Structural Evolution of Al-20% (wt) Al2O3 System during Ball Milling Stages
Production of nanostructured aluminum matrix composite powder by high energy ball milling is investigated. Scanning electron microscopy analysis as well as the tap and green density measurements were used to optimize the milling time needed for the completion of the mechanical milling process. Also, we studied the particles morphology and size distribution change with milling time and its corre...
متن کاملMECHANICAL PROPERTIES OF DENTAL COMPOSITE MATERIALS REINFORCED WITH MICRO AND NANO-SIZE Al2O3 FILLER PARTICLES
Abstract: Composite specimens were prepared by dispersion of various amounts of nano-sized Al2O3 fillers in a monomer system containing 60% Bis-GMA and 40% TEGDMA. For comparative purposes, composite samples containing micrometer size Al2O3 fillers were also prepared following the same procedure. The mechanical properties of the light- cured samples were assessed by three-point flexural strengt...

متن کاملan investigation into the wear behaviour of aluminum (aa2124) matrix composite reinforced with intermetallic mosi2 particles
in the present work, the aa2124/25vol.%mosi2 composite was produced by powder metallurgy technique. the aluminum alloy 2124 powder was produced by gas atomization method and the mosi2 intermetallic particles were produced through combustion synthesis. the aa2124 matrix powder was mechanically blended with 25vol.%mosi2 using a ball milling mixer. the blended powder mixture was encapsulated and t...
متن کاملEffect of Mechanical Milling on the Morphologyand Structural Evaluation of Al-Al2O3 Nanocomposite Powders
The morphological and microstructural changes during mechanical milling of Al powder mixed with 2.5, 5 and 10 wt.% Al2O3 particles were studied. The milling was performed in a planetary ball mill for various times up to 20 h. The produced composite powders were investigated using X-ray diffraction pattern (XRD) to elucidate the role of particle size, secondary phase content and milling time on ...
