    • By making use of low-carbon steel K08Al, 08Al, the change of surface roughness Rz,Rm value according to the forming paths of uniaxial, plane, biaxial, uniaxial-biaxial and biaxial-uniaxial deformation models was investigated. The initial value fo and the change of inhomogeneity of thickness fR with strain were measured. The results show that the surface roughness Rz, Rm increase linearly with the increase of strain while inhomogeneity of thickness fR decrease in each forming path.
