Mechanics and mechanisms of fatigue in a WC-Ni hardmetal and a comparative study with respect to WC-Co hardmetals
TL;DR: In this paper, the fatigue crack growth (FCG) behavior and fatigue limit of Ni-base cemented carbides is assessed and an analysis of the results within a fatigue mechanics framework permits to validate the effective fracture toughness under cyclic loading.

Implementation of an effective time-saving two-stage methodology for microstructural characterization of cemented carbides
TL;DR: In this article, a two-stage methodology for microstructural characterization of hardmetals is presented, which involves an experimental assessment of grain size on processed images corresponding to a series of WC-Co and WC-Ni cemented carbide grades with different micro-structural characteristics.
Microstructural effects on the R-curve behavior of WC-Co cemented carbides
TL;DR: In this paper, the influence of microstructure on the R-curve behavior of hardmetals and its implication on their strength and reliability is studied, and an already validated model for R-Curve description is implemented for rationalizing the fracture behavior of five microstructurally different WC-Co cemented carbides.

Contact damage and residual strength in hardmetals
Alexey Goez,D. Coureaux,A. Ingebrand,B. Reig,E. Tarrés,A. Mestra,Antonio Mateo,Emilio Jiménez-Piqué,Luis Llanes +8 more
TL;DR: In this paper, the authors evaluated the contact response of three cemented carbides with different micro-structural features and found that strength retention is improved as contact damage mode goes from brittle to quasi-plastic, a transition directly dependent on microstructure.

Strength and reliability of WC-Co cemented carbides: Understanding microstructural effects on the basis of R-curve behavior and fractography
J.M. Tarragó,D. Coureaux,D. Coureaux,Yadir Torres,Emilio Jiménez-Piqué,L. Schneider,J. Fair,Luis Llanes +7 more
TL;DR: In this paper, the authors evaluated the strength behavior of a series of experimental WC-Co grades on the basis of R-curve failure criteria and found that microstructural effects on the strength of hardmetals may be satisfactorily rationalized following the referred criterion.
