    Abstract

    In this paper a method of characterization of plastic material properties of the surface layers constituted by laser alloying is proposed. The applied characterization method is based on the analysis of load-penetration depth curves obtained in repeated loading-unloading-reloading microindentation tests. Spherical indenters were used. A Stellite™ alloyed layer and a tungsten carbide alloyed layer were considered. The results of metallographic analysis of the layers and their microstructure are presented. The method was also used for the characterization of plastic parameters for carbon steel. Its stress-strain curve generated by the characterization process is compared with that obtained in a tension test.
