[ 1 ] - Experimental and Finite Element Simulation of Nano-indentation on Metal Matrix Composites: Hardness Prediction
The scientific importance of nanocomposites are being increased due to their improvedproperties. This paper is divided into two parts. First, Al-Al2O3 nanocomposite wasproduced by using ball milling technique followed by cold compaction and sintering.Microstructure and morphology studies were done through SEM, TEM, and EDX anal-ysis on the produced powder. The mechanical properties of the produ...
[ 2 ] - Effect 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 ...
