摘　　要：文章主要研究了TA1箔材表面微观裂纹产生的原因,通过对比两种不同的工艺,可以得出:采用两轧程轧制的箔材表面微裂纹是由于中间退火时氩气保护气氛中氧含量较高,导致箔材表面产生氧化层,进而在第二轧程轧制时氧化层破裂所致。The causes of the surface microcracks of TA1 foil was studied.By comparing two different processes,it can be concluded that:the surface microcracks of the foil rolled by two rolling passes are caused by the high oxygen content in the argon protective atmosphere during the intermediate annealing,which leads to the formation of oxide layer on the surface of the foil,and then the oxide layer cracks during the second rolling pass.
