The production of high hardness and thermally stable nanocrystalline aluminium composites is described. Al powder was milled at room temperature in an ammonia flow for a period of less than 5 h. NH 3 dissociation during milling provokes the absorption, at a high rate, of nitrogen into aluminium, hardening it by forming a solid solution.

The work presents the possibility of application of inexpensive iron-base powders in the production of sintered diamond tools. It has been shown that ball-milled Fe-Ni-Cu-Sn-C and Fe-Mn-Cu-Sn-C powders can be consolidated to a virtually pore-free condition by hot pressing at 900°C. The as-consolidated materials are characterised by a combination of high hardness, …

Air classifier mills can achieve particle size reduction down to 4 to 15 microns. This depends on the mill selection and the characteristics of the material to be milled. Spray dried powders mill finer than crystalline powders. Milling is achieved by impact between a high speed rotor fitted with hammers or pins and a stationary grinding track.
