    • Resistencia al desgaste de aceros inoxidables austeníticos metaestables 

      Escolà, M.; Méndez, H.; Fargas Ribas, Gemma; Fargas Ribas, Gemma (EUETIB, 2014-12-01)
      Text en actes de congrés
      Accés obert
      Los aceros inoxidables austeníticos metaestables se caracterizan por presentar transformación de fase de austenita a martensita por deformación. Este fenómeno comporta un aumento del límite elástico, de la resistencia ...
    • Reversible phase transformation in polycrystalline TRIP steels induced by cyclic indentation performed at the nanometric length scale 

      Roa Rovira, Joan Josep; Sapezanskaia, Ina; Fargas Ribas, Gemma; Kouitat, R.; Redjaïmia, A.; Mateo García, Antonio Manuel (2018-09-17)
      Article
      Accés obert
      Metastable austenitic stainless steels are an interesting group of materials, which exhibit the Transformation Induced Plasticity effect. In this regard, phase transformation from austenite to martensite enhances the work ...
    • Robocasting of dense 8Y zirconia parts: Rheology, printing, and mechanical properties 

      Zhang, Junhui; Yarahmadi, Mona; Cabezas i Peñalva, Laura; Serra Fanals, Marc; Elizalde Huitrón, Sergio Alberto; Cabrera Marrero, José M.; Llanes Pitarch, Luis Miguel; Fargas Ribas, Gemma (Elsevier, 2023-07-08)
      Article
      Accés obert
      Advanced ceramics with complex geometry have become indispensable in engineering applications. Due to limitations of traditional ceramic fabrication processes, additive manufacturing represents a revolution for shaping and ...
    • Small-scale assessment of corrosion-induced damage in hardmetals 

      Zheng, Yafeng; Fargas Ribas, Gemma; Besharatloo, Hossein; Roa Rovira, Joan Josep; Lavigne, Olivier; Llanes Pitarch, Luis Miguel (2019)
      Text en actes de congrés
      Accés obert
      In this work, the effect of corrosion-induced damage on the mechanical response of hardmetals was evaluated at small-scale level by means of nanoindentation and nanoscratch. Damage was introduced in a controlled way through ...
    • Superficial effects of ball burnishing on TRIP steel AISI 301LN sheets 

      Jerez Mesa, Ramón; Fargas Ribas, Gemma; Roa Rovira, Joan Josep; Llumà Fuentes, Jordi; Travieso Rodríguez, José Antonio (Multidisciplinary Digital Publishing Institute (MDPI), 2021-01-03)
      Article
      Accés obert
      This paper explores the consequences of applying an ultrasonic vibration-assisted ball burnishing process and its non-vibration assisted version on the topology and subsurface microstructure of a transformation-induced ...
    • Synthesis and characterization of an Fe/Co ferrite spinel oxide film produced by using N2/steam heat treatment on two maraging steels 

      Cerra Flórez, Mauro Andrés; Fargas Ribas, Gemma; Roa Rovira, Joan Josep; Mateo García, Antonio Manuel; Mata, Stephany Aparecida Santos da; Rodríguez Castellón, Enrique; Silva, Marcelo José Gomes da (2022-02-09)
      Article
      Accés obert
      An experimental procedure was developed to obtain an oxide layer formed mainly by spinel on maraging steels. It consists of different stages with specific conditions, such as atmospheres rich in nitrogen and water vapor, ...
    • Transmission of plasticity through grain boundaries in a metastable austenitic stainless steel 

      Mateo García, Antonio Manuel; Sapezanskaia, Ina; Roa Rovira, Joan Josep; Fargas Ribas, Gemma; Redjaïmia, Abdelkrim (Multidisciplinary Digital Publishing Institute (MDPI), 2019-02-01)
      Article
      Accés obert
      Austenitic metastable stainless steels have outstanding mechanical properties. Their mechanical behavior comes from the combination of different deformation mechanisms, including phase transformation. The present work aims ...
