Description
一种高强度铸造铝合金材料 技术领域
本发明涉及一种铝合金材料， 具体来说是一种高强度铸造铝合金材料。 背景技术
铝合金是一种较年轻的金属材料，在 20世纪初才开始工业应用。第二次世界 大战期间， 铝材主要用于制造军用飞机。 战后， 由于军事工业对铝材的需求量骤 减， 铝工业界便着手开发民用铝合金， 使其应用范围由航空工业扩展到建筑业、 容器包装业、 交通运输业、 电力和电子工业、机械制造业和石油化工等国民经济 各部门， 应用到人们的日常生活当中。 现在， 铝材的用量之多， 范围之广， 仅次 于钢铁，成为第二大金属材料。铝合金的发展可追溯到 1906年时效强化现象在柏 林被 Alfred Wilm偶然发现， 硬铝 Duralumin、 随之研制成功并用于飞机结构件上。 在此基础上随后开发出多种 Al-Cu系合金。 法国于 20世纪初研制成功 A-U5GT ((W)si<0.05 , (W)Fe≤0.10%)铝合金，抗拉强度（T4)≥275Mpa、 SAEJ452-1989), 投入生产应用， 已列入法国国家标准和宇航标准； 美国铝协会牌号 201.0(1968年) 和 206.0(1967年)合金都是在 A-U5GT基础上经改进而形成的， 1974年的 204.0铝合 金等同于 A-U5GT; 201.0(AlCu4AgMgMn)的商业名称是 KO-l(ASTMB26/B26(M) - 1999, 抗拉强度 T7状态为 415Mpa， 延伸率 3%)， 受美国专利保护， 且成分含 Ag(0.4 -1.0 ), 成本高。 俄罗斯 BAJI10主元素成分相当于国内的 ZL204, 但添 加微量元素保密， 仅用于军事或其他要求高的领域。
我国研制了 ZL204A、 ZL205A等铸造用铝合金牌号， ZL204A T5状态值下抗 拉强度 440Mpa， δ5〉4%， 但该合金在 Al-Cu系铸造合金中流动性最差， 抗热裂性 最差。 按技术标准 (GB1173-86)规定， ZL205A的抗拉强度 T5状态为 435Mpa， T6 状态下为 465Mpa(GB/Tl 173-1995标准， ZL205A(T6)的抗拉强度为 470 Mpa), 是 目前世界上强度最高的铸造铝合金材料之一。 ZL205A (T5 ) 的塑性好， 伸长率 可达 7%， 该合金已在我国航空、航天领域得到广泛应用， 但其成分含有 V贵重金 属元素， 价格高昂； 同时， 需用精铝或高纯铝作基体金属， 不但增加成本， 原料 供应也受限制。 另外， 在 ZL205A基础上加入 RE研制了 ZL209, 仍受添加 V元素
成本高的限制。 北京航空材料研究院吕杰等研制出一种与 ZL205 A主成分相近的 铝合金， 但微量元素中含有 0.1%-0.25%V，其抗拉强度在 385-405Mpa之间、 伸长 率达 19 %〜23 %， 仅见文献研究报道， 且抗拉强度稍低， 原材料含有价格昂贵的 V。
综上所述， 可知目前国内外在高强度铸造铝合金领域研究中存在的问题有： 强度不够高， 极少有高于 450Mpa的铸造铝合金； 配方中普遍加入了千分之一以 上的贵金属和稀有元素 (银、 钒、 铍等)， 且基体金属多采用高纯级铝， 成本高， 原料来源受限， 难以在民用领域推广应用； 未能解决强塑比问题， 合金强度与可 铸性的矛盾突出； 疲劳寿命短， 抗应力腐蚀性差。 发明内容
本发明所要解决的技术问题是针对目前高强度铸造铝合金领域存在的高成 本配方， 强度低， 可铸性差， 疲劳寿命短， 抗应力腐蚀性差等技术难题， 通过优 选普通元素配方和熔铸、净化等工艺，研制出高强高韧高抗蚀性的军民两用铸造 铝合金材料。
为了解决上述问题，本发明提供了一种高强度铸造铝合金材料，按重量百分 比计， 该合金成分为 Cu 2.0〜6.0%， Mn 0.05〜1.0%， Ti 0.01〜0.5%， Cr 0.01— 0.2%, Cd0.01 ~0.4%, Zr 0.01—0.25%, B0.005~0.04%, 稀土元素 0.05〜0.3ο/ο， 其余为 Α1及微量杂质元素。
稀土元素为 Pr、 Ce、 La或混合稀土 RE。
混合稀土 RE中所含的各种稀土的总量不小于 98重量％ (以混合稀土 RE的总 重量为基准） 。
混合稀土 RE含 40〜50重量％的铈 （以混合稀土 RE的总重量为基准） 。
该高强度铸造铝合金材料的制备方法包括如下步骤：
(1)往熔炼炉中加入适量的铝锭或熔融铝液， 加热使之完全融化并在 660〜
850 °C下保温；
(2)再按配方比例先加入 Cu、 Mn合金元素搅拌均匀后再加入 Ti、 Cr 、 Cd、 Zr、 B、 稀土元素 Pr、 Ce、 La或混合稀土 RE微量元素， 搅拌均匀；
(3)然后对上述合金熔体进行炉内精炼； 往合金熔体中加入精炼剂 (可根据不
同工况采用氯气、 六氯乙烷、 氯化锰等作为精炼剂)， 并搅拌均匀， 同时为防止 熔体吸入水份和烧损， 熔体精炼应尽可能在封闭环境中操作；
(4)合金液倾倒出炉， 在线过滤、 除气、 除渣处理；
(5)金属型铸造；
(6)最后在进行 620°C以下、 72小时以内的固溶析出强韧化热处理。
与现有技术相比， 本发明具有如下优点：
(1)先进的合金成分设计及微合金化设计。 在 Al-Cu-Mn主成分的基础， 找到 了合理的微合金元素 （Ti、 Cr 、 B、 Zr、 稀土元素 Pr、 Ce、 La和混合稀土等） 并 确定其成分范围， 能够实现替代贵重稀有金属 Ag、 V等的作用， 降低了配方成本 5〜10%。
(2)先进的熔炼除杂技术，有效破解了除杂的技术瓶颈， 使材料的抗拉强度大 于 450Mpa， 同时延伸率大于 5%。
(3)在保持高强度的同时能明显提高其塑性的方法。
本高强度铸造铝合金材料 1经科技部西南信息中心查新中心查新结论为："采 用本项目所述元素成分达到所述参数的'新型高强度铸造铸造铝合金研发及产业 化'， 国内外未见文献报道。 "该课题知识产权和研究成果不会产生纠纷和冲突。
