In order to ensure the safety of high strength steel components, it is necessary to conduct further studies on the fatigue behavior and fatigue mechanisms of high strength steels at the numbers of cycles from 108 to 1012.
They show that fatigue failures take place at the numbers of cycles above 107 even 109, which means traditional fatigue limit does not exist.
The shape of S-N curve could be affected by specimen shape, loading characteristics, inclusion size and number of samples.
They show that the area of ODA and number of cycles are related to hydrogen content.
In the interior, a strain concentration will somewhere exist between grains at a location where: (i) a small inclusion or precipitate is lodged between two or three large grains; (ii) long grain boundary; (iii) a combination of (i) and (ii).In interior strain concentration zone, it is possible for a very short Stage Ⅰ- and then a Stage Ⅱ-oriented type of crack to initiate and propagate.

Sn and Bi grains with purities of 99.999 at% (Kojundo Chemical Laboratory Co., Ltd.) were weighed for each standard sample.
Sn and Bi grains with a purity of 99.999 at% (Kojundo Chemical Laboratory Co., Ltd.) were used to prepare a diffusion couple.
The nominal c0 value was set to 10 at% by adjusting the weights of the Sn and Bi grains.
The number of measurement points was set as two in order to determine the two unknown parameters corresponding to the diffusion coefficient and initial concentration at the measurement point immediately after complete melting.

We then have a number of consequential relations between the phenomenological coefficients such as: LiA + LiA' = LiB + LiB' , (3) - oxygen ion -A, A' cations -B, B' cations 1 Ar r2 Ar r 1 Or r 2 Or r Br r where i = A, A', B, B', O.
In Figure 4 we present results of Monte Carlo simulations for the ratios of the tracer diffusivities for a number of combinations of exchange frequencies.
We consider open system conditions where the system consists of fine grains with enough short circuits for the vacancies everywhere to very quickly establish equilibrium according to the external oxygen partial pressure [11].
If this mechanism is the main diffusion mechanism for bulk diffusion then obviously there will not be any demixing effect in the bulk: at least no detectable movements, but it is still possible to have some atomic segregation at opposite sides of grains.
On the other hand, if only one cation vacancy is involved in the cluster mechanism then there will not be any tendency for demixing inside the grains.

Introduction There are many rural settlements across the country, large area,great number,significant differences in the natural environment and development degree.
It is the old industrial base and the major grain-producing areas of China, and it is the Chinese major timber and mineral production base as well.
According to the statistics shows that the number of countryside and Natural Tun of Harbin and Qiqihar is far more than the number of Daqing.
Type Analysis Of Rural Settlements Development Of Hadaqi Region By categorizing the basic information，we can broadly understand the the basic development of Hadaqi region: such as the great disparity of  rural settlement development  level ;towns and villages are in large numbers of small scale, and they are uneven distributed; bourg appearance lacks of features and vitality.

Experimental results showed that the Vickers microhardness number have been increased to 66 by addition of 15% ZnO, which was double that of the matrix material.
Vickers microhardness number Composite (wt %) Hardness (VHN) AA7068 33 AA7068 + 5% ZnO 44 AA7068 + 10% ZnO 50 AA7068 + 15 % ZnO 66 Table 1 demonstrates the Vickers microhardness number of AA7068/ZnO composites.
The increased wear resistance and reduced volume loss can be attributed to the addition of hard ceramic particles, homogeneous distribution, grain size and sintering parameters [6].
Few large number of deep and shallow narrow plastic grooves were present paralleling to the sliding direction which is due to intensive material removal which is the characteristic of abrasive wear [5,12,17].

Introduction Dissimilar to thermal spraying processes, the working temperature of gas dynamics in kinetic spraying is too low to cause thermally activated processes such as melting, solid-state phase transformation, grain growth, and high temperature oxidation [1].

Text can be decomposed into a number of featured items to express, generally included in the basic text language units (words, phrases, words or phrases) which indicate that the text D can be expressed as D=D(t1, t2… tn), Where t1, t2…. tn represent each feature items;3.

Traditional and TF-IDF formula, TF value tfjk means the Statistics Number which feature items tj appears in the document dk.
If this number was given different coefficients depending on the location, the feature items for different importance in different locations can also be reflected.
Therefore, the position of the previously described nine coefficients were given: λ1, λ2......... λ9.Then the number of times each statistical feature items that appear in different locations:tf1 , tf2,.......tf9.

However, when a jump is attempted, there will be a certain number of atoms forming a ring to obstruct the jump.
But this can be a reasonable approximation because the XRD measurements on nano ZnO reveals zincblende structure where lattice parameters and grain size are found out.
After the evaluation of phonons from the modified rigid ion model, both the real and imaginary parts of the Green’s function G and F are worked out from the computed phonons as (3) (4) where n is number of atoms in unit cell, α and β are the degrees of freedom, is the wave vector, l the unit cell and e the eigen displacement.
Diffusivity The attempt frequencies for various isotopes are computed at different temperatures and the corresponding diffusion coefficient for the self- diffusion of anions and cations in ZnO are evaluated by using, (8) can be estimated using the relation, (9) where H is Haven’s ratio, d is the jump distance, n represents number of identical jumps.
This is in concurrence with the experimental result observed by Nogueira et al. [3] for ZnO polycrystalline ceramics with grain size (20 nm) at 1279 K where it is 5.34X10-14 cm2/s.

These curves were obtained first by estimating the fatigue resistance (50 % level of probability of survival) with Staircase method (15 tests with a 10 MPa step and 10 7 cycles as reference number of cycles).
So the possible occurrence of secondary effect such as grain growth changes in precipitate distributions and changes in segregation pattern can be prevented.
This table also shows N and K, where N is the number of cycles correspondent to the intersection between the straight line and an hypothetic for Al alloys fatigue limit; or using a better definition the fatigue strength here established at 10 7 cycles.
Such properties include the local fluctuations of the composition; the different size and orientations of grain; the distribution and sizes of slag inclusions and of segregations; cavities, blisters, blow holes and microstructural defects in general.
In particular this study dealt with axial high cycles number fatigue tests performed on a servo-hydraulic machine and it has shown that the casting process and the liquid hot isostatic pressing (LHIP) exert high influence on the fatigue strength properties, in particular the presence of defects, especially shrinkage cavities, contributes to decrease the fatigue strength, because they aid fracture initiation and propagation.
