| Abstract: | Vickers-type hardness patterns were investigated by atomic force microscopy. The resulting bitmap images were analyzed to evaluate the elastic relaxation of the impression. A procedure, which is suitable for the comparison of the shape of the residual hardness impression and that of the Vickers pyramid, is presented. With the help of difference images can be verified that the strongest relaxation takes place at the tip and at the horizontal edges of the Vickers pyramid. |
