      Realitzat a/amb:   Luleå tekniska universitet
      In the last decades there has been growing interest in developing ceramic materials with high fracture toughness (Klc) and strength for structural applications. In the specific case of 3 mol% yttria-doped tetragonal zirconia ...

    • Surface microstructural changes of spark plasma sintered zirconia after grinding and annealing 

      Melk, Latifa; Mouzon, Johanne; Turón Viñas, Miquel; Akhtar, Farid; Antti, Marta-lena; Anglada Gomila, Marcos Juan (2016-11-01)
      Article
      Accés obert
      Spark plasma sintered zirconia (3Y-TZP) specimens have been produced of 140 nm 372 nm and 753 nm grain sizes by sintering at 1250 °C, 1450 °C and 1600 °C, respectively. The sintered zirconia specimens were grinded using a ...

    • The influence of unshielded small cracks in the fracture toughness of yttria and of ceria stabilised zirconia 

      Melk, Latifa; Turón Viñas, Miquel; Roa Rovira, Joan Josep; Antti, Marta-Lena; Anglada Gomila, Marcos Juan (Elsevier, 2016-01-01)
      Article
      Accés restringit per política de l'editorial
      The fracture toughness, Ric of two 3Y-ZrO2 with different grain size (177 and 330 nm) and 12Ce-ZrO2 were determined from a sharp micro-machined notch by Ultra-Short Pulsed Laser Ablation (UPLA) where a micro-cracked zone ...
