当氧化皮在氧化过程中膨胀时，会发生起泡。在轧制时，氧化铁皮会引起表面缺陷问题。研究了钢在高温氧化过程中起泡的形核和长大行为。得出以下结论。起泡现象有成核和长大的过程。在成核阶段，氧化皮在氧化皮/金属界面处分层。在此阶段，气泡内的气体成分为CO、CO2和N2。气泡内钢表面发生氧化，其阶段由形核转变为长大。在生长阶段，从氧化皮分离的钢表面不被氧化。
Blistering occurs when oxide scale is swollen during oxidation. Blistered scale causes surface defect problems when it is rolled. Present study investigated the nucleation and growth behavior of blistering when steel is oxidized at high temperature. The following conclusions are drawn. Blistering phenomenon has the nucleation and growth process. At the nucleation stage scale is delaminated at the scale/metal interface. The gas compositions inside blisters at this stage are CO, CO2, and N2. The steel surface inside blisters is oxidized while the stage changes from nucleation to growth. At the growth stage, the separated steel surface from the scale is not oxidized.
