Microstructure and soft magnetic properties of bulk amorphous and/or nanocrystallineFe73.5Cu1Nb3Si13.5B9(Finemet) alloys prepared by consolidation at a ultra-high pressure (5.5GPa)were investigated in this paper. The relative density of the bulk sample 1 (from amorphous powders)was 98.5% and the grain sizes were about 10.6nm. While the relative density and grain sizes of bulksample 2 (from nanocrystalline powders) are 98% and 20.1nm, respectively. Particularly, the bulksamples exhibited a good combined magnetic property: for Sample1, Ms=125emu/g and Hc=1.5Oe;for Sample2, Ms=129emu/g and Hc=3.3Oe. The success of synthesizing the nanocrystallineFe-based bulk alloys will be encouraging for the future development of bulk nanocrystalline softmagnetic alloys
