The parameters related to traffic characteristics included the number of light-duty vehicles per hour (LV), the number of heavy-duty vehicles per hour (HV), the total number of vehicles per hour (TV) and traffic coefficient (TC, representing the degree of traffic congestions).
This means that road texture depth and the number of heavy-duty vehicles play a more important role in influencing particle size composition than traffic coefficient, the number of light-duty vehicles and the total number of vehicles.
Fig. 1 PCA biplot for identifying predictor parameters (LV=the number of light-duty vehicles per hour; HV= the number of heavy-duty vehicles per hour; TV=the total number of vehicles per hour; TC=traffic coefficient and RTD=road texture depth) Development of prediction models.

The experimental results show that: after quenching hardness value no significant change; But after annealing the hardness value decreased and after annealing the crystal grain of the underlying tissues uniformization become tiny.
We also know that the past ten years, China's production and research of wear parts is very active, progress is obvious to all, China's annual production and consumption wear parts a huge number, if we can basically make these wear parts have good use, its benefits will be very significant.

Test samples of RCA have always different source, grain composition and other physical and mechanical properties, which are variously described in each different paper.
Type of MSC is closely related to amount of fine particles, water absorption and shape index of grains.
The smaller number of gained points for crucial factors is, the more suitable RCA is.

A number of oxides, carbides and nitrides were used as second phase particles to produce electroplated or electroless composite coatings.
Improvement of the properties of the coating can be achieved by refining the grain size of the deposit.
Each experiment was carried out using a plating bath that contains nickel sulphate hexahydrate as the source of nickel, ferrous sulphate heptahydrate as the source of iron, nickel chloride hexahydrate as complexing agent, boric acid as buffer, and sodium saccharine as grain refinement agent.
The presence of the Si3N4 particles in the nickel-iron nanocomposite coating increases the number of boundaries between particles in the matrix.

It can be seen that the alloy exhibits equiaxed grains. 300μm Fig. 1 Microstructure of cast c919 Hot compression tests were performed to investigate the hot deformation behavior of the material.
Work hardening are usually caused by large number of pinned dislocations resulted from increasing dislocations density under external force.
It clearly shows that the new equiaxed DRX grains could be found at a strain rate of 0.01s-1, while it can’t be found at a strain rate of 1s-1.

During almost twenty years after the publication of the first paper on low dimensional or nano-structured thermoelectric materials [1], the number of papers published on these materials has been, greatly, expanded.
This is surprising result, may be due to two mechanisms that counter-balance each other: one the (expected) increase of the grain size with temperature, and another, as a result of breaking of Mg–Si bonds.
Galkin et al [20], have shown that for annealing temperatures 650–700ºC the number of Mg2Si crystallites decreases partly as a result of breaking of Mg–Si bonds.
In the Bruggeman approximation, which applies to the aggregate structures, where the phase grains are interdispersed and topologically equivalent, the effective dielectric constant, εBR, is given by [22] (4) where εj is the dielectric function of the j-th phase with volume fraction fj.

This choice, though different to the real conditions, in which the mechanical press operates simultaneously on a progressive die, with a number of workpieces at a different stage of the process, give more lightness to the calculation and does not change the real conditions of the process thanks to the superposition principle.
Results of these measurements, summarized in Fig. 9b), showed that it is possible to consider constant the value of HV through the thickness; in Fig. 9c) it is shown a 100x photo of the rotor to observe the grain internal distribution.

Knowing by the designer the geometrical and electrical specifics for the final rotorit was possible to set a minimum number of steps to complete the product.

They accounted for the observed difference in the PLC effect intensity in terms of anisotropy of the microstructure or the morphology of the grains.
Elongated grains can be seen in the optical microstructure.
Similarly, the yield stress or flow stress of a polycrystalline may be calculated by avgc i i c Mm n τ τ σ = = ∑ (1) where σ, cτ , n, and im are the flow stress, the critical resolved shear stress, the total number of active slip systems, and the reciprocal of the Schmid factor on the ith slip system, respectively.
If a sufficient number of precipitates are not sheared, the serration cannot be detected.

It was attributed to the change in the microstructures of the substrate in the crystalline specimen during CVD processing at 900�, i. e, coarsening of grains.
The crystalline specimen did not show a knee and it failed at a finite number of cycles up to the fatigue limit corresponding to 107cycles (370 MPa) unlike in the case of the amorphous specimen with a knee at 395 MPa.
After the fatigue test at the stress amplitude of the fatigue limit, no cracks in the amorphous and crystalline specimens were on the coating film, and only a few number of cracks were observed in the ion-plated specimen.
However, it has the lowest fatigue strength in the long life region because the grains in the substrate had coarsened during the coating process at 900℃.

A significant number of intermetallic Heusler alloys (HA) of X2YZ formula, where X and Y are transition metals, and Z is an s-p element, and of a crystalline structure of L21 have been predicted theoretically to be half-metals due to an energy gap at EF in the minority-spin subbands [1].
The Ni2MnIn alloy films deposited at 730 K show a well-ordered single-phase L21 structure with a small tetragonal distortion, a = 0.6185 nm and c = 0.6076 nm, and a rather great mean grain size of about 80 - 90 nm.
However, the main diffraction lines become wider, and additional diffraction lines, marked by number 2 - 4 [2 - (321), 3 - (410) or (223) and 4 - (141) or (303), and line 1 is not identified] emerge (see Fig. 1), indicating formation of a structure with the B2-type ordering.
This is also accompanied by a noticeable reduction in the mean grain size.
