These composites show good quality properties like reduced density, controlled thermal expansion coefficient, improved damping capabilities and good shielding to nuclear radiations.
ANOVA is performed to find the significant contribution of each input factors on the output response.
The uniform dispersion is witnessed through the optical microscopic image (Fig. 1) and the mechanical property of the composite is studied as per ASTM B557M–10 (Table 1).
The selected factors and levels are listed in Table 2.
ANOVA is mainly performed to identify the impact of individual factors on the process results [10].

Indeed, the chip formation is due to a combination of two thermomechanical factors.
This factor depends both on the interface adhesion properties and on the substrate/coating thermal expansion coefficients.
This factor is enhanced in polyamide coatings having a low mechanical strength and a high thermal resistivity.
Taking into account these conclusions, the substrate thermal properties must have an influence on the coating removal efficiency.
The comparative study of different substrate highlighted the influence of the substrate thermal properties.

This paper lists the results of a series of tests on samples, made of VC, SCC of equal strength, and SCC with identical w/c factor.
Subsequently, a comparison of the mechanical characteristics is made, revealing important differences regarding several fracture parameters.
Introduction Extensive research has been carried out on fresh, hardened and transport properties, as well as on durability aspects [1-3] of SCC, showing that the substantially different composition, opposed to VC, sometimes causes an altered mechanical behaviour.
Influencing factors for these differences are: a dissimilar specimen size, shape and self-weight, diverse FPZ length, varying stress states near the crack, and potential storage of elastic energy during testing.

Cubic boron nitride (cBN) is a excellent super hard materials with superior mechanical properties that has been widely used in different industrial applications.
Conventional cBN was sintered with binder in the cBN powder, and the binder affect the mechanical properties of cBN.
Introduction Cubic boron nitride(cBN) is excellent super hard materials which possess superior properties[1-3].
Thus, these binders affect the mechanical and thermal properties of cBN samples.
The binder is one factor to affect the properties of cBN samples.

As addition of SiC, the intragranular and intergranular location of the reinforcement nanophase improves the physical properties by affecting the local tensile and compressive stresses at the boundary between the two phases.
This specimen has maximum mechanical properties such as hardness, fracture toughness and strength.
Mechanical properties of Al2O3/5 vol.% SiC.
For coarse grain size specimens, fracture mode of transgranular type was not affected to large grain size because of toughening factors such as crack deflection and crack bridging could not be occurred.
As the sintering temperature increased, mechanical and wear properties were decreased.

Using the dynamic thermal analysis equipment, Melo and Radford [6] predicted the visco-elastic properties of the transversely isotropic laminates for the different temperature and frequency ranges and described that the storage moduli were decreased with an increase in the loss factors under the effect of temperatures.
In order to determine the natural frequencies and loss factors under different temperatures, the impulse technique can be utilized.
Hence the properties like the loss factor, natural frequency, storage modulus of glass fiber do not get changed during the above temperature range.
It is due to the lower in plane properties of the FRP skins at this orientation.

Microstructure and mechanical properties affecting crack growth behaviour in AA6060 produced by equal-channel angular extrusion L.W.
Tab. 1 Tensile properties, coefficients for Paris-Erdogan (Eq. 1) and fatigue crack threshold, R=0.1.
These findings point out clearly the dependence of crack growth properties on grain size and grain size distribution.
Charpy impact tests To characterize the material's fracture properties under impact conditions, instrumented Charpy impact tests have been performed, Figure 6.
This implies that the improved ductility and strain hardening capability of the optimized condition also had a positive effect on its crack propagation properties.

The welding properties of nodular cast iron are mainly influenced by the carbon content.
The number, dimension and distribution of the graphite nodules, the chemical composition of the matrix (i.e. the Si content) and the morphology of the structural phases are additional factors that could influence the mechanical properties.
The heat and the relatively high cooling speed generated during welding [8] could favor the formation of fragile phases (such as cementite), thus affecting the static and dynamic as well as the machining properties.
The ultimate tensile strength of 380...405 N/mm2 represents only 86...91 % of the cast iron strength and the variation of the friction welding parameters dis not lead to any significant improvements of the mechanical properties
In addition, the austenitization temperature can be reached, thus leading to carbon dissolution and the generation of a carburized layer on a narrow in the low alloyed steel It was observed that the deformation of the graphite nodules during the welding process leads to a reduction of the bearing section of the welded structure, thus leading to a reduction of the mechanical properties.
