The calcination temperature and the pretreatment of interconnect are considered to be crucial factors affecting the ASR property of LCN CCM for application in stack.
And Cr will also transport to the cathode side and block the electrochemical active sites, which can degrade the property of the cathode and the overall performance of the stack [2].
For a high performance CCM, it should possess the properties as high conductivity, reasonable coefficient of thermal expansion (CTE) with the adjacent materials and good sinterability to ensure high mechanical strength within the CCM layer [5].
Thus ceramic-based material with suitable properties is still the best candidate as CCM.
Calcination temperature can affect the particle size and the compactness of LCN.

One of the most important mechanical properties of each material is its strength.
Main goal of this paper is proposal for modification of the raw materials composition and autoclave regime of aerated concrete using aluminium hydroxide in order to improve final mechanical properties and mineralogical composition.
The reaction might be accelerated by content of Ca2+.[8] Materials and Testing Methods An important factor affecting the formation of tobermoritic phases in the C – A – S – H system is the molar ratio CaO/SiO2.
In general it can be stated that Al(OH)3 is suitable admixture which improves mechanical properties of final product and ability of CSH phases crystallisation to tobermorite.

TBCs are known for the high hardness and remarkable tribological properties, making them suitable for industrial applications [3].
However, the work carried out so far did not consider yet an important aspect of thermal spraying technology, which is surface residual stress, an essential parameter in industrial design, significantly affecting the fatigue life of coated parts [4].
The residual stress in coating caused by some factors, such as phase transition and plastic deformation and so on is small at present and the thermal residual stress is main, that is ascribed to the difference of the physical properties between coatings with substrate material.
Thirdly, the differences should lie corresponding to the thermal physical properties.

Introduction Water-proof of cement concrete bridge and lasting properties of asphalt concrete pavement layer is serious problems faced by road construction field[1].
There shall be better anti-high temperature performance, anti-deformation ability, and sufficient shear properties and binding ability based on construction conditions, use environment and horizontal relationship[5,6].
Successful application of rubber-asphalt in deck water-proof is definitely to effectively bind asphalt concrete layer and deck panel as one whole so as to prolong use life of deck[7,8].Therefore to carry out systematic analysis and research on interlaminar shear properties through indoors test is of important realistic meaning.
Test plan Carry out indoors shearing test to determine horizontal shearing strength of rubber-asphalt as water-proof tack coat of cement concrete deck and systematically research affect on interlaminar shearing strength by factors such as asphalt spray amount (which is thickness of water-proof tack coat), use amount and size of gravel spread, interface situations of cement concrete deck panel, and environmental temperature, and change regulations.
y = -0.0004x2-0.0457x+1.7502 R2=0.9616 (2) Conclusions Systematic analysis and research were carried out on interlaminar shearing performance on water-proof shearing performance of rubber-asphalt based on indoors shearing test to determine all kinds of factors and regulations affecting interlaminar combination stability, with the following main conclusions obtained: ① In order to promote interlaminar shearing effect of water-proof tack coat of rubber-asphalt, it is suggested to spread clean gravel with particle size of 2.36~4.75mm and spreading amount controlled at about 10 kg/m2.

Based on individual mechanical properties of these phases, a 3D coupled Eulerian Lagrangian heterogeneous model was developed.
Issues such as composition, heat treatment and the processing method affect physical and thermomechanical properties of materials and their microstructure.
These factors in turn affect machining behavior during subsequent processing by machining [1-3].
Indeed, for example, a greater hardness of the material will result in a greater wear on the cutting tool, thereby affecting the surface integrity of the component and increasing the costs of the machining operation.
For an accurate microstructure modelling, an RGB based mapping algorithm was developed to assign specific properties to the FE elements in function of materials micrograph.

Effects of GNPs-C0890 loading variation to the mechanical tensile properties and fracture morphologies of NR/EPDM nanocomposites rubber blend were studied.
In this paper, NR/EPDM rubber blend filled with untreated and non-covalent treated GNPs at various loadings were prepared and tested for their mechanical tensile properties.
The difference in morphological character of the treated and untreated GNPs may affect the mechanical tensile properties and the fracture morphologies of the composite.

The mechanical properties of clinched joints are influenced by several factors, including the geometry of the joint, the thickness of the materials, and the specific aluminium alloy used [9- 11].
The fatigue life of clinched joints is significantly affected by factors such as loading frequency, stress amplitude, and joint geometry [18].
Both are known for their favourable mechanical properties and are widely used in the automotive industry to produce various components.
Then, the material was rapidly quenched in water to preserve its enhanced properties.
This suggests that while the mechanical properties vary among the alloys, the joining process maintains a relatively stable forming force across different material combinations.

The simplified structure should satisfy analytical requirements of mechanical properties, and be close to the actual engineering structure as much as possible.
As the piston rod and the axle integrally are connected by a sleeve, too much contact in the finite element settings will affect the calculation efficiency and results.
Therefore, the non-key parts which do not affect the analysis of key parts should be simplified.
(a) the elastic force curve (b) the stiffness coefficient curve Fig. 5 The stiffness characteristic and curves The main factors that affect the stiffness characteristics of the shock absorber are the initial inflation pressure and volume of the cavity.
The factors that affect the damping characteristics are the damping orifice, valve diameter and number of valves.

The results showed that the microstructure of X80 steel affected the properties of corrosion product layers.
Therefore, compactness of the deposit layer is a main factor that affects the protectiveness of the steel.
Conclusions Studies of the effect of the microstructure and corrosion time on corrosion properties of X80 pipeline steel in an alkaline sand soil has been carried out.
The corrosion morphology and properties of X80 steel were dependent on the integrality and compactness of iron oxide deposit layers which was through a physical blocking effect to afford the protection.
