Abstract:
一种Al‑Cu‑Mg‑Ag‑Si‑Sc耐热合金及制备工艺,属于合金材料技术领域。在铝基体加入重量百分比为:2%~4.5%Cu,0.3~0.7%Mg,0~0.6%Ag,0~0.3%Si,0.05%~0.25%Sc。制备方法:在熔炼温度为790±10℃下,将铝锭熔化,加入Al‑Cu、Al‑Ag、Al‑Si、Al‑Sc中间合金和纯镁块,待其熔化后,除气,搅拌,保温静置,浇铸并热处理。处理工艺:合金铸锭在540~570℃固溶处理12~24h后水淬至室温;然后将固溶态合金在150~175℃进行等温时效处理。本发明合金在225~250℃长时间热暴露处理能够保持较高的强度,具有良好的热稳定性。
