| Abstract: | Several methods of microhardness and nanoindentation test on the surface layer of material are discussed in this paper. The characteristics and the testing range of several microhardness instruments are introduced. The emphasis of this paper is the differences in essence between microhardness and nanoindentation hardness. At last, using the FEA simulation and nanoindentation test, the quantitative relationship between Vicker microhardness and nanoindentation hardness is given. |
