The additions of 2-17wt.%Mo into iron leads to the improvement of TiB2 wetting. It has been determined that zero contact angles are formed at the wetting of TiB2 with (Fe-13wt.%Mo) and (Fe-17wt.%Mo) alloys. That is why these alloys are considered as promising metallic binder for new TiB2-based composite materials. It has been shown that there is chemical interaction between components of TiB2-(Fe-13%wt.Mo) system resulting in the formation of new complex boride phases. Hereby in this system the brittle intermetallic phases are not formed. However, the intensive formation of Fe3Mo2 intermetallics leads to the appearance of lot of cracks in the TiB2-(Fe-17wt.%Mo) system. It means that presence of brittle intermetallic phases results in the metal phase embrittlement and can lead to the deterioration of the composite material properties. The results have shown that TiB2-(Fe-13%мас.Mo) system is proved to be an optimal one for the development new composite materials. Taking into account the formation of new boride phases it is recommended to introduce 60-80wt.%(Fe-13%мас.Mo).
