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.....

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
o
C or higher, elongation significantly increased and dissolution of the η′ phase occurred. η′ is the main hardening phase. After.....

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.....
