    • Assessment of mechanical properties at microstructural length scale of Ti(C,N)–FeNi ceramic-metal composites by means of massive nanoindentation and statistical analysis 

      Besharatloo, H.; Nicolás Morillas, Maria de; Roa Rovira, Joan Josep; Dios Pérez, Miguel de; Mateo García, Antonio Manuel; Ferrari, Begoña; Gordo Odériz, Elena; Llanes Pitarch, Luis Miguel (2019-01-01)
      Article
      Open Access
      It is well known the interest of the scientific community in substituting the traditional cemented carbides (WC–Co) by alternative ceramic-metal systems. In this regard, Ti(C,N)-based cermets arise as excellent candidates ...
    • Carbon addition effects on microstructure and small-scale hardness for Ti(C,N)-FeNi cermets 

      Besharatloo, H.; Nicolás Morillas, Maria de; Wheeler, J.M.; Mateo García, Antonio Manuel; Ferrari, Begoña; Gordo Odériz, Elena; Llanes Pitarch, Luis Miguel; Roa Rovira, Joan Josep (2019-12-01)
      Article
      Open Access
      The current study investigates the influence of carbon addition on the microstructural and micromechanical properties of Ti(C,N)-FeNi cermets with different ceramic/metal phase ratios. Evaluation of small-scale hardness ...
    • Characterization of interfaces between TiCN and iron-base binders 

      Alvaredo, P; Roa Rovira, Joan Josep; Jiménez Piqué, Emilio; Llanes Pitarch, Luis Miguel; Gordo Odériz, Elena (2017-02-01)
      Article
      Open Access
      This work includes a study of the interface between matrix and reinforcement in Fe-Ti(C,N) systems. A study of wettability and solubility between metal and ceramic phases is first performed. It combines wetting experiments ...
    • Design of alternative binders for hard materials 

      Nicolás, M. de; Besharatloo, Hossein; Alvaredo Olmos, Paula; Roa Rovira, Joan Josep; Llanes Pitarch, Luis Miguel; Gordo Odériz, Elena (2020-02-01)
      Article

      In the last years, a special interest has emerged towards the total or partial substitution of traditional cemented carbides composing elements. In this study, a systematic methodology is presented and used to design ...
    • Influence of carbon content on microstructure and properties of a steel matrix cermet 

      Alvaredo Olmos, Paula; Bruna Escuer, Pere; Crespo Artiaga, Daniel; Gordo Odériz, Elena (2018-09-01)
      Article
      Open Access
      There is a marked correlation between the composition, microstructure and properties in TiCN-based cermets. In the case of using iron alloys as metallic matrix the carbon content is of particular significance, as not only ...
    • Influence of the processing route on the properties of Ti(C,N)-Fe15Ni cermets 

      Nicolás Morillas, Maria de; Besharatloo, Hossein; Wheeler, J.M.; Dios Pérez, Miguel de; Alvaredo Olmos, Paula; Roa Rovira, Joan Josep; Ferrari, B; Llanes Pitarch, Luis Miguel; Gordo Odériz, Elena (2020-02-01)

      This study aims to understand the influence of powder preparation and processing steps on the microstructure and properties of Ti(C,N)-Fe15Ni cermets with 70 and 80 vol% of ceramic phase. Two routes were used for powder ...
    • Micromechanics of Ti(C,N)-FeNi composites: statistical analysis and flow stress determination for the FeNi binder 

      Besharatloo, H.; Roa Rovira, Joan Josep; Dios, M.; Mateo García, Antonio Manuel; Ferrari, M.; Gordo Odériz, Elena; Llanes Pitarch, Luis Miguel (2017)
      Conference report
      Open Access
      The outstanding mechanical and tribological properties exhibited by cemented carbides results from the combination of two phases with different local properties. However, direct assessment of the small-scale response of ...
