摘　　要：研究了7050合金厚板生产中采用大道次压下率轧制工艺对板材组织和性能的影响。结果表明:采用大道次压下量轧制工艺,可使板材心部基体中的不溶第二相粒子得到更充分破碎,纤维组织特征更明显,为后续热处理工艺储备足够能量,为提高材料的力学性能及腐蚀性能奠定了基础。The effect of heavy pass reduction rate on microstructure and property of 7050 alloy plate during production was studied. The results show that rolling with heavy pass reduction could more sufficiently break undissolved second phase particle of matrix at plate core part, the fiber texture features are more obvious, which can reserve enough energy for subsequent heat treatment process and lay a foundation for improving mechanical property and anti-corrosion property of materials.
