DOI: https://doi.org/10.3365/KJMM.2022.60.4.329

Abstract
The effect of Cu content on the microstructure and mechanical properties of Al-8.0Zn-2.5Mg-xCu (x: 0, 1, 2, 3) aluminum alloys manufactured by the twin-roll casting process was investigated. The Al-8.0Zn-2.5Mg-xCu alloy showed an increase in surface defects with increasing Cu content. This is because the amount of residual liquid in..... More

Korean J. Met. Mater. 2022;60(1):83-93.   Published online 2021 Dec 14
DOI: https://doi.org/10.3365/KJMM.2022.60.1.83

Abstract
The effects of dissolution of the η′ phase by solution treatment on the mechanical properties of A7075-T6 alloy were investigated. Immediately after solution treatment of the T6 sheet at 450 oC or higher, elongation significantly increased and dissolution of the η′ phase occurred. η′ is the main hardening phase. After..... More

Korean J. Met. Mater. 2019;57(6):396-404.   Published online 2019 May 16
DOI: https://doi.org/10.3365/KJMM.2019.57.6.396

Abstract
The effects of natural and pre-aging on the microstructure and mechanical properties of Al-8.0Zn-2.5Mg-2.0Cu aluminum alloy sheet fabricated by twin roll casting were investigated. Immediately after solution treatment, the Al-8.0Zn-2.5Mg-2.0Cu alloy sheet had a yield strength of 173 MPa and elongation of 19.5%. The hardness of the Al-8.0Zn-2.5Mg-2.0Cu alloy sheet..... More
