The results showed that transformation temperature (Af) lowered oral temperature (37oC), this was mainly attributed to the superelastic properties that can be taken into orthodontic applications.
Introduction TiNi shape memory alloy has found extensive applications in the field of surgery and medical appliances etc. [1], because of its excellent corrosion resistance and biocompatibility, fantastic shape memory effect (SME) and superelastic properties.
TiNi is the most widely used material in treatment compared with other alloys because it has excellent properties.
Coefficient of friction during orthodontic treatment is a key factor in determining the force systems required for tooth movement.
Consequently, in this study, the properties of materials were evaluated at oral temperature.

The interaction of both phases upon deformation exerts fairly significant influence on structure and texture formation in both constituent phases and in consequence affects the material properties and its behavior upon further processing.
In general, deformation mechanisms operating within the bands of ferrite and austenite depend on a number of factors like chemical composition, stacking fault energy and initial orientation distribution.
The thermo-mechanical pretreatment included additionally solution annealing at the temperature 1150°C for 3 hours with subsequent water quenching.
With increasing reduction another structural effect was observed, that is the micro-shear bands formed on a background of mechanical twins (Figs.5,6) [6].
Among the important factors, which should be taken into account when analysing a deformation behavior of duplex type steels are preferred orientations after a thermo-mechanical treatment and a development of deformation textures within both phases in the course of cold-rolling.

Finally, parameters affecting the operation accuracy of a press can be subdivided into influenceable and non-influenceable factors [9].
As further shown in [6] it becomes apparent that these two characteristic influenceable and non-influenceable factors are interdependent.

The results are consistent with the bearing properties taken from literature [17].
With increasing press force the symbiotic bearing behaviour is initially characterized by the roller bearing properties.

A double-ellipsoid heat source and the temperature-dependent thermo-physical properties of ZK60 magnesium alloy sheet are employed for performing a non-linear transient thermal analysis by a finite element method.
As a calculated result, the welding voltage, welding speed and the welding current are the main factors to determine the welding seam geometry.
The welding time will affect the heat transfer state during welding transient temperature field, special the ZK60 magnesium alloy has a high coefficient of heat conductivity.
It is same that the welding current is a decision factor during the LMF-GTAW process.
The project is also supported by State Key Lab of Mechanical Transmission, Chongqing University.

And then these specimen’s maximum welding strengths and energy at break point properties that were depend on heating time have been compared.
In welding zone dispersion of reinforcement and orientation could be affected by welding pressure, heating, heating time and some like properties so that cause corruption on unity of reinforced thermoplastic.
For a reinforced thermoplastic material two different types of welding process were compared some properties like joint strength, design of joint etc.
It is, therefore, important to explore the best combination of these factors to obtain the best welding result.
That happens because the fiber adhesion to the matrix is enough according the others to increase of the matrix tensions transfer efficiency through the interface and that is essential to get an elevation of the mechanical properties in the composite.

The main reasons for the influence on the mechanical properties are inhomogeneities in the blend, migration of curatives and contaminations in the feedstock for the D-GTR.
If these problems are overcome, a considerable amount of D-GTR can be added to the original compound without significant loss in properties.

Rapid degradation can deteriorate the mechanical strength and generate a significant amount of hydrogen gas via corrosion in physiological environments, negatively affecting bone healing and the surrounding tissues.
