摘要
针对ARCONIC INC和AMAG生产的2024铝合金包铝板材开展了预拉伸变形与组织性能之间关系的研究,结果表明,ARCONIC INC生产的2024铝合金包铝板材较AMAG生产的具有更优的成形性能,AMAG生产的2024铝合金包铝板在预拉伸变形量达到7%~8%时,发生二次再结晶晶粒异常长大,包铝层在预拉伸变形量为4%时即发生粗化,而ARCONIC INC生产的2024铝合金包铝板在预拉伸变形量为7%~8%时发生再结晶粗化,基材在预拉伸变形量达到16%时也未表现出粗化现象。研究结果对于国产铝合金材料生产具有一定的指导意义。
For 2024 aluminum alloy alclad sheets produced by ARCONIC INC and AMAG,the relationship between pre-stretching de-formation and microstructure properties was investigated.The results demonstrate that 2024 aluminum alloy alclad sheets produced by AR-CONIC INC has better forming performance than that produced by AMAG.When the pre-stretching deformation amount of 2024 aluminum alloy alclad sheets produced by AMAG reaches 7%-8%,the secondary recrystallization grains grow abnormally,and the alclad layer coarsens at a pre-stretching deformation of 4%.In contrast,2024 aluminum alloy alclad sheets produced by ARCONIC INC undergoes re-crystallization coarsening when the pre-stretching amount is 7%-8%,and the substrate does not show coarsening when the pre-stretching deformation amount reaches 16%.Thus,the research results have certain guiding significance for the production of domestic aluminum al-loy materials.
