Whereas the requirements to the mechanical properties of the weld increase, the demands on the component safety are becoming increasingly important.
However, expected welding stresses are usually considered by global safety factors in existing standards and technical guidelines.
The chemical composition and mechanical properties are given in Table 1 and Table 2.
Mechanical properties of the test materials (mechanical testing (a), producer test report (b,c)).
A free shrinking test specimen was welded to get a reference for residual stress and weld properties.

During aging at a relatively low temperature (100 °C) of the PA material, a small increasing of the mechanical properties was detected, which was explained by the formation of atomic clusters, GP zones and β” phase.
During aging at relatively low temperature (100 °C), in contrast to the 75 % deformed material that shows a small variation in their mechanical properties, the mechanical properties, of the 30 % deformed material, are almost constant.
Factors such as low degree of activation during irradiation, high corrosion resistance in vapour–water media, high weldability, medium strength, high extrudability have supported the usage of the 6xxx class of alloys as structural materials in the industry of nuclear research reactors [1].
So, the slight increase of the mechanical properties can be, properly, attributed to the formation of an additional amount of both of clusters, GP zones and β” phase.
Aging of the heavily deformed material, at relatively higher temperature (140 °C), leads to a fast decreasing of the mechanical properties.

The formed parts under a rotary swaging process have good mechanical properties such as surface hardness, elastic limit, tensile strength, compressive strength and bending strength since microstructures of formed materials exhibit fiber structures.
Suffredini [3] investigated the influence of the rotary swaging process on mechanical properties.
The results predict the proper process variables affecting the quality of tube and solid bar product such as dimensional precision and surface roughness.
Thus these factors are considered and selected as important process parameters for cold experiment by the rotary swaging.
From these results, it is found that the dimensional precision of solid bar is slightly affected by variation of the forming speed.

The lapping trace distribution on ball surface is one of the key factors during the lapping process, which can affect the sphericity of lapping.
While lapping trace distribution on ball surface is one of the key factors, which can finally affect sphere-shaping mechanism.
The further study will take more factors such as grid division, abrasive, and material selection, which have great influence on the lapping.
If these factors can be studied, the lapping uniformity of RDP lapping mode can be well validated.

Research based on ultrasonic surface treatment (UST) shows that the operation is beneficial to tribological properties and fatigue life of mechanical structures by enhancing the surface mechanical properties, such as roughness and residual stress, through changing nano-structure induced by severe plastic deformations on the surface.
Surface physical and chemical properties of mechanical components and parts play vital role in those failures.
In 1980s, some researchers found that mechanical properties and surface structure of the material could be altered by applying ultrasonic energy to the surface.
However, most of the studies described above are primarily focused on the change of mechanical properties such as strength and fatigue life.
Basic mechanical properties of the Materials.

Introduction Composite materials have wide application because of their versatile properties which include high strength to weight ratio, high stiffness to weight ratio, design flexibility, good damping properties, and corrosion resistance[1].
The results revealed that there is an enhancement in the mechanical properties of composite materials due to hybridization.
They also performed a parametric study to examine the effect of ply orientations, material properties, element type, and column size on the buckling strength of plates.
Mechanical properties for the same are shown in table 1.

High traffic load and temperature are the two critical issues that affect the quality of asphalt pavement.
However, an important factor for sporadic use and incidence are composite's financial demands.
