dc.description.abstract | In this work, a titanium–tantalum carbonitride based cermet, with cobalt as the binder phase
and boron as a sintering additive, was developed by a mechanically induced self-sustaining reaction
process using two different methodologies. The boron additive was added to prevent the formation of
brittle intermetallic compounds generally formed during the liquid phase sintering step due to the
excessive ceramic dissolution into the molten binder phase. A systematic study was carried out to
understand the effects of boron addition on the nature of the phases, microstructure, and mechanical
properties of cermets. With the boron addition, the formation of two different boride solid solutions,
i.e., (Ti,Ta)B2 and (Ti,Ta)3B4, was observed. Moreover, the nature of the binder was also modified, from
the (Ti,Ta)Co2 brittle intermetallic compound (for cermets without boron addition) to ductile and tough
(Ti,Ta)Co3 and -Co phases (for cermets with boron addition). These modifications caused, as a general
trend, the increase of hardness and toughness in cermets. | es |
