MULTICOMPONENT SOLID-SOLUTIONS ON THE BASIS OF IRON BORIDE FE2B

It is well known that the hardness of iron alloys are increased remark ably by the addition of boron. The properties of such alloys may be op timized by using alloying elements like Cr, Mn, Si and Al. Formation o f binary, ternary and multicomponent solid solution on the basis of Fe 2B were studied. Investigation of mechanical properties indicated the increase of hardness and decrease of brittleness of iron boride owing to formation of multicomponent solid solution on the basis of(Fe, Cr, Mn, Si, Al)(2) (B, C).
