However, there were a limited number of reports which deal with the field emission characteristics of the sphere-like diamond microcrystalline aggregates, which were grown in the high methane concentration (H2/CH4=100/10SCCM) using a microwave plasma CVD system in our laboratory.
The peak at 1332 cm-1 , which is located on the top of broad D-band, is due to diamond grains Raman scattering .
D-band and G-band are due to the existence of sp2 carbon phase in the grain boundaries and the surface between the sphere-like diamond aggregates [8].
Aggregates exhibiting good electron field emission would be attributed to three possible mechanisms. (1) there are TiC layer between Ti substrate and the sphere-like diamond microcrystalline aggregates film according to the XRD result, so the ohmic contact appear and reduce the contact barrier[9][10]. (2) The sphere-like diamond microcrystalline aggregate has small crystallite size, which corresponds to high grain boundary density, which is served as electron channels from substrate to surface.
The good emission properties of the diamond aggregates are considered to be combined results from the lots of the grain boundaries in the diamonds microcrystalline aggregates.

Since the recent material models usually possess many parameters and require cumbersome experiments, a reliable numerical material testing would be helpful to reduce the number of experiments.
Nowadays, anisotropic yield criterion becomes more complex and requires a large number of anisotropic parameters that are determined by some material tests.
This oriented texture is formed by the integration of crystal orientation rotation of each grain.
Numerical Tensile Test First, to decide the appropriate number of elements, numerical tensile tests in the same material parameters were conducted, and standard deviations were obtained, shown in Table 3.
Number of elements 32 72 128 200 Strain-rate dependent method 10.01 8.22 3.21 2.38 Successive integration method 11.25 7.11 3.51 1.43 By this preliminary analysis, 128 was selected as the number of elements in the simulation.

Only additives which form a refractory grain boundary phase, e.g.
The grain boundary phase is the residue of a liquid phase formed upon sintering by reactions between Yb2O3, Si3N4 and SiO2.
Such reactions also promote growth of elongated grains of β-Si3N4 from supersaturated solutions of α-Si3N4 and the additive phase.
In order to reduce the number of parameters affecting the final composition of the ceramic, fully reacted Yb2SiO5 is used as sintering additive.
The grain size fraction below 32 µm was chosen for use as sintering additive.

. – the fraction of 0.125 mm grain size cannot be found among the additives, therefore the fraction of 0.25 mm grain size should be considered, as fine particle.
Thus the content of the fine particle can be determined by summarizing the amount of the various additive grains being smaller than 0.25 mm, i.e. the amount of cement and the lime-flour.
The original recipe (refers to 1 m3 of concrete) Total amount of additive, admixture and auxiliary materials 1820 kg Amount of fraction with grain size less than 0.25 mm 18 kg Cement 255 kg Lime fume 0 kg Total fine particle content (fraction with grain size 0.25mm + cement + complementary materials) 273 kg Admixture (Plasticiser SIKA BV-40) 1.53 kg Potential solutions One of the possible solutions is to modify the recipe of the certain grade of concrete to assure the pulp saturation of the concrete in order to provide pumpability, without altering the structural additives.
Their application brings about increase of the consistency, strength and density of concrete, furthermore the adhesive force among the grains increases in spite the reduced water content.
This letter is followed by two numbers.

For example, Esteban et al. [23] found that the grain size and the WC reinforcement particles both had a major effect on abrasive wear of Ni-base alloy coatings both with and without WC reinforcement, followed by reinforcement.
The volumetric rate obviously increases as grain size increases from 20 µm to 180 µm since the penetration ability of abrasive increases with increasing the abrasive size [1, 16].
Effects, however, are much lower compared to those of abrasive grain size and hardness.
Furthermore, it is observed that the wear rate is maximal for the trial 9 due to using the highest level of abrasive grain size (180 µm), the lowest hardness (44.2 HRB), second level of sliding distance (60 m) and highest level of applied load (40 N).
The last study showed that abrasive grain size exerted the greatest effect on the abrasive wear, but it was followed by hardness [21], which supported the previous work.

Although a considerable number of studies have been focused on the mechanisms of emerging and spreading of stress corrosion cracking (SCC), the underlying mechanisms governing these phenomena continue to be debated.
However, information about the constituents cannot be obtained directly: passivation layer or variation of the grain orientation
The pad size and the array distance were chosen by taking into account the grain size distribution in the working area.
This implies that the measurements dependent on the pad length but not on the grain size (see Fig. 2).
The grain size of the specimen ranges from 30 to 150 µm.

Presented example of the measurement area was 10 × 10 and 1.2 × 1.2 for the observation of burnished material grains while maintaining resolution of 256 × 256 points.
Steel C45, has a ferrite-pearlite structure, there is a very clear orientation, deformation and fragmentation of grains after burnishing.
Pearlite and ferrite grains are flattened and create in the area of asperity arches that reach even deeper into the material core.
The fragmentation of grains is also visible in the areas between asperities.
The depth of plastic deformation and the direction of maximum elongation of grains (for the material with plastic properties), significantly depend on the type of previous treatment.

is a random number distributed uniformly[0,1]. is another uniformly-distributed random number on [0,1] and is a parameter of QPSO that is called Contraction-Expansion Coefficient.
Unless the numbers of samples is small, it is difficult to search n samples’ separation-degree.
In addition to the analysis of some hardenability was significantly larger or significantly smaller furnace No. statistics, and some of the many chemical components simultaneously near the upper or lower oven number also excluded analysis.
This is consistent with the conditions of a total of 52 heat number.
Because of its continuous casting to produce a timber of fire bars 20CrMnTi grain size generally between 5-7 stage, therefore, the impact of grain size of the formula does not consider the hardenability.

The integrity of structures and machine components is highly dependent on fatigue properties, as, for instance, a large number of turbine engine failures are associated with high-cycle fatigue [2].
Though it is vital to study the notch effect in fatigue, the number of studies for the effect of small notches in titanium alloy is rather limited.
Because of this smaller volume, there is smaller chance to encounter the grains whose orientation is favorable for slip.
Consequently, there would be a limited number of grains that can activate the crack initiation around the notch root.
