description | In accordance with an embodiment of the present invention, an aluminum alloy material, which is an aluminum alloy including a grain boundary and a plurality of grains divided by the grain boundary and having a face-centered cubic crystal structure, includes a band formed by employing at least one nonmetallic element selected from among oxygen (O), carbon (C) and nitrogen (N) on an aluminum matrix. Each of the grains includes a plurality of sub-grains divided by a low-angle grain boundary (LAGB), and the band located in the low-angle grain boundary can form a coherent interface with the aluminum matrix. A plurality of potentials already existing in the band can reduce a potential cell in size in case of plastic deformation, thereby largely contributing to an elongation improvement. Such an aluminum alloy material can be cold-rolled at a high draft percentage, which can result in the acquisition of a board with significantly improved elongation.
본 발명의 실시예에 따른 알루미늄 합금 재료는, 그레인 바운더리(grain boundary) 및 상기 그레인 바운더리에 의해 분할되는 복수의 그레인(grain)을 포함하며 면심입방 결정구조를 갖는 알루미늄 합금으로, 산소(O), 탄소(C) 및 질소(N) 중 선택된 하나 또는 이상의 비금속 원소가 알루미늄 기지에 고용되어 형성된 밴드(band)를 포함한다. 상기 그레인들 각각은 소각 그레인 바운더리(Low-angle grain boundary, LAGB)에 의해 분할된 복수의 서브-그레인들을 포함하고, 상기 소각 그레인 바운더리에 위치하는 밴드는 알루미늄 기지와 정합 계면(coherent interface)을 형성할 수 있다. 상기 밴드에는 다수의 전위가 이미 존재하여 소성변형 시 전위 셀의 크기를 줄여 연신율 향상에 크게 기여한다. 이러한 알루미늄 합금 재료는 높은 압하율의 냉간압연이 진행될 수 있고, 그 결과 연신율이 현저하게 향상된 판재를 얻을 수 있다. |
