The results show that the average absolute value of relative errors between predictive and measured values of hardness is 5.90%, the prediction accuracies of adhesion and impact resistance are 100%.
The results showed that the relative density and Brinell hardness decreased while the electrical resistivity increased with the increase of graphite content.
