一种高强Al-Cu-Mg-Ce变形铝合金及其制备方法
摘要：
本发明公开了一种高强Al‑Cu‑Mg‑Ce变形铝合金及其制备方法，该变形铝合金包含以下重量百分比的组分：Cu 4.3～4.5％；Mg 0.2～0.6％；Ce 0.1～0.3％；Al余量。本发明的Al‑Cu‑Mg‑Ce系变形铝合金，在获得高韧性的同时，也确保了合金具有较高的抗拉强度和屈服强度。由于选择了稀土元素Ce，在实现微合金化的同时可得到最佳的韧化效果，并可以最大限度地减少由于合金化而产生的杂质和夹杂；由于采用Al‑Ce中间合金的形式加入Ce元素，确保了合金成分的精确控制，使得该合金的制备工艺通用性强，操作简单。
摘要（英）：

The invention discloses high-strength Al-Cu-Mg-Ce wrought aluminum alloy and a manufacturing method thereof. The wrought aluminum alloy comprises, by weight, 4.3-4.5% of Cu, 0.2-0.6% of Mg, 0.1-0.3% of Ce and the balance of Al. The Al-Cu-Mg-Ce wrought aluminum alloy has high toughness and further has high tensile strength and yield strength. Because the rare earth element Ce is adopted, while microalloying is achieved, the best toughening effect can be achieved, and impurities and inclusions generated due to alloying can be reduced to the maximum degree. Due to the mode of adding the Ce element into Al-Ce intermediate alloy, accurate control over alloying constituents is guaranteed, and the manufacturing method of the alloy is high in universality and easy to implement.
