摘　　要：8011铝箔坯料退火后产生了贯通气泡和微鼓区,气泡内部出现了大量AlFeSi相富集。气泡是由于内部AlFeSi相的富集促进氢富集和氢析出,外部致密的氧化膜阻碍氢析出共同作用形成的。微鼓区的内部AlFeSi相较少,也形成了类似气泡的空腔。因此,AlFeSi相的富集不是气泡形成的必要条件。8011 Al foil blanks generated bubble and micro convex area after annealing, and AlFeSi phase concentration emerged in the interior of bubble. Bubble is due to internal AlFeSi phase concentration which is advantageous to hydrogen enrichment and hydrogen escape, the compact oxidation film outside prevents hydrogen escape. AlFeSi phase concentration in the micro convex area is less, but it also forms a similar bubble cavity. So AlFeSi phase concentration is not the necessary condition to bubble formation.
