Obtaining new materials with high-quality structural properties is possible using traditional methods [9, 10].
In turn, the form factor in modelling is determined by the random value of these angles, which reflect the individual structural properties of an inhomogeneous medium.

Modular superconducting magnets such as those used in the LHC require connection,
and the joint has to be soldered at temperatures above the melting point of solder without its
properties, in particular current delivery capacity, severely affected.
Nanostructure changes before reactive diffusion are deduced from superconducting properties measurement whereas microstructure and structural changes are detected by microscopy and mechanical testing.
The same batch of samples was used also for superconducting properties measurements, mechanical tests, and metallography.
Superconducting Properties Measurements.
This may be due to the presence of residual stresses or other non-equilibrium factors.

The main factors affecting the safety of electrical equipment mainly from two aspects, the human factor like theft, climbing tower, illegal construction and natural factors like lightning, storms, snow and landslides.
Eddy current flaw detector in actual use would affect by a number of factors, such as changes of ambient temperature, surface hardness, uneven mechanical rotating and jitter.
The using of single eddy current probe is vulnerable to the above factors.
In physical properties, ultrasonic method can measure the thickness, material hardness, hardened layer depth, grain size, level and flow, residual stress and plastic bonding strength.
Compared with ultrasonic detection, its measurement range is relatively small, and is susceptible to a variety of factors.

However, due to this movement, pores among the particles are generated that affects the mechanical properties of the green compacts.
The microstructure changes under this circumstance resulting in mechanical properties variation [15] such as strength, hardness and electrical conductivity.
Therefore, this study presents the investigation of forming temperature to the microstructure evolution and its relation to the mechanical properties of powder compact.
This study can be useful in formulating optimum compaction parameter to desired mechanical properties as well as predicting microstructure and mechanical behavior of the final product, later during sintering process.
Green compact produced is tested for its mechanical properties in order to evaluate the influence of the parameter applied.

With respect to the electrode microstructure, the starting particle size, agglomeration and specific surface area are all important factors affecting the electrochemical performance.
The stated powder properties are closely related to the degree of calcination [6].
Results and Discussion Cathode powder properties.
However, the contribution of the last two factors was obscured by the larger particle sizes of the LSCF-SDCC55 cathodes calcined at a temperature higher than 750 °C, which caused the increment of ASR.

It is found that the static SC factor (SCF) of CFRP plates varies with the dimensionless bore and zigzag angle by a greater change than isotropic plates, and that the dynamic response amplitude and frequency of the SCF depend on the dimensionless bore and the dimensionless wave number related with material properties and the exciting frequency.
The mechanical properties of the material are listed in Table 1.
