Ti/B_4C Composites Prepared by In Situ Reaction Using Inductive Hot Pressing

摘要

In the present work, in situ reinforced titanium composites (TMCs) synthesized using inductive hot pressing (iHP) are studied. The effects of B_4C phases and applied processing conditions, on the microstructure and properties of TMCs, are investigated. With the addition of B_4C particles, the microstructure of TMCs is refined and the strength is improved.Products of reactions which occur during the manufacturing process are analysed in detail. Microstructure observation illustrates, that B_4C survives - depending on the processing conditions. The reinforcing phases are homogeneously distributed in Ti matrix. Moreover, results of densification, mechanical properties and hardness measurements help to identify the most suitable processing conditions to produce this kind of TMCs.
