Introduction As the cross geometry of large size H-Beam is relatively complicated, the rolling technology is considerably difficult and the influencing factors for the quality have many varieties.
The relationship between microstructure and mechanical properties model is basically about the prediction model of the relationship between the finished products’ room temperature microstructure and mechanical properties.
The indexes describing steel’s mechanical properties mainly include strength and toughness index.
The mechanical properties was predicted through the microstructure without consideration of the influence of pearlite.

Currently many ways are used to study the mechanical properties of nanoparticle-reinforced polymer matrix composites, and most studies obtain mechanical properties of composite materials, and analyze the effect of nanoparticle type, shape, average particle size, surface modification methods and other factors mainly through experimental research methods.
In fact between the nanoparticles and the matrix the interface layer is really existed, and the nature of the interface layer directly affects the mechanical properties of composite materials [16] [9,10].
Thus, making a reasonable mechanical model will be key to predict the effective mechanical properties of nanoparticle-reinforced polymer matrix composites.

The second option to use fillers is to improve their mechanical properties from different perspectives.
Cloisite includes a wide range of applications that help improve mechanical and thermal properties.
A slight deterioration of the properties can be observed for the plate-shaped filler, but the 8% drop may not represent a significant value compared to other mechanical properties that can affect this filler.
However, the decisive factor for choosing the right filler is, of course, not only creep properties, but the complex results of the mechanical tests and, above all, the particular use of the components made of the modified material.

The consumption of Nylon6 is large among engineering plastics due to its specific properties such as high strength, good abradability and self-lubricity.
However, the polar groups contained in the molecule gives the material a high water absorbing capacity, thus has an effect on its dimensional stability and electronic properties.
The conclusions of the analysis above are as following: The alloy shows best comprehensive mechanical properties when the content of ABS-g-MAH is 15%.

The enhancement is affected by many factors, such as filler size, filler volume fraction and filler dispersion states.
However all these theories related to the filler volume fraction only, and cannot give answers to how the other factors affect the properties of composites.
Such scheme investigates the mechanical properties of composites, focusing on not only the filler volume fraction, but also on the effects of filler size distribution and filler dispersion [5, 6].
Asymptotic homogenization We assume that the microstructure of composite is periodic and discuss the effect of fillers on the effective elastic properties.
Their elastic properties are set to given values.

Structure and Mechanical Properties of Composite Layers Prepared by Laser Alloying of Aluminium Alloy W.
During the laser treatment, a composite layer with much better mechanical properties was obtained comparing the base material.
The mechanical and physical properties of aluminium alloys make its application constantly increasing.
The presence of moisture often results in a significant increase in porosity and surface roughness, which adversely affects the strength properties.
In order to investigate the mechanical properties of the obtained layer, the hardness measurements were used.
