摘要: Fractal dimension has been considered as a measure of fracture surface roughness materials. Three-dimensional (3D) analysis is anticipated to provide better evaluation toughness and fractal dimension. The objective this study was quantify the surfaces identify potential relationship between in new type core–shell titanium–iron particulate reinforced hydroxyapatite matrix composites using SEM stereoscopy coupled with 3D analysis. obtained results showed that both increased increasing amount Ti–Fe reinforcing particles. observed be direct roughness. linearly square root dimensional increment (i.e., followed Mecholsky–Mackin equation well) due presence particles along effect porosity brittle suggested proper tool for quantifying linking microstructural parameter toughness.
