“…Moreover, they pointed out that fatigue sensitivity of hardmetals is significantly dependent on microstructure, according to the compromising role played by the binder as the main toughening and fatigue susceptible agent in cemented carbides [15]. This fatigue degradation ascribed to the metallic phase, also observed from the experimental S-N data published by Sailer and co-workers [17], has been rationalized -at least partly -on the basis of the cyclic strain-induced fcc to hcp phase transformation within the Co binder [10,11]. Consequently, the use of alternative binders with different chemical nature (e.g.…”

“…The value of TRS is higher for the alloys with higher binder content that is equivalent to the lower volume fraction of the carbide phase V V on the decreasing side of the dependence, but the volume fraction V V makes almost no difference on the increasing side of the dependence (Figure 8). Alternatively, TRS also shows dependence with maximum against the binder content for the fixed size of the carbide grains that essentially reflects the same dependence due to the stereological relation (22) and the experimental correlation (48) (Osterstock & Chermant, 1983;Sailer, Herr, Sockel, et al, 2001).…”
