Abstract：

The　competition　between　precipitation　and　segregation　of　Sc　and　its　effects　on　thermal　stability　of　Al-CuMg-Ag　alloys　were　investigated　in　this　paper.　Al-Cu-Mg-Ag-Sc　has　good　thermal　stability　due　to　the　precipitation　of　Al3Sc　phases,　but　no　segregation　of　Sc　atoms　on　the　interface　of　the　Omega　phases　and　the　transformed　0＇　phases.　Al-Cu-Mg-Ag-Si-Sc　alloy　has　the　best　thermal　stability　due　to　Sc　atoms　segregate　to　the　0＇　phase　thus　inhibit　the　growth　of　the　0＇　phase.　(C)　2021　Elsevier　B.V.　All　rights　reserved.
