Abstract
The effect of solution temperature and quench delay on the microstructure and mechanical properties of an extruded Al-Mg-Si-Cu-Mn alloy was investigated by employing differential scanning calorimetry, transmission electron microscopy, hardness test, and tensile test. The extruded specimens were held at 500 and 540
o
C, respectively, for 80 min for solutionizing.....

https://doi.org/10.3365/KJMM.2019.57.9.555
Abstract
The dynamic precipitation evolution of Mg-3 wt% Zn alloy during extrusion was evaluated in this study. Precipitation evolution during aging has been well investigated for the Mg-Zn alloy, which is known as static precipitation. However, little attention has been given to dynamic precipitation in Mg-Zn alloy. In order to evaluate.....

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.....

Abstract
In this study, the extrusion behavior of Cu fill material in a through-Si-via (TSV) subjected to thermal loading was investigated. The Cu filling of the TSV was accomplished using pulse periodic reverse (PPR) electroplating. To study the extrusion, TSVs of varying via pitch were filled with Cu by electroplating. Defect-free Cu.....

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.....
