... because of an intergranular fracture mechanism initiated at the carbides-rich interface. This mechanism was consistently observed for specimens with fatigue precrack fronts in the hard layer. To model the brittle behavior of the MA interface, the stress distributions on the MA interface were calculated...

... found that in the case of uniaxial stretch continuous failure elements appeared on the grain boundary perpendicular to the stretching direction, closest to the loading surface. This led to the formation of the so-called intergranular fracture ‘crack’. The simulation results showed that as the uniaxial...
