Estimación del límite de fatiga de carburos cementados WC-Co en el marco de la mecánica de la fractura elástica lineal
(Sociedad Española de Cerámica y Vidrio, 2004)
En este trabajo se investiga el comportamiento a fractura y fatiga de dos grados de carburos cementados WC-Co con distintos contenidos de fase ligante y tamaño de carburo medio. La caracterización mecánica incluye la ...

Strength and reliability of WC-Co cemented carbides: Understanding microstructural effects on the basis of R-curve behavior and fractography
(Elsevier, 2018)
Strength and reliability of WC-Co cemented carbides (hardmetals) are dependent on effective fracture toughness as well as on nature, size and distribution of processing flaws. Regarding toughness, they exhibit a crack ...

FIB/FESEM experimental and analytical assessment of R-curve behavior of WC-Co cemented carbides
(Elsevier, 2015)
Exceptional 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 ...

Influence of temperature on the biaxial strength of cemented carbides with different microstructures
(Elsevier, 2018)
The effect of the temperature on the mechanical strength of WC-Co cemented carbides with different microstructures (grain size and binder content) was evaluated. Biaxial flexural tests were performed on three cemented ...
