    • Ablation investigation of cemented carbides using short-pulse laser beams 

      Fang, Shiqi; Lima, Renata; Sandoval Ravotti, Daniela Andreina; Bähre, Dirk; Llanes Pitarch, Luis Miguel (Elsevier, 2018)
      Text en actes de congrés
      Accés obert
      As an excellent engineering tool material, cemented carbides are capable to shape and cut metallic materials with high surface finish quality and precision. However, in regard to conventional abrasive methods cemented ...

    • Influence of specimen size and microstructure on uniaxial compression of WC-Co micropillars 

      Sandoval Ravotti, Daniela Andreina; Rinaldi, Antonio; Notargiacomo, A.; Ther, O; Tarrés Puit, Elena; Roa Rovira, Joan Josep; Llanes Pitarch, Luis Miguel (2019-09-13)
      Article
      Accés obert
      The current interest on the development of components on the micrometer size regime demands the evaluation of the mechanical behavior at such small length scales. Regarding cemented carbides, evaluation of mechanical ...

    • Intrinsic hardness of the individual constitutive phases (carbides and binder) of cemented carbides 

      Sandoval Ravotti, Daniela Andreina (Universitat Politècnica de Catalunya, 2015-06)
      Projecte Final de Màster Oficial
      Accés restringit per decisió de l'autor
      Hardmetals are heterogeneous materials at microstructural scale, i.e. they are conformed by different phases defined by their chemical nature or their crystallographic orientation. In the present Master thesis, a WC-(Ta-Ti)C-Co ...

    • Scale effect in mechanical characterization of WC-Co composites 

      Sandoval Ravotti, Daniela Andreina; Rinaldi, Antonio; Tarragó, José María; Roa Rovira, Joan Josep; Fair, Jonathan; Llanes Pitarch, Luis Miguel (2018-04-01)
      Article
      Accés obert
      © 2017 Elsevier LtdThe study of mechanical response of materials at small length scales has gained importance due to the recent advances in micro- and nano-fabrication as well as testing systems. However, most of the ...

    • Small-scale testing of micromechanical response of cemented carbides 

      Sandoval Ravotti, Daniela Andreina (2019-11-11)
      Tesi
      Accés obert
      Cemented carbides are composite materials widely used in different industry fields within applications involving wear, due to their outstanding wear resistance. The most commonly used are WC-Co grades, for Co wettability ...

    • WC-base cemented carbides with partial and total substitution of Co as binder: Evaluation of mechanical response by means of uniaxial compression of micropillars 

      Sandoval Ravotti, Daniela Andreina; Rinaldi, Antonio; Notargiacomo, A.; Ther, O; Roa Rovira, Joan Josep; Llanes Pitarch, Luis Miguel (2019-11-01)
      Article
      Accés obert
      The influence of the chemical nature of the metallic binder on the plastic deformation of cemented carbides was studied. Three different cemented carbide grades - WC-Co, WC-CoNi and WC-NiMo - with similar microstructural ...
