Fecha de publicación: | 2019 | Editor: | Multidisciplinary Digital Publishing Institute | Citación: | Metals 9 (2019) | Resumen: | 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)B and (Ti,Ta)B, was observed. Moreover, the nature of the binder was also modified, from the (Ti,Ta)Co brittle intermetallic compound (for cermets without boron addition) to ductile and tough (Ti,Ta)Co and α-Co phases (for cermets with boron addition). These modifications caused, as a general trend, the increase of hardness and toughness in cermets. | Versión del editor: | http://dx.doi.org/10.3390/met9070787 | URI: | http://hdl.handle.net/10261/203752 | DOI: | 10.3390/met9070787 | Identificadores: | doi: 10.3390/met9070787 issn: 2075-4701 |
