“…The problem has been overcome applying two main strategies. One option entails the addition of secondary carbides, such as Mo2C [76,[144][145][146][147][148] or WC [76,144,[146][147][148][149]. Another approach is the inclusion of other alloying elements, like Ni [40,150].…”

Estos cuatro años han sido todo un aprendizaje, tanto en el plano profesional como en el personal. Y durante esta trayectoria me han acompañado personas sin las cuales no habría logrado esta ansiada meta y a las que me gustaría dar las gracias.En primer lugar, a mis directores de tesis, Elena y Luis. Gracias por vuestro tiempo y guía durante esta carrera de fondo. He aprendido de vosotros en muchísimos aspectos, me habéis enseñado a volar sola sin dejar de estar cuando lo he necesitado. Gracias por vuestro apoyo y por los muchos congresos a los que hemos ido juntos. Guardo con especial cariño en mi memoria el de Tailandia, con celebración de cumpleaños incluida.A Irene Fernández Villegas y José Manuel Torralba, porque con vosotros empezó la locura de la investigación. Irene, te agradeceré siempre el enseñarme a valorarme tanto a mí misma como a mi trabajo.A mi grupo de investigación en Madrid -GTP -por el buen trato, ambiente y apoyo. En especial a Toñi,

“…Additions of secondary carbides or carbide formers like Mo, lead to an increase in the TRS values compared to grades without these additions [71-73, 75, 76, 78, 79, 83, 102]. According to Rahimi et al [70], Mo 2 C is more effective than WC or (Ta 0.7 Nb 0.3 )C in increasing the TRS. N 2 atmosphere is generally not beneficial for the TRS, especially if added before the cooling stage.…”

The paper describes briefly the historical development and presents in more detail solid-state properties such as hardness, heat conductivity, thermal expansion and mechanical properties of titanium carbonitride Ti (C,N), the basis of the hard phase of cermets. The metallurgy of Ti (C,N)-based cermets with respect to microstructure formation during sintering and the impact on properties are presented in more detail. The various influences such as W and/or Mo content, Mo/W ratio, C content and C/N ratio, binder phase content and binder phase composition (Co/Ni), sintering time, dwell time, alloy state of powders and grain size were critically evaluated and are presented in form of fracture toughness vs. hardness graphs. A table gives a reference list on the study of these influences. TRS data on cermets were collected and summarised in a separate table, too. The focus is put on grades which have the potential of being fabricated soon in industrial processes for production of cermet tools. Application examples for metal cutting, sawing and chip bonding are presented. In two final sections recent modifications and achievements such as graded microstructures, multicomponent binder, and hybrid microstructures are also briefly presented together with an outlook on the future potential of cermet applications.

“…Some metal carbides (e.g. WC, NbC, Mo2C, TaC) are normally added to improve not only the performance but also the processing, by improving the wettability between the ceramic and the liquid phase, as well as enhance density and decrease particle growth rate (Li et al, 2008;Rahimi et al, 2007). Those additions are necessary to overcome the poorer processing of TiCN cermets with respect to the cemented carbides, which is one of their disadvantages, others being lower toughness and poorer thermal shock resistance.…”

This work is focused on the cutting performance of a new cermet based on high-speed steel (HSS) matrix with hard phase TiCN. The processing route to manufacture the cermet M2 + 50 vol.% TiCN is described. Orthogonal cutting tests, carried out in a lathe showed the ability of the new cermet to achieve turning operations, showing reasonably wear resistance performing dry cutting operations. Tool life was significantly increased, when the cermet was compared with the reference material M2 without reinforcement and with commercial HSS M2. Evolution of flank wear and chipping wear, being the dominant wear patterns, were analysed.
