Saegusa et al.[1] pointed out in the theory of organic - inorganic hybrid material that the hybrid composite was the mixture of inorganic and organic materials of subtler level than general composite materials (namely, the nanometer level).
With the development of organic-inorganic composite materials, the new composite of epoxy resin and inorganic materials has become a trend.
Note that all the purchased materials were used as-received without further purification.

Any obturation process involves the filling of prepared root canal using bio-compatible materials like gutta-percha.
The super elastic behavior of nickel-titanium materials provides reversible deformation with 8% strain [2].
Materials and Method Plastic behavior of endodontic file in curved root canal The plastic behavior of dental file in current root canal can be described using load verses deformation curve recorded in between in first yield to collapse point.
Torsion consideration The rotary endodontic files are manufactured using the ductile materials which is weak in shear.

Texture is one of the most fundamental structural parameters in all polycrystalline materials.
For development of new materials with improved mechanical properties, texture optimization becomes increasingly important [4].
Grain orientations, in area adjacent to the contact surface, have an effect on the friction and wear behavior of materials being in contact.
In bcc materials shear stresses are one of the main cause of the formation {011}<100> Goss texture [10,11].

Currently, the key and advantageous industries in many cities in China all consist of automobiles, new materials, new energy, environmental protection and electronic information, so does the ones in Wuhan.
In recent years, the main industries such as transportation equipment manufacturing, ferrous metal smelting, communication equipments, electronic information, electric machinery, etc will keep steady increase and the strategic emerging ones with great rise potentiel as recycling process of the rejected or used materials, food and drinks making and agricultural product processing, new energies, new materials, biomedicals, and laser making, etc should be encouraged.
To respond to the fierce competition, the industrial enterprises must strengthen the study on the production technology and on the product varieties by closely cooperating with the scientific institutes, and colleges and universities, and seek for a optimum combination among materials, technology, and performance in order to implement the upgrade of the industrial production and to promote the adoption of the new product in the market and to reach the aim of high efficiency, short processing period and low production costs.
