The physical properties of metals remain fairly constant and are not affected by any outside pressure or force.
In dissimilar metals having wide difference in physical and mechanical properties, tensile stress produced is quite high.

For the theoretical study of the rolling process, Forge2011® was employed, which is finite element method-relying software that enables the thermo-mechanical simulation of rolling processes in a triaxial state of strain.
In order to use the results of simulation employing the simplified Archard model for the quantitative evaluation of roll wear, it is necessary to define the factor of wear and the hardness of the tool as a function of temperature.
Introduction The continuous rolling of long products can be ranked among the most efficient processes that enable a long product having high mechanical and strength properties and good quality of the surface to be obtained within a narrow range of dimensional tolerance.
The passes wear during operation, which affects the dimensional accuracy of the finished product and the run of the rolling process [1–3].

Measurements of Rheological Properties.
The table gives the experimental conditions For each feedstock material, there are two factors, namely, temperature (oK) and load (kg) at three levels, 32 full factorial designs was used.
This means that the enhancement in properties is enabled by lubricity of a small addition of graphite to the feedstock.
Hence the three feedstocks can be injection moulded at a wide range of temperatures (which is inevitable due to loss of heat as feedstock flows to the mould), without affecting viscosity of the feedstock.

When these studies are examined, it is clear that workpiece and insert material properties, cutting conditions, and process parameter differences affect the residual stress results.
Key variables affecting residual stress are identified as friction coefficient, tool edge radius, and cutting speed.
Properties of materials used in simulation studies [25-26,28-32].
Material properties of insert and coating [25-26,28-32].
Despite these factors, the small percentage gaps suggest that the simulations are still highly reliable.

The reasons for large deformation properties in Baozhen Tunnel were analyzed and corresponding supporting measures were carried out in this paper.
Analysis of deformation characteristics in Baozhen tunnel Deformation characteristics are influenced by not only the mechanical properties of surrounding rock but also in-situ stresses and construction factors (Liu, 1999)[2].
Curve fracture and break Fig. 1 Failure Characteristics of Surrounding Rock in Tunnel Generally speaking, the process and features of progressive failure are mainly affected by three factors below: (1) The size and state of the in-situ stress.
It is also one of crucial factors, which may bring about geopressure symptoms and mechanical disasters during excavation and maintenance
Fig. 4 Horizontal convergence rate at DK79+127 Fig. 5 Vault settlement rate at DK79+127 Through the analysis above, surrounding rock in Baozhen Tunnel presents properties of large soft rock deformation so the supporting countermeasures should be taken in large deformation part.

So far, more attentions have been paid on the microstructure and mechanical properties of the spray deposited materials.
Investigating the size and distribution of the over-sprayed poeder will be helpful to analyze the microstructure characteristics of the deposits so as to determine their effects on mechanical properties[5].
It can be seen that there existed some smaller pores and atomized particulates in the spray deposited preform, which is bound to affect the mechanical properties of the current materials.
However, the subsequent cooling rate during deposition plays an important role which finally determines the microstructure and mechanical properties of the obtained materials.
Meanwhile, a too high temperature should be limited so as to maintain the RS microstructure and mechanical properties.

In order to understand surface properties of thin films, contact angle and roughness were measured.
Introduction Recently there has been a great interest in nano hybrid of organic and inorganic materials for their unique properties in mechanical, optical and electrical fields [1,2].
The properties of organic-inorganic hybrid coating films are affected by constitution, properties of composition, molecular structure, interaction of chemical bonds [7,8].
A major factor of coating films is chemical bond of organic materials with inorganic particles.
Generally, properties of organic-inorganic hybrid coating films are deteriorated with increasing chemical bond of organicorganic materials.

Cho, has presented the dynamic fluctuation of the thermal shock stresses employing practical inertia quantity and material properties through the orthotropic thick cylinder shell made of glass/epoxy, [4].
Thermal loads are affected by the time periods, the diffusivity property of the material, supplied heat flux and the ratio of the inner and outer radii.
In the cooling case, the transient temperatures calculated are of relevance with a period of time as shown in Fig.4.The roles of the convection coefficient of the forced air with the diffusivity property of the material, in addition to the inner and outer radii have a very important implicit effect in the thermal loading results As well as, the effects of the thermal expansion factor and the stiffness property of the material on the thermal stresses.
The combined effects of the time, material properties and the ratio of the inner and outer radii of the hollow cylinder on the transient temperature gradient are clearly domenstrated.Hence; their functions on the thermal stresses must be taken in consideration.
Also, the thermo-elastic stresses are mostly influenced by the thermal expansion factor and stiffness properties of the material.

As the device size reduces, the power dissipation and thermal management in these nanosize devices become the key factors during the design process.
Among various potential candidates for future MEMS/NEMS applications, carbon nanotubes hold a unique position because of their remarkable properties like small size, great strength, light weight, special electronic structures, huge current-carrying capacity and high mechanical and thermal stability.
Figure 1 - Cross-section of MWNT According to this model, the conductance of a MWNT or a SWNT is determined by two factors namely the conducting channels per shell and the number of shells.
Diameter and length are important factors in determining both magnetic and kinetic inductances.
The total resistance therefore becomes so high that it masks the observation of intrinsic transport properties of a CNT.
