Contamination in wet-ball milling: Powder Metallurgy:

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.

Amorphous and nanocrystalline Fe-Ti prepared by ball

Dolgin et al.6 reported continuous growth of an amor-phous phase by wet ball milling of elemental Fe and Ti powders (a small amount of toluene was added to the powders). Since ball milling constantly creates new bare metal surfaces, the milled material is very sensitive to the ambient atmosphere during both milling and handling.

Toward nanomechanical models of liquid-phase

The model appears to give values comparable to those obtained in wet ball milling, but to overestimate the shear rate values reported for turbulent exfoliation (by rotor mixing or microfluidization). We suggest that for turbulent exfoliation a “cleavage model” may be more appropriate, as it gives a stronger dependence on a and smaller ...
