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 ...
