Generation of Super Smooth Surface in Compression Test

To investigate the possibility of nanoprocessing by metal forming, the generation of super smooth surface by a simple compression test was attempted. To obtain fundamental information about the generation of a super-smooth surface during metal forming, we investigated a simple compression test of aluminum strips (A1100, 0.8 mm thick). In the present study, to examine the effect of materials, compression tests of copper strips were conducted. The tool and specimen surfaces were observed using a conventional stylus surface profilometer and an atomic force microscope. The tool and specimen surfaces were examined by the power spectrum method and the zeroset method of fractal analysis.
