摘　　要：为合理制定5083铝合金板材的生产工艺,对冷变形及稳定化退火后的5083铝合金板材的组织与晶间腐蚀性能进行了试验研究。结果表明,船用5083铝合金板材的晶间腐蚀性能与β相的分布、析出量密切相关。采用25%~35%冷加工变形并稳定化退火后,板材的力学性能满足相关标准要求,腐蚀性能优良,β相在晶粒内均匀分布,无连续的沉淀析出网状结构。Microstructure and intergranular corrosion property of 5083 aluminum alloy sheet were studied after cold deformation and stabilizing annealing to obtain reasonable production process. The results show that its intergranular corrosion property is bound up with the quantity and distribution of β phases. After 25%- 35% cold deformation and stabilizing annealing,its mechanical properties meet standard requirements,corrosion properties are good,reticular structure discontinuously precipitates out,and fine β phases are distributed uniformly within the grains.
