Description
技术领域
本发明属于铝合金的加工技术领域,特别涉及一种同时提高3003铝合金板材强度和塑性的深冷加工方法。
背景技术
3003铝合金是一种不可热处理强化,但可通过形变加工强化的形变铝合金。3003铝合金具有良好的耐腐蚀性能、导电性、导热性和焊接性能,被广泛应用于压力容器与管道、工程机械交换器、飞机油箱和油路导管等。3003铝合金抗拉强度较低,仅稍高于工业纯铝,这极大限制了3003铝合金在其他领域的应用。
作为结构材料用的3003铝合金必须具有高的强度和良好的塑性,3003铝合金目前的强化技术手段主要是形变强化,如等通道角挤压、高压扭转、普通室温轧制和累积叠轧等技术。这些形变强化技术中,等通道角挤压和高压扭转方法仅适用于小试样,且成本极高,无法实现大块板材的成形加工。累积叠轧工艺复杂,结合面结合强度较低。通过累积叠轧工艺加工的板材,强度可明显提高,但是当抗拉强度高于160MPa时,其延伸率却低于5%。对于普通轧制工艺加工的铝合金板材,其抗拉强度随应变量的增加而增加,但其延伸率却随着变形量的增加而显著降低。因此,这些形变强化方法都限制了3003铝合金的应用领域。因此,如何通过简单的形变加工工艺同时提高3003铝合金强度和塑性是铝合金应用领域技术人员亟需解决的技术问题。
发明内容
针对上述现有技术存在的问题及不足,本发明的目的在于提供一种工艺简单、能够同时提高3003铝合金抗拉强度和塑性的深冷加工方法。本发明通过热处理和液氮深冷轧制相结合的方法,获得的3003铝合金板材的强度和塑性得到大幅度提高,显著高于室温轧制的3003铝合金板材。
本发明的技术方案如下:
提高3003铝合金板材强度和塑性的深冷加工方法,包括以下步骤:
(1)将3003铝合金板材放入马弗炉中从室温随炉加热至590℃,保温6小时,随后水冷至室温;
(2)将步骤(1)热处理后的3003铝合金板材放在液氮中浸泡10min,采用二辊轧机对浸泡好的3003铝合金板材进行深冷轧制,采用多道次轧制方式进行轧制,每道次压下量为原始厚度的9~11%,一般为10%左右,每道次轧制结束后,迅速放入液氮中浸泡10min,再进行下一道次的轧制;
(3)将步骤(2)轧制后的3003铝合金板材进行室温拉伸。
所述的3003铝合金板材的化学成分的wt%为:Si 0.61、Fe 0.4、Cu 0.13、Mn1.26、Zn 0.10,Al余量。
步骤(2)中,板材轧制后最终的变形量分别为原始厚度的30%、50%和70%。
步骤(3)中拉伸,30%轧制变形量的合金板材的强度和延伸率分别为168.81MPa和15.52%;当轧制变形量为50%时,3003铝合金板材的强度和和延伸率分别为186.47MPa和12.67%;当轧制变形量为70%时,3003铝合金板材的强度高达203.60MPa,延伸率依然保持在9.55%。
本发明与现有技术相比具有如下优点:
1、工艺简单、操作方便。
2、可以细化3003铝合金板材的晶粒,大幅度增加合金内部的位错密度,提高3003铝合金的力学性能。与普通室温轧制工艺相比,在相同变形量条件下本发明采用的加工技术可同时提高3003铝合金板材的抗拉强度和延伸率。
