Results show
that strain rate has some effect on the mechanical properties and deformation stability of the alloys.
It is well known that the deformation properties and mechanical behavior of Al-Mg alloys are sensitive to strain rate [1].
Therefore it would be expected that strain rate together with variations in mechanical properties of these alloys would change their failure mechanism.
These results indicate that strain rate has a considerable effect on mechanical properties of these alloys.
It is reported that localization happens due to interaction between different factors such as material hardening or softening, geometry and loading situation [4, 15].

In order to solve this problem, a high accuracy grinding method using a large cup wheel had been proposed and the tilt angle of the cup wheel spindle become a crucial factor affecting the ground form errors.
The seal rings are often made of hard materials such as silicon nitride, alumina, silicon carbide and tungsten carbide for their excellent mechanical, thermal properties and chemical stability, and the form error is restricted within the length of one to two helium light band [4, 5].

Usually, experimental work is a common way to find out the optimum deposition conditions and correlate between the thin film properties and the deposition parameters.
The sputtering deposition process aims to produce a high-quality coated film with desirable optical, thermal, chemical, mechanical, electric and magnetic properties referring to required film properties.
In this context, the thin film properties such as crystallization and preferential orientation are constructed based on various deposition conditions [5].

Used the influence of technological factors of the rolling process on the intensity of the rolling out of the defect to determine the value of deformation and the coefficient of use of the plasticity resource.
Quality of sheets and strips determines by the accuracy of their size and shape, chemical composition and physic-mechanical properties of steel, surface quality [1].
The surface of hot rolled and cold rolled strips and sheets for one reason or another often affected by defects.
In this regard, it is important to identify the factors influencing on the formation of such defects [3].
To determine the value of deformation and the coefficient of the plasticity resource at the stage of transformation of the surface defect use the influence of technological process factors on the intensity of the rolling out of the defect.

Hence, it has been suspected as a
factor affecting behavior of the blends.
Mechanical Testing.
Different fracture behaviors exhibited by the weld lines might be because of significant difference in properties of the weld line in each of the blends.
Mechanical properties of each of the blends obtained from uniaxial tension test were used in the analysis as listed in Table 1

Additionally, samples were evaluated using dynamic mechanical analysis, and the results suggest that the obtained MMC could have very good mechanical properties, similar or superior to the aluminium alloys commonly used for structural applications such as 6XXX family.
Just like the kind, size, shape and quantity of reinforcing particles affect the properties of a MMC, also the fabrication technique has a considerable influence.
A very interesting process is the semisolid technique; highlighting the work of Du et al [7] who used thixoforming in a semisolid state for produce Al-MMC reinforced with high alumina contents, obtaining excellent mechanical properties.
The study has relation with some phases formed in the material during the fabrication process and the transformation of this phases during heat treatment, the distribution of the reinforcement (slag) and some guiding about the mechanical properties determined by means of dynamic mechanical analysis (DMA).
The generation of intermetallic phases normally considered harmful for mechanical properties are easily modified by means an adequate heat treatment, transforming partially the metastable phase Al6(Fe, Mn).

Very significant feature of spinning is ability to produce components with high mechanical properties and smooth surface finish.
Although knowledge about mechanics of spinning, which helps to understand final properties of spun parts, have been developed by systematic investigation of the process using both experimental and theoretical techniques, several gaps still exist in the prediction of the product properties.
Basic mechanical properties and facilities defining material plasticity (ultimate tensile strength (Rm), 0,2% offset yield strength (Rp0,2), elongation (A5), medium value of normal anisotropy (rs), planar anisotropy (D r) and strain-hardening coefficient (n)) shows Table 1.
With this design not only all main effects of the factors are estimable, but also all important two-way interactions between the parameters.
In order to assure the statistical properties the runs were made in randomised order.

The magnitude of the cutting forces is influenced by the structure and mechanical properties of the material being machined, the geometry of the cutting tools, the cutting parameters used, and the cutting conditions.
Akif Erden observed changes in properties by adding molybdenum to powdered steel [6].
Analysis of the obtain results showed that cutting edge geometry, cutting speed and feed rate were the most significant factors for the resulting cutting force, while cutting edge geometry and feed rate were the most significant factors for surface roughness.
All the mentioned materials are the product of powder metallurgy, which offers uniformity of structure and also very small primary carbide sizes - below 5 µm - which has a very positive effect on mechanical properties.
