..., and metallurgical analyses. SEM imaging revealed microvoid coalescence within the fracture zone. The microvoids were flat and smooth edged indicating insufficient bonding. In addition, a cross sectional sample, mounted and etched using alkaline chromate, revealed an oxygen-rich zone in the jaw. It was concluded...

... microvoid coalescence in an elongated condition as shown in Figure 6 . The final progression was to a quasi-cleavage condition, Figure 7 . Just prior to the quasi-cleavage condition, well established microvoid coalescence with very little shear was also present on the failure surface. The second exemplar...

... generally exhibit a macroscopic “cup and cone” morphology. Higher magnification SEM examination reveals microvoid coalescence (dimpled rupture) fracture morphology. The cup and cone and microvoid coalescence occurs at temperatures between −196 and 500 °C. This result is consistent with the observations...
