It is worth noting that once a good dispersion of the particles is achieved, mechanical properties can be improved by reducing the grain size of the matrix and by work hardening.
It could be interpreted by considering that there could be a number of particles which do not effectively contribute to strengthening of the material.
Possible explanations are that these might be placed in correspondence of grain boundaries or might form small aggregates of few particles which are not as effective as the discrete ones.
Probably. this is due to the fact that these are placed at grain boundaries and some others form small clusters not effective as the discrete particles.

Nevertheless, the main disadvantage of the sputtering technique is it produced much larger grain size film compared to the other deposition technique, which in this case is unfavourable [10].
It has been studied that due to the larger grain size obtained by the ZnO nanoparticles deposited by spin coater, the sensitivity of the substrate also reduced and not enough crystalline to acquired high capacitance value at low frequency measurement [18].
The small grain size obtained due to its deposition infirmity will be improved by annealing process and further studied in this research.

The addition of Mn will segregation on the austenite grain boundary and suppress nucleation, which eases the requirement for cooling speed to some extent.
The higher cooling speed, the more martensite and finer grains[10].
Roller hearth furnace is a furnace that consists a number of parallel rollers.
When the forming temperature is too high, the austenitization degree is excessive resulting in the austenite grain coarsening.

(GB/T 5512-2008 Inspection of grain and oils, determination of crude fat content in the food). 2.3.2 Determination of lipase activity Definition of lipase activity: 1g solid enzyme powder hydrolyzing fat to produce 1μmol fatty acid in 1min was a unit of enzyme activity at 40℃ and pH 7.5, indicated with U/g.
Reaction formula as follow： RCOOH + NaOH → RCOONa十H2O Determination method：Referring to the national standard of China (GB/T 5512-2008 inspection of grain and oils, lipase activity determination of grain and oils). 2.3.3 Biogas rate and biogas yield Biogas rate and biogas yield was tested by drainage gas-collecting method.
After sub-peak period, with a large number of substrate consumed, biogas production and enzyme activity both decreased rapidly until biogas production termination.

A large number of these operations in the manufacturing processes force suppliers to reduce costs and increase productivity while maintaining the required accuracy and quality of the preforms or of the finished products.
An abrasive with a grain size of 150 – 300 μm was used.
The grain direction in the material was not taken into account when cutting the specimen.
This resulted in the formation of cracks and their further spread along the grain boundaries.

Designation: 1-6 - numbering of samples Result and Discussion The results of measurements of the conditional yield strength are shown in Fig.2, there is also shown the nature of the change in the hydrogen content along the cross-sectional thickness of reinforced concrete structures.
Studies of the structure of grain boundaries and areas around micro-ulcers have shown the content of corrosive agents in the working environment with which the reinforcement of reinforced concrete structures, which leads to loosening and weakening of the bonds between the grains and, consequently, to reduce crack resistance.
However, they can originate and develop in the body of grains.

An unsuitable chemical composition (increased content of reactive lime and sulphur) is a characteristic of this type of energy by-product, as is the need to significantly increase the value of the water coefficient when used in cement composites that are affected by grain morphology.
The same grain size curve was designed for all formulations to avoid the influence of mechanical parameters due to the different compositions of the aggregate mixture.
The increased amount of these two input components will be due to the high water content of the fluidised fly ash, which is closely related to the unsuitable morphology of these grains.
Without using this agent, an air gap would have existed between the probe and the sample that would have caused a reflection of the ultrasonic waves, and a small number of pulses would have passed through.

c) The values of k agree very well with numbers obtained from resistance measurements [11] in similar samples under similar conditions.
The role of grain boundaries and short circuits [2,25,27] cannot be neglected for the interpretation of the results obtained form thin film reactions and unfortunately, there are no data for tracer grain boundary diffusion of Si in Co and of Si and Co in CoSi published.
Thus it would be desirable to have reliable data on the diffusivities, for example from direct diffusion measurements in thin film geometries with similar grain size and morphology.

Also, an old and new city demolition waste passing sieve number 4 has been mixed with expansive soil to reduce its swelling potential.
Results and Discussion Abrasion test by Los Angeles device are conducted to evaluate grain size distribution, compaction (modified proctor) and unconfined compressive strength.

SFMO has a high Curie temperature of 420 K [1], a high low-field magnetic resistance (MR) associated with grain boundary tunnelling [2], and an about entire spin polarization [3].
Simultaneously, the number of reacting species was increased.
Fe atom precipitation on grain boundaries was unlikely to occur in this case, because the increase of oxygen pressure during annealing should result in an increase of the amount of precipitated Fe atoms and, correspondingly, in an increase of the magnetic moment of the high-temperature magnetic phase with Тс = 700 К. 100 200 300 400 500 600 700 800 0 1 2 3 4 M (µB/formula unit) T,K B=0.86T 1 2 0 2 4 6 8 -35 -30 -25 -20 -15 -10 -5 0 1 MR, % B, T 2 Fig. 5.
Conclusions The presented work has shown that Sr2FeMoO6±δ synthesis using partially reduced precursors of SrFeO3-х and SrMoO4-у comprising nanometer-sized grains, resulted in single phase Sr2FeMoO6±δ with superstructure ordering of Fe 3+ and Mo5+ cations.
