Fatigue susceptibility under contact loading of hardmetals coated with ceramic films
Llanes Pitarch, Luis Miguel; Tarrés, E.; Ramírez, Giselle; Botero Vega, Carlos Alberto; Jiménez Piqué, Emilio (2010-04)
Article
Accés restringit per política de l'editorialThe contact fatigue behavior of a fine-grained hardmetal coated with two distinct ceramic films, either a TiN monolayer or a WC/C multilayer, is studied by means of indentation testing techniques. Spherical indentation ... -
Focused ion beam tomography of WC-Co cemented carbides
Jiménez Piqué, Emilio; Turón Viñas, Miquel; Chen, H.; Todorov Trifonov, Trifon; Fair, Jonathan; Tarrés, E.; Llanes, Angels (2017-09-01)
Article
Accés obertThe microstructure of three different grades of WC-Co cemented carbides (hardmetals) has been reconstructed in three dimensions after sequential images obtained by focused ion beam. The three dimensional microstructual ... -
Fracture and fatigue of rock bit cemented carbides: Mechanics and mechanisms of crack growth resistance under monotonic and cyclic loading
Torres, Y.; Tarragó Cifre, Jose María; Coureaux Mustelier, David; Tarrés, E.; Roebuck, C.; Chan, P.; James, M.; Liang, B.; Tillman, M.; Viswanadham, R.K.; Mingard, K.P.; Mestra Rodríguez, Álvaro Miguel; Llanes Pitarch, Luis Miguel (2014-07-01)
Article
Accés restringit per política de l'editorialIn an attempt to improve the material selection, design and reliability of rock bit WC-Co cemented carbides (hardmetals), an extensive and detailed study is conducted with the main goal of characterizing the fracture and ... -
Influencia de la microestructura en el daño inducido por corrosión en los carburos cementados WC-Co
Fargas Ribas, Gemma; Llanes Pitarch, Luis Miguel; Müller Jevenois, Carlos M.; Sosa, D.; Tarragó, Jose Maria; Tarrés, E.; Fair, Jonathan (2017)
Text en actes de congrés
Accés restringit per política de l'editorialEl presente trabajo tiene como objetivo estudiar la influencia de la microestructura en el comportamiento a corrosión de carburos cementados WC-Co (metal duro), en dos medios: agua de mar y agua de mina. Para ello, se han ... -
Micromechanical properties of WC-(W,Ti,Ta,Nb)C-Co composites
Sandoval, Daniela A.; Roa Rovira, Joan Josep; Ther, O; Tarrés, E.; Llanes Pitarch, Luis Miguel (2019-03-10)
Article
Accés obertA 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 obertThe 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)
Text en actes de congrés
Accés restringit per política de l'editorialIn recent years, many efforts have been invested to determine the intrinsic mechanical properties for each constitutive phase of composite materials. The outstanding behaviour of WC-Co composites is mainly attributed to ...
