Notes:
Surface roughness is main source of error in instrumented microindentation when it is notnegligible relative to the indentation depth. The effect of a rough surface on the results ofinstrumented microindentation testing using spherical indenter was analyzed by applying the contactdepth model, which takes surface roughness into account. Improved variations in hardness andYoung’s modulus were shown for W and Ni when the results were analyzed by this rough-surfacemodel, while these values were underestimated with increasing surface roughness when analyzed bythe flat-surface model. The deformation state of asperities underneath spherical indenter was alsodiscussed
