摘要:
为进一步掌握铝箔坯料在加工过程中组织演变规律，以1235铝合金双零箔坯料为研究对象，探究其7.0 mm厚度铸轧坯料冷轧至3.8，1.8，0.9，0.5 mm过程中第二相的变化情况，结果表明，铸轧坯料冷轧一道次后均匀化退火未改变第二相的属性，只是在一定程度上改变了相的尺寸，组织内的FeAl3相会发生溶解和均匀化扩散，且在高温下部分θ（FeAl3）析出相形貌发生了变化，长大变成针状；后在一道次冷轧至1.8 mm过程中针状相发生了明显的“折断”，但在随后的冷轧过程中，针状相被破碎至5～8 µm范围内以后再很难被进一步破碎，验证了针状第二相“硬而脆”的特性，说明在退火过程中控制尺寸＞5µm的第二相的数量重要性。
Abstract:
In order to master the rule of microstructure evolution of luminum foil stock in the process of cold-rolling, the 1235 aluminum alloy double zero foil billet was studied in this paper, the change of the second phase of the 7.0 mm thickness cast-rolling blank during the cold working was investigated. The results showed that the homogenization annealing for the first pass rolled cast-rolling blank does not change the properties of the second phase, but only changes the phase size to a certain extent, some θ (FeAl3) precipitates dissolve, the morphology of partial θ (FeAl3) precipitates changes and tends to grow up to needle-liked shape; and then the needle-like structures are broken during cold rolling to 1.8 mm, the needle-like phases are difficult to be further broken after being broken in the range of 5 ~ 8 μm, the “hard and brittle” characteristics of the needle-like second phases is verified, and the importance of controlling the quantity of the second phase with the size larger than 5μm during annealing is explained
