2018-11-13 The top–down approach of mechanical ball milling/alloying is the most commonly adopted route towards materials development. It is however surprising that despite the large impact that it has, process induced contamination (particularly from process control agents (PCAs)), remains less studied and often ignored.

2018-7-4 Yttria-reinforced copper matrix composites were prepared by dry ball milling (DBM) and wet ball milling (WBM), respectively, followed by spark plasma sintering (SPS). It is to determine which milling process is better for fabricating Cu–Y2O3 composites. It is found that Cu–Y2O3 composites synthesized by DBM exhibit better densification, mechanical and electrical properties than those by WBM.

Wet-jet milling process was employed to modify the properties of Al2O3 slurry after ball milling. Particle size distribution of slurry wet-jet milled after ball milling corresponded to that of ball-milled slurry. However, the viscosity of ball-milled slurry increased rapidly with time, whereas the viscosity of the slurry wet-jet milled after ball milling was stable for long times.

2017-5-25 The choice between wet and dry milling is, in general, unimportant in small-scale milling but is a major technical problem when large-scale milling in the metallurgical industries is involved. On purely mechanical grounds it is difficult to see any great difference in fundamental principles between wet and dry milling, since dry milling may be regarded as wet milling with a fluid having the ...
