Notizen:
It was impossible to obtain the transverse friction along the strip width in mostprevious studies of cold strip rolling because the surface roughness lays were assumed to be verticalto the rolling direction. In this study, several types of oblique roughness textures were manufacturedon aluminum samples and compression tests were carried out to obtain the effect of differenttextures on the deformation behavior of surface asperity. Different surface textures resulted in verydifferent peak value of stress. It was found that stress was high and changed dramatically at theinitial compression stage but tended to be stable when the total reduction increased. The asperity ofwhich the top angle is 160° showed relatively high resistance to deformation
