The grain size distribution curve of the treated sludge, together with the other fillers, is shown in Fig. 1.
Neutralizing sludges have a number of hazardous properties, such as health hazards, ecotoxicity, release of hazardous substances into the environment.
The Keyence VHX-6000/950F digital microscope was used to monitor the adhesion of the polymer material to the concrete substrate and the method of distribution of individual grains in the matrix.
Samples are damaged at the weakest point of the sample, usually it's the place with higher number or pores.
Using a high-resolution digital optical microscope, it has been found out that the grain of hazardous waste is evenly dispersed and perfectly incorporated into the polymer matrix structure.

It can be seen that there is a large number of fibers with different morphologies in these composites.
There are a number of Y-junction fibers in these composites prepared with p-HA matrix.
The peak at 2θ =31.2o corresponding to D-HA (0210) crystal plane is selected to calculate its grain size in these composites.
Therefore, D-HA crystalline with the grain size of 41.2 nm is beneficial to the growth of multi-walled CNTs with the diameter of 40~60 nm in these composites.
The carbon fibers in these composites are formed by the catalysis of the aggregates of Fe-loaded MgO and P2O5 particles with large grain size.

The glass network, therefore, would become losser with increasing the number of NBO, and thus decreasing its viscosity.
From the Fig.2(a), it is observed that the pure sample sintered at 925˚C with little liquid phase, and the grain size of which is about 3μm.
Hence, the more α-SiO2 crystalline phase is presented, following with grain refinement.
The obvious evidence is that the 1.5 wt.% Na2O-doped CBS sample in the Fig.2(d) has more liquid phase, and the grain size of which is about 1μm.
While the number of non-bridging oxygens (NBO) in the glass structure will increase by increasing more Na2O content.

A large number of studies have confirmed, in the process of alloy solidification, grains can be refined, microstructure improved, and casting performance heightened by applying vibration[5].
The spatial mechanism freedom calculation equation is: (1) Where: m ― kinematic pairs number; n ― components number; v ― basic circuit number; fi ― freedom number of the ith kinematic pairs; ξj ― independent displacement equation number of the jth basic circuit.
F = 2 means freedom number of parallel mechanism is 2.

(4) By applying excitation to castings can obtain fine and density equiaxed grain structure.

Introduction Slip localization has been extensively observed in crystals and grains oriented for single slip.
At low temperature, the extrusion growth stops after a certain number of cycles.
That is why one computed cycle mimics a larger number of cycles, Nblock.
Fig. 5: a) Dependence of the predicted extrusion height after 30000 cycles with respect to PSB width and for various grain sizes, D.
The higher the grain size, the lower the required number of cycles to microcrack initiation, in agreement with experimental observations [24].

The nominal atomic compositions and sample numbers of the Mg-Zn-Y-Nd alloys are listed in Table 1.
Table 1 Nominal atomic compositions and sample numbers of the Mg-Zn-Y-Nd alloys.
As shown in Fig. 2, the grain size of α-Mg phase decreases with the addition of Nd till 1 at. %, and then increases with the addition of Nd.
It means that the grain size of α-Mg phase is the smallest in Mg96Zn2Y1Nd1 alloy.
The reason may be that the grain size of the C alloy is smaller than that of the B alloy.

Vol. 34 (1990), p.173 ] grain boundaries.
Insights into the effect of RE on grain boundary transport in oxides may be gained from recent studies on the effect of RE's on Al2O3 grain boundary structures.
Vol. 23 (2008), p.1494 ], RE is shown to segregate at Al grain boundary sites.
It is doubtful if the grain boundaries in thermally grown oxides were as simple.
Only a limited number of studies exist that compare the relative effectiveness of different reactive elements in different alloy systems, and results thus far are not conclusive.

Formation of martensite in fine-grained steels is probably the most common purpose in heat treatment of structural elements.
The prior austenite grain is divided into packets that consist of blocks.
In the images (Fig.2) the gradual elongation of grains can be seen.
After tempering the samples with higher nickel content at 600 °C the recrystallized ferrite grains are well distinguishable.
In molybdenum containing samples fine-grained microstructure developed.

The combination of Vortex type mixing chamber, SiC (grain size 60 microns and 120 microns) and nozzle material of stainless steel and the nozzles of diameters 1.83, 1.63 mm were used to find its characteristics.

The experiment shows that MRR is increased with increase in grain size and increase in nozzle diameter.
The experimental data show, Moreover, using small grain size of SiC abrasive (Mesh size 200) and higher air pressure would promote the material removal effects to obtain a larger MRR [13], [19].Based on the process parameters the Effect of abrasive flow rate, grain size, exit gas velocity, abrasive particle density, Mixing ratio, Nozzle pressure, Standoff distance, angle, Blasting time will be investigated [23] [3].
From this result we observed that as abrasive size is increased (grit number is increased) the MRR decreases.[10].A series graphical results has been drawn between the material removal rate and the pressure, abrasive material, SOD, mesh size, work piece, he proved that the material removal rate is directly proportional to the pressure and material removal rate varies with the abrasive particle size as the abrasive particle size increases material removal rate also increases[6].

The surfaces of the exited samples were sandpaper with the numbers of 100, 280 and 400.
This spectrum shows the ZnO grains with higher peak intensity which casused by more quantities of ZnO.
