INFLUENCE OF THE INDENTER GEOMETRY AND THE MODE CONTROL IN HARDNESS MEASUREMENT BY INSTRUMENTED INDENTATION TEST

Abstract:
Taking into account the technical procedures established on ISO/FDIS 14577-1 standard draft, instrumented indentation tests (IIT) were carried out on macro range, in order to determine hardness and other material parameters, so that, using a universal testing machine adapted with a system developed for this end. Two different indenters and two different modes of control were used. It was observed that despite using different modes of control the values of the parameters analysed were similar considering the same indenter geometry. Concerning to the different indenter geometries the bigger hardness values was observed for HV indenter than HBW indenter. Relating to the mechanical work, the results showed in one hand a similar elastic deformation work for both indenters on the other hand it showed a major plastic deformation work for HV indenter than the HBW indenter.
