The disorder ratio (ID/IG) for EG-m decreases from 1.1 to 0.5 as the growth temperature varied from 1350°C to 1450°C, indicating increasing grain size, while ID/IG for EG-a does not vary significantly.
This number is the same on the C-and Si faces, as the arrangement on those faces is the same.

Introduction An increasing number of demand for the simulatability of prosthesis, the aesthetic effect of dental all-ceramic materials have gradually become the research hotspot.

Note that due to the crystal and sample symmetry (Bunge [4]), each of these components appears a number of times in the ODF.
Indeed, the Taylor model does not take the heterogeneity of plastic strain inside the grains into account, and ALAMEL does it only in a limited way.

The maximum of the distribution corresponds to the most probable domain configuration and its width reflects the number of available domain states.
The fast relaxation with time constants in the order of a few seconds is attributed to the presence of a conductive grain boundary phase which should be avoided by optimizing film deposition.

Niobium acts as an inhibitor of crystal growth, increasing the crystallization temperature and ensuring the growth of crystals from a large number of centers [3].

A mechanism for ductile fracture is evident in the solution treated sample, where a large number of cells (dimples) are visible.
In addition, the pits appear to nucleate preferentially at the ferrite grains.

Out of the various numbers of joints produced using the FSW in this investigation, the joints fabricated employing a taper cylindrical pin profiled tool was found to be completely free from any type of welding defects and had been observed as a successfully fabricated joint free from defects.

By experimental method, Wu et al.[6] investigated the influences of the bending speed, grain size and temperature on the springback of the wrought magnesium alloy AM30 tubes during NC bending.
Song et al. [10] numerically investigated the effects of the element type, element size and number of elements through wall thickness of tube on the springback of thick-walled high strength Ti-alloy tube NC bending.

For instance, the number of circuits required in wiring bundles is increasing due to the diversification of electronics.
This aging can reduce the composite performance by the metallurgical transformations which can occur: recrystallization, grain growth and/or formation of brittle intermetallic layers between both metals.
