Analysis of the Indentation Size Effect in the Microhardness Measurements in B₆O

Figure 6

A bilogarithmic plot of the hardness calculated according to (5) plotted against the measured indentation diagonal length. The slope of the plot equals 𝐷_𝐻, a fractal dimension for hardness with respect to 𝑑. In the insert, the fractal dimensional increment 𝐷_𝐻 is plotted as a function of log𝑑. Nonlinearity of the scaling fractal dimensional suggests multifractal behaviour.
