Addition of Fe B C and Fe Mo B C m aster alloy pow ders to Fe Mo B Csintered steels can ac tivate the sintering process by liquid phase sintering . The for m ation of liquid ( α- Fe + ( Fe , Mo) 2 B+ Fe3( B, C) → L) i m proves m echanical properties of the steels , and ultim ate tensilestrengths of 684 774 M Pa , i m pact energy of 47 ±7 Jand elongation of 2 5 ±0 9 were ob tained . Optim u m a mount of liquid phase exists , and alarge a mount of liquid phase will re sult in the form ation of continuous netw ork of liquid phase that is detrim ental to strength andelongation .
