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.

PP is a thermoplastic polymer known for its favorable mechanical properties, such as high stiffness and good impact resistance.
By comparing the storage modulus and mechanical loss factor of PP and PP/CNT composites using DMA, one can evaluate the effects of CNT reinforcement on the mechanical properties and viscoelastic behavior of the composite.
These factors can collectively contribute to a quicker degradation speed compared to pristine PP when exposed to hot air conditions.

Mechanical properties especially impact toughness values were increased due to significant reduction in the tool wear.
The peak of temperature of stir zone is major factor which decides the phase transformation and subsequent properties of the joints.
This has significant effect on the tool life of developed tools and subsequent properties of the weld quality.
Further study is required on the correlation of metallurgical characterization and mechanical properties of induction heat assisted frictions stir welding of stainless steels.

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.

The change of each factor will inevitably affect the selection of technology.
It is very complex issue of changes of structure and properties of reinforced concrete.
Therefore, the durability of the structure and properties is not obvious.
According to the existing research analysis on the characteristics of steel corrosion, rust did not change significantly the mechanical properties of steel early.
The change of each factor will inevitably affect the selection of technology.

The machine parts remanufacturing using surface engineering technology, not simply recovers the size of parts, but gives the new surface properties, the hardness, strength, corrosion resistance, even better than the original parts.
In material selection, we should consider the balance between material green property, material function and cost [2].
In the selection of parts materials, in does not affect the product performance, should choose recycled materials.
Economic recovery Economic recovery is parts materials can effectively recover the decisive factor.
Due to the mobile mechanical products are often composed of many different properties and composition of materials, products, waste elimination, how to effectively classify, separation and the parts and materials is an urgent problem to be solved.

Study of Constructive Materials and Structure inside Long Highway Tunnel Based on Environment Factors Xiaoli Shi 1, a, Mengrou Yang 1, b 1 School of Highway, Chang`an University, Xi’an 710064, Shaanxi, China aglxl@gl.chd.edu.cn,b250570967@qq.com Keywords: Long Highway Tunnel; environment factor; reflecting material; noise reduction material; structural optimization Abstract.
Its constructive materials and structure are closely related to environment factors [1] of highway tunnel which include noise, lighting, temperature, humidity, air and landscape, etc.
These factors have a greater influence on the passengers and the maintenance staff inside long highway tunnel.
The special environment of highway tunnel request that the sound-absorbing materials should have the following properties: (1) Eximious acoustic property The same sound-absorbing material has different sound absorption coefficient in low, medium and high frequency, which requires the selected sound-absorbing materials property correspond to the acoustic properties in tunnel.
Conclusions (1)For the selection of constructive materials and structure inside long highway tunnel, the environment factors including sound, temperature, humidity and illumination should be taken into consideration synthetically

The study results of mica bearing rocks from the Mamskoye and Kuletskoye deposits and the processes, involved in grinding and activating muscovite mica from the rocks using a ball and a planetary mills, a disintegrator and a pneumoimpulsive installation depending on different time intervals and other grinding factors, are presented in this paper.
Meanwhile the electrical, mechanical and other properties of the obtained material as well as its further applications are highly affected by the ratio, method and quality of mica grinding.
Muscovite and quartz vary in properties.
A surface appearance of the muscovite, processed in a disintegrator, is characterized by friability and aggregation properties and is radically different from the powders obtained in a ball and planetary mills.
