对T4P态的商用6016铝合金板材沿不同方向的力学性能、显微组织和织构差异进行了研究.结果表明:合金沿不同方向的力学性能均存在明显差异,厚向异性系数r值和加工硬化系数n值均沿轧向最高,而沿45°方向最低;合金已发生完全再结晶,但是各部位再结晶晶粒仍然存在较大差异,表层晶粒数量较多且尺寸细小,而纵截面再结晶晶粒长宽比横截面的要大;合金板材沿厚度方向存在明显的织构梯度,表层主要以Cube织构{001} <100>和不常见的{114} <131>织构为主,而中间层除了Cube织构{001} <100>之外,还存在P{011} <112>、R{124} <211>以及{112} <253>;分析了织构组分与r值的关系,并建立了成形性能、组织和织构之间的定量关系.
