      Rueda Arango, Astrid Oasis; Anglada, M.; Jiménez Piqué, Emilio (2015-03-01)
      Article
      Accés obert
      Objectives. To understand the resistance to cyclic and static contact loading of feldspathic porcelain on dental zirconia (3Y-TZP), in order to understand the partial failure of porcelain (chipping or cracking).; Methods. ...

    • Dependence of nanoindentation hardness with crystallographic orientation of austenite grains in metastable stainless steels 

      Roa Rovira, Joan Josep; Fargas Ribas, Gemma; Mateo García, Antonio Manuel; Jiménez Piqué, Emilio (2015-10-01)
      Article
      Accés restringit per política de l'editorial
      The mechanical behaviour of a metastable austenitic stainless steel has been studied by means of nanoindentation of individual grains. Hardness, elastic modulus and estimation of wear resistance were determined as a function ...

    • Fracture toughness of cemented carbides: Testing method and microstructural effects 

      Sheikh, Saad; M'Saoubi, Rachid; Flasar, Petr; Schwind, Martin; Persson, Tomas; Yang, Jing; Llanes Pitarch, Luis Miguel (2015-03-01)
      Article
      Accés obert
      Fracture toughness is one the most important parameters for design applications and performance assessment of WC-Co cemented carbides (hardmetals). Different from hardness, fracture toughness is commonly a property more ...

    • Mechanical properties of 12Ce-ZrO2/3Y-ZrO2 composites 

      Turón Viñas, Miquel; Roa Rovira, Joan Josep; García Marro, Fernando; Anglada Gomila, Marcos Juan (2015-12-01)
      Article
      Accés obert
      12Ce-ZrO2/3Y-ZrO2 composites with different compositions have been prepared by presureless sintering at 1450 degrees C and the resulting microstructures have been correlated with their mechanical properties in terms of ...

    • 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)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      The particular microstructure assemblage of hardmetals yields those materials an extraordinary combination of hardness and toughness. On the other hand, it is also known that these materials are prone to strength degradation ...
