That procedure highlighted discrepancies in specimens, caused by different debonding conditions.
This result could be explained by the polymicrobial aspect of these specimens caused by the presence of oral bacterial flora, which was proven by the high number of bacteria identified from each specimen (Table 1).
Fatigue specimens were tested with and without cooling air to determine the effects of increased specimen temperature caused by internal damping due to cycling at a very high frequency.
Deposits of hemosiderin were noted throughout the specimen, possibly caused by bleeding after rupture of the tendon.
It is considered that the decrease of plastic deformability for the notched specimen was caused by the process of voids formation and crack growth due to the effect of plastic constraint of the notch.
It is suggested that the very small thermal expansion coefficient in the as-rolled specimen is caused by the preferential growth of the nanodomain variant due to residual stress.
Regardless of the imaging modality, scoring of detailed morphological or cellular phenotypes is often complicated by inconsistent orientation of specimen, mainly caused by their complex three-dimensional shape.
The failure of these specimens was caused by cyclic creep/ratcheting rather than fatigue cracking.
Using the above experimental results, it has been concluded that the graded structure appearing in the eutectic specimen must be caused by the difference in the densities between Al and Cu in liquid state.
