The paper presents the results of evaluation of clinched joint properties.
The tension test and microhardness test were used for the evaluation of clinched joint properties.
The following tests were performed for evaluation of the properties of the joints: tensile test and microhardnesses test.
Clinching has proven to be a suitable mechanical joining method for the observed combinations of materials; however, factors affecting the properties of the clinched joints have to be taken into consideration, such as the type of materials to be joined, their position with regard to the punch and die, as well as their thickness and mechanical properties.

The tile is actually transversely isotropic, where its out-of-plane properties are different from its in-plane properties.
In the heat transfer analysis, only conductivity of the material is affected by this assumption and in the thermal stress analysis, only the elastic material properties are affected.
For the undamaged configuration, using constant mechanical properties produces lower maximum von Mises stresses in the tile and underlying structure.
Thus higher stresses are obtained in the analyses where mechanical properties are functions of temperature.
These two factors may generally determine the thickness of the TPS and the material selection.

And the initial cubic γ′ precipitates start to coarsen directionally during high temperature creep, which results in the degradation of the mechanical properties, especially the creep properties.
The gradually change of microstructure results in a deterioration of the mechanical properties.
Therefore, the working conditions and the crystal orientation affect the formation of rafting, which will subsequently affect the creep properties.
Then much attention has been paid to investigate effects on creep and other mechanical properties.
It indicates the superior mechanical properties related to rafting.

This paper will study on mechanical characterization of AFM to meet the minimum cutting thickness and influence factors.
Minimum cutting thickness that atomic force microscope mechanical scribing can reach is connected with the diamond tip radius, the physical and mechanical properties of the material being cut.
In this experiment, the specimen is copper, mechanical properties of material surface had great influence on the machining results.
Nanoindentation measurement of aluminum surface properties was shown in figure 4.
Fig. 5 AFM images(Al) AFM mechanical scratching influence factors based on the minimum cutting thickness.Some other factors affect the minimum cutting thickness, such as the smoothness of the surface, noise and other factors can not be ignored [7].

It is believed that microstructural features such as amorphous phase, grain boundary, secondary phase and intergranular pores contribute significant additional magnetic anisotropy and demagnetizing fields, thus affecting the initial permeability accordingly.
However previous literatures focused more on the effect of the composition-dependent-magnetic properties as compared to that of microstructure-dependent-magnetic properties of ferrites [2, 3].
The wide use of these materials and the general believe that their preparation conditions would affect their physical properties have motivated us to study the effect of sintering temperature on the evolving magnetic and thermo-magnetic behaviour of YIG.
In fact, resistivity is a result of the combined influence of several factors such as crystal structure perfection, grain size, microstructural homogeneity, and Fe2+ ion concentration [19].

Oxidation stability is one of the most important properties of biodiesel, which primarily affects the stability of biodiesel during storage for long time.
Factors affecting biodiesel oxidation stability Oxidation stability of biodiesel is affected by two kinds of factors including: external factors, such as heat, catalyst, air, light, additives; internal factors, such as the type and content of fatty acid methyl ester, the natural antioxidants.
It showed that sesamol and soluble polyphenols had the same properties with BHA and BHT.
Although over-dosing can reduce oxidation stability and in extravagant doses can deleteriously affect other fuel properties.
Further work is necessary to better understand the factors and mechanisms which affect the oxidation stability of biodiesel/petro-diesel blends.
