Influence of the rate at which energy is applied to aluminum powder during its ball milling is investigated. Rolling granulation is a main process due to which treated particles achieve their unique morphology and microstructure. Drastic temperature rise at rapid ball milling leads to increase in plasticity and local melting of treated powder particles that result in their adherence to the ...

the influence of particle size on antimicrobial activities and their functional properties. The increase in ball ratio and milling time periods leads to a decrease in nanoparticle size from 114 to 45 nm which in turn increases the antimicrobial activities.

planetary ball milling under different conditions. The influence of high-energy milling time and milling speed on particle size was investigated. Furthermore, the chemical composition and densification of the calcined powders were investigated. The milled powders were calcined at 1200 °C for 2 h and then characterized via phase analysis.

The basic parameters, which influence the surface tomography, are the spindle speed (N), the axial (t z) and the radial (t xy) depth of cut, the feed rate (f z) of the cutting tool, and also the inclinations φ and ω of the tool against the processed surface and the feed direction.The present paper deals with the determination of the surface roughness (R z) in ball end milling of Al 7075-T6 ...

The influences of ball-milling time of synthesized powders and sintering temperature were investigated systematically. It is found that the samples with the maximum converse piezoelectric coefficient ( d* 33 = 266 pm/V) and the highest macroscopic remnant polarization ( P r = 15.7 μC/cm 2 ) were obtained when the ball-milling time was 32 h and ...
