摘要
The work presents the possibility of substitution of expensive, Co-WC powders, that have been traditionally used in the production of sintered diamond tools, with cheap iron-base counterparts manufactured by ball milling. It has been shown that ball-milled Fe-Ni and Fe-Mn powders can be consolidated to a virtually pore-free condition by hot pressing at 900 degrees C. The as-consolidated materials are characterised by high hardness, bending strength and resistance to 3-body abrasion.
