Indentation<br />testing and in particular nanoindentation allows for the local mechanical characterization of<br />materials and their phases. This paper addresses the determination of important mechanical<br />parameters such as hardness, Young’s modulus and indentation energy parameters of single<br />phases in multiphase wear resistant materials. Important influencing factors such as matrix<br />influence on the indentation results of an embedded hard phase, the indentation-size-effect (ISE),<br />the effect of crystallographic orientation, and the fracturing behavior of hard phases are addressed.<br />In addition, the results of scratch tests on the cold work tool steel X210Cr12 and a WC-Co hard<br />metal are presented in order to investigate aspects of the mechanical behavior under abrasion.<br />The deformation behavior under indentation and scratch loading was analyzed by scanning<br />electron microscopy (SEM) and atomic force microscopy (AFM). Besides the experiments<br />supplementary numerical simulations of indentation and scratching testing with the use of the<br />Finite-Element-Method (FEM) are presented. ER -
