They were candidate tree with the number of 1, 2, 3, 4, 5 and 8 in table 2.

Cu based SMAs display great damping effect, sound absorption capacity, mechanical vibrations and mechanical waves because of the grain size, high quality, high forbearanceto corrosion, low preparing expenses and simple manufacturing [4].

The technique reveals crystal defects that cause strain in the material, including various defect clusters, inclusions and regions with mixed polytype or sub-grain structure.
SiC exists in a large number of polytypes, and it is crucial to maintain the desired polytype, 4H or 6H, during growth.
The wafers in a boule are numbered sequentially with #1 being at the seed end.
Compared to the status of two years ago, the above numbers reflect two-three fold reduction.

The obvious grains from proximal side to remote side indicate the direction of the force transferring, and the shear stress from axial force on this interface results in collapse.

However, in case of the occurrence of any failure, the mass production will automatically result in a great number of defective products.
Although the number of measurements is relatively small, we can conclude that the methods applied can give fairly identic7al results.
Since in case of specimens of grade EK the number of micro-voids are not decreased during firing, the surface effect clearly predominate.
The temperature during the enamel firing is significantly higher than the coiling and annealing temperature, therefore, both the partial dissolution and re-precipitation of some carbonitrides and grain coarsening of a ferrite can be expected.

This is due to the tendency of the “larger” particles to occupy the grain boundaries [5].
Stereo image showing topographical features of the F MMHC 15 minute worn surface with a number of fine slip bands (double pointed arrows) in different directions.
Under cyclic deformation, a large number of dislocations gets accumulated and form a series of closely spaced slip bands also known as persistent slip bands (PSB).
Nucleation of microcracks occurs preferentially on the PSBs and during a large number of cycles these microcracks coalesce to form macrocracks which leads to spalling of the material from the interface.

The grain size is around 80 µm and the crystallographic texture is less than 2.
Influence of strain rate on cyclic behavior and fatigue life The fatigue life, noted Nf, corresponds in this paper to the number of cycles necessary to observe a decrease of 25 % of the stress repsonse.
As illustrated Fig. 2, a low strain rate results into a higher cyclic stress and a displacement of the peak of tensile stress towards higher number of cycles.
In air, as shown Fig. 3.a, an increase in the cyclic stress, a displacement of the peak stress towards larger number of cycles and a reduction in fatigue life are observed at low strain rate, indicating a negative strain rate dependence of the stress response as in vacuum.

,sh) with s∈{1,…,m} for appropriate functions ψ, the time-discretized form of Eq. 9, utilizing the classical Euler implicit scheme, working with the uniform decomposition of I to a finite integer number m of sub-intervals of the same length h=τ/m, reads a(v,D2ums)+b(v,ums)+c(v,ums)=Fms(v) ∀ v∈V (10) where D2ums=h-2(ums-2um s-1+um s-2)∈W, Fms(v) means F(v) with fi and gi replaced by fims and gims and s (here and later) is an arbitrary index from {1,…,m}.
Thanks to the quasi-linearity of Eq. 9, for a large class of domains Ω, as from those consisting of a finite number of particular grains, without any cracks inside, it is possible to derive u in Eq. 9 from the limits of the sequences of Rothe, constructed from Eq. 10.
Simple identification problems (with a small number of constants, identified from static tests, microscopic observation and numerical calibration) are handled applying the least squares or the conjugate gradient approaches in [3, 15] where selected computational applications to a) structural alloys, b) an intermetallic alloy TiAl, c) long fibre composites and d) special ceramics (as silicone nitride) are documented, too.
