Correlation between surface damage and mechanical properties at micro- and nanometric length scale for WC-Co hardmetals
(Universitat Politècnica de Catalunya, 2014-10)
Projecte/Treball Final de Carrera
Accés obertCemented carbides (WC-Co) are ceramic-metal composite materials made by hard tungsten carbide particles bonded through a metallic binder matrix, mainly of cobalt. It is a hard material characterized by an exceptional ... -
FIB/FESEM experimental and analytical assessment of R-curve behavior of WC-Co cemented carbides
(2015-10-01)
Article
Accés obertExceptional fracture toughness levels exhibited by WC-Co cemented carbides (hardmetals) are due mainly to toughening derived from plastic stretching of crack-bridging ductile enclaves. This takes place due to the development ... -
Influència de la microestructura en el dany induït per corrosió en els carburs cementats
(Universitat Politècnica de Catalunya, 2015-11)

Intrinsic hardness of constitutive phases in WC–Co composites:Nanoindentation testing, statistical analysis, WC crystal orientation effectsand flow stress for the constrained metallic binder
(Elsevier, 2015-11-03)
Article
Accés obertThe intrinsic hardness of the constitutive phases in WC–Co composites is investigated by combining experimental and statistical analysis nanoindentation techniques. It is done on the basis of considering the cemented carbide ... -
Intrinsic hardness of the individual constitutive phases (carbides and binder) of cemented carbides
(Universitat Politècnica de Catalunya, 2015-06)
Projecte Final de Màster Oficial
Accés restringit per decisió de l'autorHardmetals 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 ... -
Mechanical deformation of WC–Co composite micropillars under uniaxial compression
(2015-07-17)
Article
Accés obertIn thiswork,WC–Co micropillars machined by focused ion beamhave been tested under uniaxial compression to investigate the stress–strain behavior and associated deformation mechanisms. The results indicate that yielding ... -
Scale effect in mechanical characterization of WC-Co composites
(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 ...
