WebDec 21, 2024 · After an only 3-hour short pre-aging treatment at 100 °C, the two investigated alloys, based on commercial EN AW-5182 and modified with additions of Zn and Zn + Cu respectively, show high formability due to increased work-hardening. Then, these alloys exhibit a giant hardening response of up to 184 MPa to reach a yield … WebThe property of Al-Mg-Zn (-Cu) alloys also can be efficiently improved by adding additional elements. By adding Ni and Cu to Al–5Mg–3.5Zn (at%) alloy, the creep-rupture life of alloys was distinctly extended to 665 h at 200 ℃/105 MPa, which was 10 times than that in Al–5Mg–3.5Zn (at%) alloy [9]. WebAn alloy with added Zn, Cu and Ag showed improved strain hardening and reduced serrated flow in the soft state, while exhibiting an age-hardening response of up to 326 … manor care naperville il
