The dependence of magnetic properties on the microstructure determined by alloy composition and preparation parameters has been studied in the mechanically alloyed Sm26Fe74-Ti-y(y) (y=0-17), Sm26Fe74-nVn (n=0-9) and Sm26Fe65Ti9-zVz (z=0-7) systems. The addition of Ti to Sm-Fe binary alloy is favourable for the formation of the hard magnetic 5:17 phase, and this phase exists in the investigated composition range (y=1-17) for Sm26Fe74-yTiy. The addition of V leads to the appearance of the 1:12 phase. The composition range for V to stabilize the 5:17 phase is very limited: n=1-5 and z=1-3 for Sm26Fe74-nVn and Sm26Fe65Ti9-zVz, respectively.
