In this study, some mechanical properties of Al/Al3Zr FGMs were investigated.
The Compression tests were also performed for further investigation of the mechanical properties.
The result is a microstructure that produces continuously or discretely changing thermal and mechanical properties at the macroscopic scale [1,2].
Based on that, the compositional and structural gradients in FGMs are expected to affect their mechanical properties.

A strategy is proposed to cope with combined thermal fatigue and hot corrosion resistance affecting industrial coatings.
It uses a thermo-mechanical model combining the heat transfer conditions, thermal and mechanical properties of the materials and the system geometry.
Other factors may lower the capacity of these layers to protect the substrate against corrosion [17].
As in T2 cycles, the layer reduces the overall fN , the superficial mechanical properties are necessarily less favourable than the steel ones.
The Ti and oxide layers mechanical properties are not taken into account as their properties are not well documented enough.

Next, physical and mechanical tests were done to determine their physical and mechanical properties.
Due to the fact that the mechanical properties of these composites are strongly affected by characteristics of their microstructure, their physical properties such as density, porosity and water absorption were evaluated.
These properties are required in product specifications.
Porosity is damaging to the mechanical properties of these materials.

These factors may directly affect the microwave dielectric properties of the (Ca0.8Sr0.2)ZrO3 samples.
The increase in density may directly affect the microwave dielectric properties In addition, the dielectric constant of the (Ca0.8Sr0.2)ZrO3 ceramics also as a function of its sintering temperature.
Many factors are believed to affect the microwave dielectric loss and can be divided into two categories, that is, intrinsic loss and extrinsic loss [5].
Fig. 4 Dependence of sintering condition of (Ca0.8Sr0.2)ZrO3 ceramics on quality factor (Q´f) and tf Conclusion The microwave dielectric properties of (Ca0.8Sr0.2)ZrO3 ceramics were investigated.
Compared to previous reports, a significant improvement in the dielectric properties has been achieved.

The deformation in machining process, which directly influences the mechanical property, behavior integrity, fatigue life and so on, is the key problem in current studies[6].
The deformation is influenced by the factors of initial stress state, machining process, and form of component[7-9].
Based on the milling simulation, the influence factors such as milling path, clamping position and milling speed are analyzed to propose machining strategies to reduce deformation.
3) how to control factors led to distortion.
The bending is caused by two factors: initial residual stress and machining stress.

The existence of clearance in joints also leads to the impact dynamic load, and affects the transfer of the system load, the destruction and failure of the mechanism.
Currently, the researches of joint clearance are usually focused on the property of materials or microcosmic wear, but research of dynamic wear of clearance joint in mechanical system working in high-speed is less carried out, thus it is necessary to study the dynamic wear of clearance joint.
Vector model of joints with clearance The clearance between joints usually brings about the inside contact which have two properties.
First property is that the system becomes variable topology structural system.
The reason is that the existence of clearance causes the contact force which affects the acceleration of the system.

With these properties, PV panels become more effective and maintain their high transmission for a long time.
Insights and perspectives were also given by focusing on the factors affecting the hydrophobicity and abrasion resistance of ARCs which may help future researchers to fabricate more efficient ARCs.
Accumulation of dust can behave as a barrier for incoming rays that can deteriorate the optical and mechanical properties of ARC.
This review will provide comparisons regarding previous studies to give explanations on how these additives affect the said properties of the ARC by changing their parameters.
The structure of films such thickness and porosity also affect the properties of the films.

The tests of mechanical properties and particularly damp tests were performed.
The properties of the brick can be seen in Table 3.
Thanks to these values, especially the values of porosity, we can estimate the influence of porosity to other mechanical and diffusion properties.
The comparison of surface finishing of these historic full burnt bricks from the point of view of their diffusion properties as well as the course of natural drying and diffusion resistance factor are going to be the goals of the further research.
According to the results it is expected that the goal properties caused the variety of other properties are just porosity and boiling absorption.
