ABSTRACTA range of Fe-Mn and Fe-Ni steels have been processed by melt extraction to give fibres and particulate. The consolidation and sintering performance of these alloys are presented. Densities of up to 95% can be achieved with hardnesses in the range 400–500 Hv while possessing grain sizes less than 20μm. Salient features of the sintered structures are described and it is concluded that sintering of pre-annealed short fibres compares favourably with a more conventional approach using powders.
