    Nickel is one of the materials most commonly used as a binder alternative to cobalt in cemented carbides. However, knowledge on mechanical properties and particularly on fatigue response of nickel-base cemented carbides ...
  • FIB/FESEM experimental and analytical assessment of R-curve behavior of WC-Co cemented carbides 

    Tarragó Cifre, Jose María; Jiménez Piqué, Emilio; Schneider, Ludwig; Casellas Padró, Daniel; Torres, Y.; Llanes Pitarch, Luis Miguel (2015-10-01)
    Article
    Open Access
    Exceptional fracture toughness levels exhibited by WC-Co cemented carbides (hardmetals) are due mainly to toughening derived from plastic stretching of crack-bridging ductile enclaves. This takes place due to the development ...
  • Fracture and fatigue behavior of a WC-Ni cemented carbide 

    Tarragó Cifre, Jose María; Ferrari, Claudio; Reig, Blanca; Coureaux Mustelier, David; Schneider, Ludwig; Llanes Pitarch, Luis Miguel (2013)
    Conference report
    Restricted access - publisher's policy
    Nowadays, one of the main research areas in cemented carbides is focused on the replacement of cobalt as a binder for more economical materials with similar or improved properties. Nickel is one of the materials most ...
  • Fracture and fatigue behavior of cement carbides:3D focused ion beam tomography of crack-microstructure interactions 

    Tarragó Cifre, Jose María; Jiménez Piqué, Emilio; Turón Viñas, Miquel; Rivero, Lorenzo; Al-Dawery, Ihsan; Schneider, Ludwig; Llanes Pitarch, Luis Miguel (2014-09-01)
    Article
    Open Access
    The fracture and fatigue phenomena in WC-cobalt cemented carbides (hard-metals) have been subjects extensively investigated in the last 30 years. From these studies, it is well established that the metallic binder phase ...
  • Mechanics and mechanisms of fatigue in a WC-Ni hardmetal and a comparative study with respect to WC-Co hardmetals 

    Tarragó Cifre, Jose María; Ferrari, Claudio; Reig, Begoña; Coureaux Mustelier, David; Schneider, Ludwig; Llanes Pitarch, Luis Miguel (2015-01-01)
    Article
    Open Access
    There is a major interest in replacing cobalt binder in hardmetals (cemented carbides) aiming for materials with similar or even improved properties at a lower price. Nickel is one of the materials most commonly used as a ...
  • Microstructural influence on the fatigue behaviour of cemented carbides 

    Tarragó Cifre, Jose María; Schneider, Ludwig; Al-Dawery, Ihsan; Llanes Pitarch, Luis Miguel (2015)
    Conference report
    Open Access
  • Strength and reliability of WC-Co cemented carbides: understanding microstructural effects on the basis of R-curve behavior and fractography 

    Tarragó Cifre, Jose María; Coureaux Mustelier, David; Torres Hernández, Yadir; Jiménez Piqué, Emilio; Schneider, Ludwig; Fair, Jonathan; Llanes Pitarch, Luis Miguel (2018-02)
    Article
    Open Access
    Strength and reliability of WC-Co cemented carbides (hardmetals) are dependent on effective fracture toughness as well as on nature, size and distribution of processing flaws. Regarding toughness, they exhibit a crack ...
  • Toughening and fatigue micromechanisms in hardmetals: SEM/FIB tomography characterization 

    Tarragó Cifre, Jose María; Jiménez Piqué, Emilio; Turón Viñas, Miquel; Rivero, Lorenzo; Schneider, Ludwig; Llanes Pitarch, Luis Miguel (2013)
    Conference report
