Mo is investigated. It has been determined that addition of 5-9% Мо into Fe leads to the formation of metal-based matrix structure with some inclusions of Fe2Mo intermetallic phase. Structure of Fe-13%Mo alloy consists of ?-Fe solid solution and Fe3Mo2 intermetallic inclusions. Increase of molybdenum content up to 17-30%wt. results in the intensive formation of brittle Fe2Mo and Fe3Mo2 conglomerates. Thus, iron alloys containing 5-13%wt molybdenum can be used as metal binder for TiB2 composite materials. Wetting behavior of TiB2-(Fe-Mo) system was studied. It has been determined that addition of 2-17%wt. of molybdenum promotes a decrease of the contact angle of titanium diboride wetting and increase work of adhesion in the TiB2-(Fe-Mo) system. Zero contact angles are formed at the wetting of TiB2 with (Fe-13wt.%Mo) and (Fe-17wt.%Mo) alloys which proves to be a promising metal binder for TiB2-based composite material. The results of this research are intermediate and will be used in the following investigations of contact interaction in TiB2-(Fe-Мо)system to choose the metal binder optimal content for new composite material.
