Material properties Every material has different physical and mechanical properties.
And the Important mechanical properties are young’s modulus, shear modulus, specific stiffness, and strength to weight ratio etc… Quantitative properties Such properties can be expressed numerically.

Careful structural investigations and mechanical testing of the coatings are required to find the interrelation between the definite structural characteristics and exhibited properties.
This type of the dependence of the wear resistance on the amount of the entered energy also assumes the presence of additional factors.
To establish these factors, the structural investigation and measurement of alloying element concentrations in different phases of the coatings were carried out.
The coating obtained with the average amount of the entered energy exhibits the best combination of mechanical properties and wear resistance.
To obtain the coatings with given combination of properties, all structural factors determining these properties should be taken into account.

Ultrafine-grained materials show superior mechanical properties in terms of strength and ductility compared to conventionally grained (CG) materials, which makes them especially interesting for light weight construction in the automobile industry due the high specific strength and the high potential for cost reduction [3, 4].
Friction stir welding is found to be a desirable joining technique for UFG materials, since it provides excellent mechanical properties and retains the fine grained microstructure [11, 12, 13].
Four different areas can usually be differentiated after FSW: the base material, the heat affected zone (HAZ), the thermo-mechanically-affected-zone (TMAZ) and the nugget, affected by the mechanical movement of the pin and the temperature increase.
It increases by a factor of two from the as-received CG state to the UFG state after 8 ARB cycles (Fig. 2 b).
Generally, the FSW AA1050 Al sheets in the UFG state show no significant degradation of the mechanical properties in comparison to the as-received state, while the accumulative roll bonded and friction stir welded Al alloy AA6016 shows a considerable increase in the maximum burst pressure as well as the maximum von Mises equivalent strain with increasing number of ARB cycles.

The models were set to be axisymmetric ones, which would greatly increase the speed of calculation without affecting the result.
The element type and meshing The models used a plane axisymmetric quadratic element, PLANE82, which can be used to be not only plane element but also axisymmetric element, and it also has many properties such as plastic, creeping, radiation expansion, stress stiffness, large deformation and large strain[3].
Many factors impact the K value interactively or independently, such as structure, material, mechanism, technology, stress, and so on[4,5].
