Compared with Mg based alloys, pure iron and its alloy possess better mechanical properties and don't have troubleshotings with H evolution during the degradation.
The metallic affected layer is very thin with a height less than 100 nm based on a generalized surface corrosion with no pitting signs.
It's composed of martensite and austenite phase at room temperature and exhibits better mechanical properties than pure iron.

Jian-Gong Cheng et al reported the dielectric properties of laser-annealed BZN films and found the crystallinity and dielectric properties improved after a postannealing at 400 °C for 2 h in an oxygen atmosphere [10].
These two aspects all will affect the dielectric properties of BZNT thin films.

Introduction The physical and mechanical properties, such as high hardness and strength at elevated temperatures, chemical stability, low friction and high wear resistance, make ceramics more attractive than other materials for many applications.
The studies mentioned above mainly focus on fatigue behavior influenced by the cyclic frequency besides many other factors/parameters.
The study shows that the size of ZrO2 crystal grain is one of the major factors affect the t-m phase transition.
When being destroyed, it induces to t-m phase transition which leads to the improvement of mechanics properties.
The prohibition effect and the improved fatigue properties are helpful to acquire high quality surface in polishing treatment.

The engineering properties of the soils at the tunneling site are given in Table 1. 3D finite element numerical model A 3D finite element method combined with the soil consolidation theory and underground construction unloading theory is adopted based on a commercial finite element analysis program, as shown in Fig. 2.
Table 1 gives the mechanical parameters for the in situ soils.
Geotechnical properties of the soils Layer No.
It should be noted that, other factors, such as, train dynamic loading, surface vehicle loading, and adjacent construction vibration, can also affect the consolidation deformation of the existing structures.
Therefore, the completed numerical analysis considering the above-mentioned factors is still needed in order to simulate more realistic consolidation response mechanism of existing structures.

Although the reinforce elements can improve the strength and stiffness properties, however the machining cost is high as reinforced PEEK is extremely abrasive.

Table 1 and Table 2 shown the factors and their levels and orthogonal design matrix respectively.
It shows that the dominant factor that affect towards machining performance is number of flute, followed by helix angle, rake angle and clearance angle.
Number of flutes is the most significant factor that affects the surface roughness value.

Introduction Carbon nanotubes have been widely used to reinforced composites due to their superior mechanical properties, such as its high elastic modulus, strength, and toughness etc [1,2].
The difference of interfacial mechanical characteristics can lead to a great change of the composite properties, which can be the main factors for the mechanical behaviors of materials [4].
So the theoretical analysis is very important for the interfacial properties of carbon nanotube reinforced single crystal metal.
Molecular dynamics has been widely used to study the interfacial properties of carbon nanotube reinforced polymers [5].
Liu studied the interfacial properties of carbon nanotube and alumina matrix through molecular mechanics simulations[8].

Wear is the predominant factor affecting die life.
However, the material properties and contact conditions vary with temperature.
To predict die wear during warm extrusion where die temperature, being the dominant factor affecting wear, may rise to over 400°C, unevenly distributed, temperature-dependent effects must be considered [2].
Using finite element analysis, detailed information regarding important factors such as instantaneous temperature, pressure, and velocity of each element node, per simulation step of the die, can be acquired[5].
Conclusion (1) Extrusion temperature, extrusion speed, extrusion pressure, and lubrication conditions are the primary factors influencing mold wear

The influence factors on the density uniformity of SiCp/2024Al in the extrusion process were studied in the present investigation.
Those factors contain the extrusion ratio, the extrusion velocity, the temperature and the friction coefficient.
Those factors are all lead to the difficulty of the extrusion process[5].

As for various mechanical properties of bending components, the size effect of concrete material is reflected in the mechanical properties of reinforced concrete structures.
So various mechanical properties exist size effect, especially those are decided by concrete material performance.
In addition, the bond between steel and concrete is affected by many factors, such as space, diameter, appearance, position, strength of concrete and protection layer thickness etc.
But those factors will be changed with the specimen size changing.
That is, the mechanical properties of reinforced concrete structure are affected by the size affect not only of concrete materials but also of components.

On the Relationship between Structural-Elastic Properties of Co-Zn Ferrites at 300 K Kunal B.
The density of any material depends upon two factors, the intrinsic mass of the particles (i.e. mean atomic weight), and the closeness of packing (i.e. mean atomic volume).
These factors are not taken into account in presently applied approaches that in fact lead to the observed difference in the magnitude of elastic moduli.
