They’re numbered as B25, B50, B75 and B100 ,according to the different lightweight aggregate replacement rates.
When the load is increased to 100kN, the diagonal crack appears, and the number of diagonal crack increase with the load.

The relation between material’s (scatterer) atomic number, scattering angle and the count rate are important for understanding the backscattering.
Such separations are not acceptable as significant number to detect particles for counting.
The particle/grain size nanocomposite were determined by the X-ray line broadening method using the Scherer equation (from the FWHM of the most intensive peak at () was found out to be about 12 nm.[3]: Scherer equation (1) Here D is the crystallite size in nanometers, is the wavelength of the radiation, is the peak width at half maximum intensity, k is a Scherer constant and θ is the peak position, is lattice strain.
Higher the atomic number scattering material, scatters greater proportion of particles which increases counting rate.
A simplified formula for the backscattering of mono-energetic electrons was given by Bethe et al. [4] I = (0.717 + cosθ) cosθ There is a connection between the atomic number (Z number) of an element and its ability to produce high backscatter count rates at the optimum distance between source/scatterer and scatterer/GM tube.If the scatterer was placed too close to the source/GM tube, no particles would the G-M tube from the scatterer and the scatterer is too far away from the source and G-M tube then the particles will be scattered by the air.

The roughness tester Surftest 301 enables measuring different parameters of tested surface roughness [1]: Rq – mean square deviation; Rm – maximum height of profile; Rz – height of profile unevenness measured in 10 points; Rp – maximum height of profile rises; mr – profile bearing curve (tp) [%]; DEPT – unevenness depth [%]; Pc – number of rises [1cm-1].
The following relation is used for mean value calculation [3]: xp= i=1nx1+x2+…+xnn (1) where: xp average measured value; xi measured value; i measurement number; n number of measurements.

In some cases, more often pull-out of grains of the friction material is obvious.
In case of ABS products, the surface layer of the braking pad after running-in and the mileage of 61 534 km demonstrated rough grains of abrasive material probably.

The results show that the martensite volume fraction increases significantly and diameter of grain size is increasing too (in Fig. 5).
The results show that the number of heating lines has a significant effect on the stress-strain curves, where the heating-lines number increasing results in stress amplitude increasing (in Fig. 7).
The results present that the k and n are increasing as the lines number is increasing.
The results show that the heating-lines number increasing results in the amplitude increasing of stress.
The hardening coefficient (k) and strain hardening exponent (n) increase as the lines number increases.

Introduction Nickel-based single crystal superalloys have been widely used as turbine blades for the good mechanical properties at high temperature. since there are no grain boundaries, the nickel-base single crystal superalloys eliminate the void-damages localized at grain boundaries.
A number of routines to import the ANSYS model data and results were implemented in MATLAB.

Integral grains have taken shape in the interfaces where there is not only ferrite but also pearlite.
Different numbers of interface inclusions can be found in the grains at rolling-bonding interface.

It was confirmed that the obtained Pb1-xMnxTe were single crystals in the cases of 0.002, 0.02, 0.2 and 2% Mn and low-angle grain boundary free crystals.
The sample with 10% Mn is a polycrystal, and the boundaries between three grains can clearly be seen in Fig.1 (d).

CARBIDE INSERTS GC1005 is a TiAlN PVD coated fine grain carbide with excellent hot hardness and toughness properties.
S05F is a fine grained carbide with a CVD coating, developed for finish machining.
Rake side, plate SNMG 12….16-QM- 1105 Conclusion Tool wear represent a complex technological facts, since several mechanisms are responsible, involving a large number of influence factors.

The high microhardness could be disadvantage as it is usually result of carbide forming at the grains or at the grains boundaries and they could initiate cracks forming.

Introduction Annually, the literature has reported a large number of works which highlights the synthesis of ceramic powders to manufacture membranes in seeking to fabricate such materials with higher homogeneity as regards the distribution and geometry of the pores contained therein.
It is noted based on micrographs, especially regarding the fracture area, the formation of neck and coalescence of grain, characterizing the sintering of the piece, as well as, the presence of visible spaces between the grains, allowing the selectivity of filtration.
