Abstract

Abstract

Strip cracks along rolling direction on the surface of TA17 alloy cold-rolled sheet were observed by stereoscope,SEM and EDS.Morphology observation indicated that cracks were dominantly in zigzag shape,with 10~30 mm in length and less than 10 μm in depth,and there was no evidence of crack tips.Chemical composition analysis showed that crack regions were characterizd by high oxygen concentration while the intact surface was at normal oxygen level.Test results suggest that the occurrence of strip cracks were mainly related to residual oxide on the surface of TA17 alloy cold-rolled sheet.
