      Article
      Accés obert
      A deep knowledge of micromechanical properties of each constitutive phase of cemented carbides is crucial to improve their performance on the basis of microstructural design optimization. In the present work, a systematic ...
    • Microstructural influence on tolerance to corrosion-induced damage in hardmetals 

      Tarrago, J.M.; Fargas Ribas, Gemma; Isern, Lluis; Dorvlo, Selassie; Tarrés, E.; Muller, Carlos; Jiménez Piqué, Emilio; Llanes Pitarch, Luis Miguel (2016)
      Article
      Accés obert
      The influence of the microstructure on the tolerance of WC-Co cemented carbides to corrosion damage was studied by using residual strength as the critical design parameter. In doing so, samples were immersed in synthetic ...
    • Small scale mechanical response of WC-Co cemented carbides 

      Roa Rovira, Joan Josep; Jiménez Piqué, Emilio; Sandoval, Daniela A.; Tarrago, Jose María; Fair, Jonathan; Tarrés, E.; Llanes Pitarch, Luis Miguel (2017)
