The effect of Cu content on the microstructure and properties of Cf/ZrC composite ceramics were investigated.
Based on this, Ni was added into the complex to prevent the chemical injury of carbon fiber by Deng Qichao[6], leading to the production of (Ni,Cf)/TiC-TiB2 composite ceramics with excellent mechanical properties.
We conclude that because the strength of the composite ceramics is a very sensitive quantity which can be influenced by many factors.
Under the certain of components, porosity and phase components are the two key factors.
Of note, the substrate of the material plays key roles in affecting the strength of the Cf/ZrC-xCu strength ceramic composites.

The thermal energy that the arc provides melt the workpieces and the filler metal, thermally affecting the surrounding metal.
Grain size is one of the dominant factors that influence mechanical properties especially in solid-solution strengthened materials.
Welding process will change the structure and by consequence the mechanical properties of the metal.
It is obvious that FSW joints exhibit better mechanical properties than those obtained by TIG welding.
Silicon content affects the properties of the weld in the same way it affects the as cast metal properties, that is higher hardness values and lower tensile strength values in both cases.

Interface mechanics characteristics and the mathematical model 2.1 Interface mechanics properties The mechanical characteristics of interface experiment results show that surface roughness is one of the main factors of mechanical properties.
The factors of soil’s gradation, density, grain shape also has important influence on the mechanical properties of the interface, in addition, the method to stress, boundary conditions and the stress path may affect the interface mechanical response.
As well as the elastic-plastic constitutive model, there is no elastic-plastic constitutive model can well and comprehensively reflect the main mechanical properties of the interface.
Because the soil-structure interaction mechanism is very complex and the influencing factors are various, the mathematical model which describes the mechanical behavior is very complex too.
Theory research is to solve the reason of the interface shear zone and the mechanical properties of the shear zone, and provide the basis for reasonably determining constitutive model.
