dc.description.abstract | In the last decade, titanium metal matrix composites (TMCs) have received considerable
attention thanks to their interesting properties as a consequence of the clear interface between
the matrix and the reinforcing phases formed. In this work, TMCs with 30 vol % of B4C are
consolidated by hot pressing. This technique is a powder metallurgy rapid process. Incorporation of
the intermetallic to the matrix, 20 vol % (Ti-Al), is also evaluated. Here, the reinforcing phases formed
by the reaction between the titanium matrix and the ceramic particles, as well as the intermetallic
addition, promote substantial variations to the microstructure and to the properties of the fabricated
composites. The influences of the starting materials and the consolidation temperature (900 C
and 1000 C) are investigated. By X-ray diffraction, scanning and transmission electron microscopy
analysis, the in-situ-formed phases in the matrix and the residual ceramic particles were studied.
Furthermore, mechanical properties are studied through tensile and bending tests in addition to other
properties, such as Young’s modulus, hardness, and densification of the composites. The results show
the significant effect of temperature on the microstructure and on the mechanical properties from
the same starting powder. Moreover, the Ti-Al addition causes variation in the interface between
the reinforcement and the matrix, thereby affecting the behaviour of the TMCs produced at the
same temperature. | es |
