The results show that:(1) after MA for 20h, single phase bcc nanocrystalline supersaturate solid solution formed in Fe84Nb7B9 and Fe80Ti8B12 alloys; the thermal stability of nanocrystalline microstructure in Fe80Ti8B12 alloy was improved significantly than that in Fe84Nb7B9 alloy, and the decomposition temperature of supersaturate solid solution decreased in Fe80Ti8B12 alloy.(2) under 30MPa/900℃/0.5h hot-press sintering conditions, the relative density of Fe84Nb7B9 and Fe80Ti8B12 bulk alloys were 96.7% and 95.5%, respectively. Compared with Fe84Nb7B9 alloy (muti-phase microstructure), Fe80Ti8B12 alloy was composed of superfine crystalline (50~200nm) of single phase α-Fe;(3) the magnetic properties of Fe80Ti8B12 bulk alloy σ(subscript s=198.6emu/g, H=54.6Oe were more excellent than that of Fe84Nb7B9 bulk alloy σ(subscript s=162.9emu/g, H=105.1G, it was related to the different phases formed during hot-press sintering and the grain size of nanocrystalline powder.
