Structural and microstructural properties of in-situ alumina-titania-graphite hybrid nanocomposite via low energy milling
This study was conducted to investigate the effect of variation milling time and compaction pressure on structural and microstructural of in situ Al2O3–TiO2-graphite nanocomposite using powder metallurgy route. Elemental powders of Al2O3 (alumina) TiO2 (titania) and graphite (C) were milled in a low...
