Damage indicators for early fatigue damage assessment in WC-Co hardmetals under uniaxial cyclic loads at a stress ratio of R = −1 at elevated temperatures

Could an amorphous binder Co phase improve the mechanical properties of WC–Co? A study of molecular dynamics simulation

“…50,51 Moreover, with the increase in temperature, the disorder areas near the Co grain increase, implying more defects and a reduction in strength. 34,52,53 When the temperature is 300 K, the stacking fault marked SF1 forms and slides in grain 1, as shown in Fig. 3(a).…”

“…Moreover, with WC–Co as the tool/chip, the service conditions of applied intensive stress and high temperature need to be investigated. 33–37…”

“…Moreover, with WC-Co as the tool/chip, the service conditions of applied intensive stress and high temperature need to be investigated. [33][34][35][36][37] With this background, the effects of the amorphous binder phase on the mechanical properties of WC-Co at room and high temperatures were studied. The structural transformations and mechanical behavior during the deformation of each case have been systematically analyzed and reported in the following sections.…”
