The ultra high performance concrete is a new cement-based composite material with ultra-high mechanical properties, excellent durability and excellent volume stability.
So its quality will directly affect the performance of concrete.
(5) Poor conservation system will affect the improvement and application of the strength of concrete.
Currently, as technical and price factors in the practical engineering, conservation system will not be paid attention to, which will extremely be detrimental to increase the strength of ultra high performance concrete.

Wang et al. [7] studied the effect of mechanical stirring speed on the microstructure and properties of the coatings.
Properties of composite coatings Ni-P-WC nanocomosite coatings.
Nano-Al2O3 particles could enhance the mechanical properties of the Ni-P alloy coating obviously.
However, the concentration of nano-SiC particles is not the more, the properties are the better.
Thus hardness variations, corrosion or erosion–corrosion parameters differential and other factors must not be related to the structure of electroless asdeposited and composite coatings.

For both steel pipe piles and concrete pipe pile joints, the codes don’t consider the dissolved oxygen, Anaerobic organism and other corrosion factors.
No matter it is for steel pipe piles, concrete pipe pile joints, or reinforcement concrete filling pile, this evaluation method that does not consider corrosion factors including dissolved oxygen, resistivity, anaerobic organism and so on is clearly unreasonable.
Table1: Parameters of physical and mechanical properties in Xiangshan Port seabed soil No.
But, the amount of Cl-and SO2-4,anaerobic sulfide and SRB index are the main factors affecting steel corrosion. 3.1 The Process of Corroding Cell.
The inorganic acids, organic acids, sulfides, etc. produced by the metabolism enhance the corrosivity of the environment, and create the conditions for the formation of micro cell corrosion such as local cell corrosion caused by the oxygen concentration difference on metal surface; 3) affecting the condition and property of the metal surface.

However, the local heating produced by both FSW and FSP can leave a fusion zone with reduced mechanical properties and a heat-affected zone with tensile residual stresses that can be deleterious to fatigue performance.
FSP was found to increase the fatigue strength of the Ni-Al Bronze by 70% without affecting the corrosion behavior of neutral salt solution.
Casting porosity provides fatigue nucleation sites that can be eliminated, as the overall properties are improved, by FSP.
A tensile test was performed to establish the properties of the as-received NAB material, prior to FSP, is shown in the table below.

It is widely used in military science field, and it is manufactured the penetrators as the main materials at home and abroad because of a series of excellent mechanical properties, corrosion resistance and absorption ability of radioactivity substance. the research of temperature effects on the mechanical properties of tungsten alloy were less reported.
The experiment researched the dynamic tensile property in the furnace by the high temperature heat furnace of Instron-3112(10℃/min).
(a) 10 ℃ (b) 700 ℃ Fig.3 Fracture surface of 93WNiFe alloy at different temperature The ultimate strength δb of tungsten alloy is influenced by the following factors in relative microcosmic: bonding phase strength δM, tungsten particles cleavage strength δW, tungsten particles and bonding phase release strength δW-M, tungsten-tungsten particle separation strength δW-W.
It illustrates that ultimate strength of tungsten alloy is closely related to the fracture morphology, meanwhile the fracture mode is affected by temperature. 3.3 Substance Analysis In the fracture observation, it also found that there was bright white materials on the surface of tungsten particles and tungsten particles with the bonding phase interface of fracture of tungsten alloy at the temperature 500-700℃ in Fig.4.
(2) The ultimate strength of tungsten alloy is related to fracture morphology closely, meanwhile the fracture mode is affected by temperature

At the present time, although the technology of electroplastic drawing and electroplastic rolling have been realized [2,3], the mechanism of electroplastic effect is unclear up to now and the influencing factors of electroplastic effect still lie in exploration.
In the 1960’s Troitskii and co-workers found that drift electrons can exert a force (electron wind) on dislocations and further affects metal’s plastic flow.
Conrad considered that drift electrons not only could exert a force (“electron wind”) on dislocations but also affected the process of thermally-activated dislocation motion.
Molotskii’s idea that the electron spin may participate in formation of crystal plastic properties in a magnetic field allows one to create a new effective method of plastic properties control.
The theoretical results showed that a microwave magnetic field could cause transitions between magnetic sublevels of a dislocation–obstacle pair and, influence the plastic properties of the crystals.

The mixing quality of rubber compound directly affects the quality, performance and longevity of the rubber products [1].
This paper takes two different tread rubbers to make two-stage mixing experiments in different process parameters such as rotor speed and filling factor, and study their effects on the properties of rubber compound.
Mooney viscosity is an important indicator to measure the flow properties and processability of rubber compound.
After the second stage mixing, GOTECH curometer is needed to test the vulcanizing properties of the two formula rubber compounds.
(2)The temperature rise during mixing process is related to the rotor speeds and the filling factors.

Hence, it was found that the bath concentrations affect the particle size of as-synthesized Co nanoparticles and finally changed the properties of final product.
Consequently, certain mechanical and corrosion properties can be optimized during material processing due to the control of particle size.
Corrosion properties.
The corrosion and mechanical properties were enhanced with the reduction of particle size.
In conclusion, the properties of electrodeposited Co such as corrosion properties and microhardness are strongly affected by the molar concentration of Co.

Fire resistance of concrete is affected by factors like the type of aggregate and cement used the temperature and duration of the fire, size of the structural member, and moisture content of concrete [1].
