【摘要】：以1235铸轧板(7.0 mm)经过两道次冷轧后的1.1 mm厚的冷轧坯料为对象,借助光学显微镜(OM)、扫描电子显微镜(SEM)及能谱分析仪(EDS)、定量金相分析技术和电解抛光等试验手段,研究了退火温度对1.1 mm厚的1235铝箔坯料组织的影响。结果表明:在相同的退火时间(6 h)内,随退火温度(320~420℃)升高,析出相(Al Fe Si)数量先增加而后减少且粗化;退火温度为380℃时,析出相数量多且均匀细小,平均尺寸约为3μm。再结晶温度的区间为320~340℃;随着退火温度升高,再结晶晶粒逐渐长大;退火温度为380℃时,再结晶晶粒数量多且均匀细小,平均尺寸约为23μm。因此,在380℃保温6 h的退火工艺最佳。
