2009年12月1日 · In the Al-Zn system, the miscibility gap in the fcc phase closes at 351 °C. The addition of Cu stabilizes this gap, which is stable at 360 °C, even with as low as 0.1 at.% addition of Cu. The gap increases in width with increasing Cu content.

2022年1月20日 · Exposing the commercial Cu/ZnO/Al 2 O 3 catalyst to a H 2 /H 2 O/CH 3 OH/N 2 mixture at 300 °C and atmospheric pressure is found to accelerate the migration of ZnO x species onto the surface of...

2024年8月30日 · Al-Zn-Mg-Cu alloy is a 7XXX series aluminum alloy, which is used by the aviation industry due to their relatively higher specific strength [1], which can be above 570 MPa after T6 heat treatment, while maintaining superior toughness and corrosion resistance [2].

2015年12月1日 · Computational thermodynamics can provide guidelines for the exploitation of Zn–Al–Cu alloys, which are widely used in automotive components [1] and promising Pb-free solders [2]. A reliable thermodynamic description of the Cu–Zn system, especially in Zn-rich corner, is crucial to the reliability of the multi-component Zn alloy ...

2020年4月30日 · The phase diagram of the Al–Cu–Zn ternary system was re-investigated experimentally. The current study was designed to contribute to a better description of those parts of the phase diagram, which are disputed in the current scientific literature.

2017年5月8日 · 摘要： 采用熔铸法制备了Zn含量分别为12wt%、14wt%、16wt%和18wt%的4种高锌Al-Zn-Cu合金，并对合金的显微组织、相组成和力学性能进行了详细分析，重点探讨了合金中Zn的存在形式及其对力学性能的影响。结果表明，4种不同锌含量的合金均由花瓣状的α-Al枝晶和 …

Research studies [17], [18] conducted to overcome the ductility problem of Al-Zn-Cu alloys have shown that both the strength and ductility of these alloys can be improved by thermomechanical treatments. However, there is insufficient information in the literature regarding the effect of thermomechanical processes on the structure and properties ...
