The characteristics of sheared surfaces of ductile metals are fundamentally interesting for tribological performance. This research applies an atomic force microscope (AFM) to characterize the shear patterns and characteristics of pure copper metal. Two approaches were used, micro indentation and equal channel angular extrusion (ECAS). This poster discusses our findings in nano scale behavior of shear and compares the process of materials deformation. New insight of ductility for wear is reported.
