A contact surface between two grains (grain boundary) makes a crack initiation site in case of reduced grain boundary cohesion.
Cracking begins by forming an even fracture facet; in so doing, no signs of multiple slip at a different angle are visible in the same grain.
Such a pattern is typical for aluminum-based [7] and titanium-based [8] alloys, as well as for a number of superalloys [9].
Residual stresses, being of the state of three-dimensional compression at the peak applied load, assist local plastic instability in a favorably oriented grain.
Remarkably, many of those fine grains (granules) look spherical particles.

RA 700 W denoted by the material number 1.0950 is also well known as S495MC*.
Retained austenite grains (< 1 mm) are observed partially inside the ferrite grains.
In addition to this, a number of very small particles, most probably carbides, within single laths can be observed (marked by arrows).
While these plates nucleate at austenitic grain boundaries, there is also much nucleation within the grains, i.e. intra-granular nucleation, and secondary plates from primary plates remote from the grain boundaries [50].
The bainite grain is divided into sub-grains between polygonal ferrite grains.

Particularly for larger number of passes the ECAP texture can be explained in terms of standard rolling or extrusion textures.
In the as-cast condition a random distribution of comparatively large grains was found for both materials.
In the case of random grain orientation, e.g. in ingot material, the starting sample orientation has no influence on the texture development.
The increase of the texture sharpness after each pass may result from grain rotation.
As in routes A and C, the effective shear angle decreases with the number of passes.

The number of applications of wood in building structures increases in recent years.
The histogram of RM quantities for the whole number of 80 measurements.
The wood density and the tensile strength parallel to grain were further determined on the sampled wooden material by laboratory procedures.
Samples, for which the density was determined, were consequently loaded under pressure in the direction of grains in the laboratory testing equipment.
The evaluation of tensile strength of wood under pressure in the direction of grains.

Larger crystallite size yields reduced grain-boundary effects.
The Sr substitutions yield larger grain size.
The differences in grain size between the parent compound and the doped samples were mainly due to the presence of strontium which influences the grain growth.
The grains become densely packed.
When Sr2+ is substituted in place of Ca2+, result in release of more number of electrons.

In recent years, the number of storeys of buildings and structures under construction has significantly increased.
Analysis of Publications American scientists have come to the conclusion that the use of fiber-reinforced concrete will simplify the construction of buildings and reduce the number of structural damage after an earthquake.

The composition of iron sands, purity degree, hematite mineral grain size, and space group were analyzed by XRF, XRD, FTIR and SEM.
After the varied calcination process well done, the samples were characterized by SEM (Scanning Electron Microscopy) to determine the grain size distribution, homogeneity, and morphology.
Measurement of XRD (X-Ray Diffractometer) Rigaku MiniFlex II with PDXL2 software to know the crystal structure, compound phase, and grain size or crystals size was analyzed using by Deybe Scherrer equation.
The crystal structure of NPH500, NPH600 and NPH700 is rhombohedraly with hexagonal R3C gruop space (167) [39] where the hematite phase is according to the ICDD DB card number 01-089-0597, 01-077 -9924, and 01-079-0007 respectively.
Based on the SEM image, it can be seen that α-Fe2O3 particulates appear to agglomerate and the particulate lumps begin separated when the calcination temperature increases where the grain size distribution is not uniform.

Typical components which including ludous and sandous were observed with splitting perpendicular- to-wood-grain under rare-met earthquake excitations, but other structural members were not found noticeable damage.
Nowadays there are still a great number of traditional timber buildings preserved in China and neighboring countries.
Under the rare-met level of 7 degree excitations, the ludous (cap blocks) and sandous (distribution blocks) of the dougongs in the first story were found perpendicular-to-wood-grain splitting.
It was found that the ludous and sandous took place splitting perpendicular-to-wood-grain under rare-met earthquake excitations.

Apart from identifying relationships between process parameters and surface finish through graphical presentations, a number of techniques (Full Factorial Design, Response Surface Methodology: RSM and MATLAB) have been applied on the experimental data to arrive at some conclusive remarks.
Grinding is a major machining operation with a number of interactive process parameters.
Anne Venu Gopal [5] conducted experiments to study the effect of wheel parameters: grain size and grain density and grinding parameters: depth of cut and feed on surface roughness and surface damage.
Twenty seven numbers of samples are used.

But it finds that we can’t estimate the power consumption which based on the fine-grained voltage scaling techniques in paper [2].
In one hand, paper [7] pointed out that it needs a more complicated hardware system and produce a large number of interrupts.
A chip is always composed by a large number of CMOS transistors.
The dynamic energy Wd of the system would be: Wd= Pddt≈K'×f3dt (4) We assume that is the total number of clock for a task set, then the finish time of the task set would be: t= sf (5) For a task as shown in below, S represents the total number of clock for the task, F represents the clock frequency, T is the finish time of the task.
The reason why we use the coarse-grained update interval rather than fine-grained is that it simplifies calculation complexity in the algorithm and reduces the frequency of the update of the interval. 2) Not like the most of papers, we consider the DVFS overhead carefully referring to the latest works.
