Thanks to its excellent mechanical characteristics, Titanium rises above the others lightweight alloys [8, 9].
To well assess such an assumption, different aspects should be considered, i.e. the thermal properties of the material, the process temperature range, the microstructural evolutions.
A HSS steel punch with a diameter of 12 mm was used in order to ensure a good mechanical resistance at high temperature.
In practice, the heated surface increases by a factor 100, the specific power reduces by a factor 10.
Considerations based only on the energy consumption may lead to quick solutions that can affect the product performance in use.

Additionally, the diffusion of hydrogen and rate properties are improved with the emergence of magnetic field compared with the alloys processed by rapid quenching only.
In order to improve the hydrogen storage properties, considerable researches have been done such as element substitution [5-8], surface modification [9, 10] and heat treatment [11, 12].
Since rapid quenching can improve the cycle life and magnetic field is a favorable factor for the discharge capacity and high rate properties, it seems like a feasible idea to combine them together.
The refinement of grains is also an advantage for better kinetic properties.
Rapid quenching has a negative influence on the kinetic properties, while it is almost eliminated with the imposing of magnetic field

Solubility of ethanol in diesel is mainly affected by two factors namely, temperature and water content of the blend [7].
Three factors allow full second order polynomial model, to provide a significant information about the output response so α= ± 1.
On the basis of 2k +2k+m, where k=3, number of factors or independent parameters and m is number of replicate center points, The CCFCD provides 20 number of experiments including 8 factorial points (2k), 6 axial point (2k) and 6 center points in each face of factorial space.
The proper mixing of air fuel affects the (a) (b) (c) (d) Fig. 4 Effect of FIP, (a) for BP, (b) for BTHE, (c) for BMEP and (d) for NO of diesel and 5 BED at different Fuel injection pressure (Load =6 Kg and CR= 16) fuel spray formation and initial velocity of injected fuel is directly affected by fuel injection pressure.

The stress may will cause cracking or may also remain in the internal concrete to affect its ability.
Shrinkage is caused with temperature decreasing and temperature cracks occur easily under the effect of internal and external constraints, which will seriously affect the performance of concrete structure.
Whether research on the cracking mechanism of shrinkage of high performance concrete or on cracking mechanism of large volume concrete, it is the foundation of research to respectively quantify these two volume deformations of different properties[4].
The following will simply describe the two methods. 3.1.1 Separation method of maturity concept The descriptions for the characteristics of concrete at early ages often need to use the concept of maturity[7], which not only applicating in the prediction of strength and stiffness, and which is effective tools to set up a numerical model for researching the viscoelastic mechanical properties of the basic creep and stress relaxation.
However, because the autogenous shrinkage is related to many factors, if only to use the maturity as a basis for analysing autogenous shrinkage, the key of the problem is whether the precision is high enough when the maturity is taken as a practical tool.

Abrasive granules and mechanical properties samples preparation.
They were polished to 3 mm × 4 mm × 40 mm by grinding machine for mechanical measurement.
Properties measurement.
During the grinding process, the change of circularity and particle size both affect grinding performance of abrasive, but the particle size was the dominating factor.

For plants that have been operating for a long time, aging becomes an important factor to be considered.
By using plant operating parameters in the form of pressure, temperature, and time of operation and secondary data in the form of thermal and mechanical resistance properties of the material the failure of DMW was analyzed.The sample of DMW shows in Figure 1.
