ball milling aluminas
Microstructure and Mechanical Properties of Carbon ...
The ball milling performed in the present study is for lower milling times (1 h) to mix Al and CNH powders. Higher ball milling times enhance the formation of Al 2 O 3. In general, XRD detects the phase of material if the amount of phase is around 5 vol.%. However, in our experiment, the maximum amount of CNH added to Al matrix is 0.8 wt ...
