In the present work, in situ reinforced titanium composites (TMCs) synthesized using inductive hot pressing (iHP) are studied. The effects of TiAl and B4C phases and applied processing conditions, on the microstructure and properties of TMCs, are investigated. With the addition of B4C particles, the microstructure of TMCs is refined and the strength is improved. TiAl phases are formed during the processing and the influence as mechanism for the strengthening of the matrix are evaluated. Products of reactions which occur during the manufacturing process are analysed in detail. Microstructure observation illustrates, that B4C survives - depending on the processing conditions. The reinforcing phases are homogeneously distributed in Ti matrix. On contrary, TiAl is formed during the iHP process even at short processing time. Moreover, results of densification, mechanical properties and hardness measurements help to identify the most suitable processing conditions to produce this kind of TMCs.
