抄録

The microstructure formation and mechanical properties of sintered materials based on the prealloyed Fe-1.5wt%Mo powder with 0.2-0.6 wt% of boron addition are investigated.An eutectic liquid phase Fe+Fe₂B activating the sintering of Fe-1.5Mo+B powder systems is formed. Besides this, an interaction of boron with the Fe-Mo prealloyed matrix occured and the formation of fine particles containing molybdenum and boron was registered. Due to this interaction the decrease of eutectic phase portion and strengthening of the matrix by borides was occurred. The materials Fe-1.5Mo+0.4wt%B achieved the tensile strength Rm=487 MPa, the elongation A₅=2.5 % and the hardness of 212 HV 30 at the density of 7.15 g·cm^-3 after sintering at 1 200° for 30 min.
