Small additions of silver can modify age hardening in aluminum alloys that contain magnesium. Thus, although silver has no significant effect on artificial aging on Al-Cu alloys, it causes a complete change to precipitation processes that normally occur in aged Al-Cu-Mg alloys. In this regard, special interest has been shown in those ...

WebThe precipitation sequence of Al–Cu alloys has been investigated extensively [6,7,8,9,10] and the effect of the stretch prior to aging on the precipitation has been of specific concern [11,12,13,14,15]. Small amounts (1~8%) of pre-stretch were observed to enhance the age hardening response in a few of Al–Cu–x alloys [13,14,15]. WebJan 11, 2024 · The Al-Cu-Mg alloy EN AW 2618A (EN AW AlCu2Mg1.5Ni) is used for applications subjected to long-term service at elevated temperatures in the aerospace and transportation industry due to its favorable material properties (e.g., slow long-term degradation) [].It contains Fe and Ni in the form of intermetallic compounds of µm size, … hm joensuu työpaikat https://elyondigital.com
