摘要:
铸轧纯铝系负极箔坯料存在粗大且分布不均匀的第二相,均匀化退火对坯料中第二相尺寸和分布有重要影响.通过均匀化退火实验研究了退火温度和保温时间对纯铝系负极箔冷轧坯料中第二相尺寸和分布的影响.结果表明:在保温时间为10 h时,随着退火温度升高,弯曲带状FeAl共晶相逐渐溶解球化,条状β (FeAlSi)相分解为短棒状,当温度升高至550 ℃时,针状相FeAl3开始析出;在退火温度为520℃时,随退火时间的延长,粗大第二相的比例不断减小,而后趋于稳定;冷轧变形率为38.5％的铸轧纯铝系负极箔冷轧坯料经520℃保温10 h退火后可获得较均匀的组织.
Abstract:
Coarse and unevenly distributed second phases exist in cast-rolled pure aluminum-based negative electrode foil blanks, and homogenization annealing has an important influence on the size and distribution of second phases in the blank. The effects of annealing temperature and holding time on pure aluminum The effect of the size and distribution of the second phase in the cold-rolled blank of negative electrode foil. The results show that: when the holding time is 10 h, with the increase of annealing temperature, the curved band-shaped FeAl eutectic phase gradually dissolves and spheroidizes, and the strip-like β ( FeAlSi) phase decomposes into short rods, and when the temperature rises to 550 °C, the needle-like phase FeAl3 begins to precipitate; when the annealing temperature is 520 °C, with the extension of annealing time, the proportion of the coarse second phase decreases continuously, and then tends to The cold-rolled cast-rolled pure aluminum-based negative electrode foil blank with a cold-rolled deformation rate of 38.5% can obtain a relatively uniform structure after being annealed at 520°C for 10 h.
