In particular, Cu-Zn-Al foams present good pseudoelastic properties and they are potential candidates for damping applications [1-2].
This final procedure does not affect the Cu-Zn-Al foam structure.

Then, some martensite remains retained after each compressive cycle, thus affecting the transformation level measured in the next cycle.

In the present work, the rheological properties in terms of shear stress and viscosity of Kaolin/Polyether-Sulfone (PESf) of varying ratio were investigated by a rotating rheometer.
As discussed, one of the factors affecting the distortions of the spinning suspension is the rheology characteristic.
To understand the behavior of the suspension especially during the spinning process, the rheological properties of the suspension at different material ratio and shear rate need to be studied.
Viscosity vs Shear Rate Conclusions In this study, the rheological properties in term of rheology properties (constants, shear stress and viscosity) for Kaolin-PESf suspension with various kaolin ratios were investigated by using a rotational viscometer.

The fabrication is a key process for the preparation of ceramic tool materials, which governs the mechanical properties of ceramic tool materials under the condition of the same compositions.
The technology parameters, including fabrication temperature, pressure and duration time, affect the microstructure evolution and finally govern the mechanical properties of the ceramic tool materials under the condition of the same compositions.
Sintering temperature and duration time significantly affect the mechanical properties and microstructure of Si3N4 matrix ceramic tool materials [2].
The difference between fabrication parameters leads to the difference between mechanical properties of Al2O3/SiC [3].
The different fabrication temperatures can be chosen according to the properties of the initial powder and the expected mechanical properties of compact.

Abstract.
The joint is the key to the design of structure, so it needs further research on the mechanical properties.
In the connection of beam-column, when the column joints using screw connection and under the shear force, the cotter hole of thinner thin-walled bar will be increased gradually, affects the mechanic behavior of the joints.
Because axial compression ratio had great influence on mechanical properties of node, under different axial compression ratio, the bearing capacity, stiffness etc of two types nodes were analyzed and discussed by finite element method to provide reference for the engineering application.
Study the Mechanical properties of joints under different axial compression ratio, there are five conditions: fully restrained at the top of the column, axial compression ratio is 0.2, 0.4, 0.6, 0.8.Apply load on the cantilever end of beam, loading controlled by the displacement, loading level is multiple of 10mm,such as 20mm,30mm and so on, loads on the joints to their failure.

This study explored the effect of VS processed FDM fabricated PLA products on the mechanical properties, specifically the strength.
Hence, this may also affect other product properties [6].
Birosz et al. in agreement with Fernandez-Vicente et al.’s research, studied the effects of infill patterns to mechanical properties.
Substructure (Infill pattern) significantly impacts its resulting mechanical properties [12].

Mechanical properties data onto investigated CP Ti.
There are many reasons for bad fatigue life, especially strong influence factors are porosity.
Therefore, according to the existing literature, if the pore size is smaller than 100 μm, It is considered that the fatigue characteristics are not adversely affected in addition to the mechanical properties.

One of the factors that affect the EMI method application is the ambient temperature which not only influences the structure, but also the PZT transducers [[] G.
If the properties of the structure change, its mechanical impedance will change, and simultaneously the electrical impedance of the PZT transducer coupling vibrating with the structure will change and display through its self-sensing properties.
That is, the change of PZT’s electrical impedance reflects directly the change of the structure’s properties.
Small change in temperature can lead to changes in PZT properties.
This is because the impedance of piezoelectric ceramic material as a reflection of its electric properties is related with how much that the atoms or molecules inside the piezoelectric ceramics can bind the electrons.

For HA coating, two
factors are of primary importance [3].
The first is whether the changes in the composition and properties of the coating materials damage their in vivo performances.
The nanostructure have better mechanical property and stable in vivo, perhaps this is one of factors why the WS samples have most pushed-out strength between implants and bone.
However, completely crystalline HA coating is not absolute good since the completely crystalline HA coating would have worse mechanical properties and inhibit both cell proliferation and alkaline phosphates activity [6,7].
In addition, the amorphous phase and nanocrystals were also beneficial in inhibiting crack formation and better fatigue properties than a crystalline coating, Therefore, it is important to retain some amorphous phase and nanocrystals in the coating to enhance the mechanical properties [6,8,9].

Influence of polishing parameters on machined surface roughness 4.1Influence of polishing pressure on machined surface roughness Keeping other factors constant, changing the size of the polishing pressure, have a significant impact on the machined surface.
Thus, under the conditions of the other factors constant, the control polishing pressure between 0.2 N/cm2 and 0.6 N/cm2 allows filling polishing liquid between the polishing base plate and the artifacts, and the abrasive particles are crushed thinned to expose a new surface and sharp, favorable chip rolling treatment of the machined surface, thereby forming a good machined surface. 4.2Influence of polishing pad on machined surface roughness The polishing pad is the important part in the mechanical polishing process, the polishing pad must have a good corrosion resistance, hydrophilicity and mechanical properties.

Mechanical properties of the Me-SSQ/CE hybrids were studied systematically.
SEM images accord well with the mechanical properties.
Introduction Cyanate ester resins (CE) become more and more attractive for its excellent properties such as mechanical properties, dielectric properties, hot/wet resistance and processability [1].
SSQ is of great interest because of its excellent properties including mechanical properties, thermal stability, especially for its low dielectric constant [5].
The reactivity is a vital factor to determine the curing techniques, even the final properties of materials [14].
