of extruded Mg-Sn based alloy is investigated by adding 1 wt% Al to the Mg-7Sn-1Zn alloy and indirectly extruding the billets with and without the Al addition. The Al addition promotes dynamic recrystallization (DRX) behaviour during hot extrusion, which..... More

Korean J. Met. Mater. 2017;55(5):296-307.   Published online 2017 May 9
DOI: https://doi.org/10.3365/KJMM.2017.55.5.296
Abstract
Magnesium alloys, which possess excellent specific strength and castability, are highly susceptible to corrosion. Although anodizing is widely used to resolve this problem, it requires toxic electrolytes and produces relatively thin and weak surface coatings. Recently, plasma electrolytic oxidation (PEO) has emerged as an alternative to anodizing. Although it is... More
