Radiation-induced swelling is one of the factors restricting an increase in fuel burn-up for claddings made of these steels [1-3].
Swelling, i.e. void formation and growth, leads to fuel pin deformation, thus affecting thermohydraulic characteristics of the reactor core.
Moreover, porosity changes physical and mechanical properties of the cladding material.

In addition to the good mechanical properties in a lot of cases the good maintenance behaviour is an important decision criterion.
On the one hand, this passive layer gives these materials the corrosion-chemical properties of a precious metal.
Mechanical damages of finished products by e.g. scratches or coarse grinding increase the susceptibility against pitting and stress corrosion cracking.
Besides economic advantages the lean duplex steels also exhibit technical advantages as, e.g., higher strength, higher fatigue strength, lower tendency for cold welding, better surface properties for coatings.
The three factors that make up the Corrosion Resistance Factor (CRF) are based on a combination of practical experience, knowledge from recognised experts and research papers.

Si eutectic and dendrite α-Al in the composites was finer than unreinforced, therefore these finer phases in composites was also contributed to increase mechanical properties of AMC such as tensile strength, hardness and wear resistance in addition to good weeting between Al alloy and Al2O3 (see figure 6 as below).
Mechanical properties of AMC with 12,5Vf% Al2O3.
In addition to the nature of Al2O3p is hard, the hardness increased due to some theoretical factors such as residual elastic stress as well as high dislocation density due to particles reinforced, and decrease in grain size or sub grain of the matrix[11].
This is also assosiated with higher hardness and good wetting between matrix and Al2O3p reinforcement since wetting constituted the most important role in mechanical properties of MMCs.
Mechanical properties of Unreinforced and AMC with 12.5Vf% Al2O3p.

Meanwhile, changes in the leaching characteristics and physical properties were analyzed.
Although elevated temperature and freeze-thaw cycles led to the deterioration of geopolymer matrices, the leaching rate and mechanical properties of solidified product were still acceptable.
Geopolymers have been used to encapsulate intermediate level nuclear waste (ILW) such as radioactive Cs and Sr because of the excellent properties such as fire resistance, micro-bacterial resistance and high compressive strength[1,3,4].
Hence, it is of great necessity to illustrate the thermal properties of this geopolymer.
According to the literature, Thermal incompatibility, pore pressure effects and phase transition are critical factors that affect the strength evolution of Portland cement-based compositions at an elevated temperature[7].

The synchronization performance is one of the two basic properties of synchronizer [1].
Influencing factors In order to study the synchronization performance of lock-pin synchronizer, analyzing the effects of various factors on the synchronization time.
The lock-pin synchronizer, relative to the lock ring synchronizer, one big advantage is that the cone radius is not affected by the diameter of the gear.
And analysis the factors like the friction coefficient, engine speed, cone radius, input moment of inertia respectively, how they influence the performance of the synchronizer.

SEM observation indicates that the temperature of a saturated vapor pressure does not affect the formation of the CPC scaffolds’ structure.
Like other calcium phosphates, CPC has low mechanical properties.
This study aims to examine the influence of different reaction temperatures on the structure and chemical properties of the CPC scaffolds.
Hydroxyapatite is a chief material of human bones, and it has good osteophilic properties and osteoconduction, and as a result is a good substitute for impaired bones.
SEM images exclude the temperature of saturated vapor pressure as a factor that influences the forming structure.

., Ltd has researched the road performance of the ionic soil stabilizer, including the technical index of road base course, optimum mixture ratio and the mechanical property index[8].
Jones and Eng[11] has studied a sulphonated oil additive in order to found its action mechanism and characterize its action effect with mechanical property index.
However, the treatment mechanism and controlling factors of the ionic soil stabilizer are so complex that the treatment technology is far from mature, which involved regional geology, hydrology, climate condition and highway criterion.
Similarly, the mechanical properties of clay were also affected by PH.
The size, shape, arrangement, connection and micro-pore characteristics of internal structural units were observed by advanced microscope and SEM analysis to reveal not only the external physical and mechanical properties, but also the internal material transformation process of clay.

Moreover, the physical and mechanical properties of fiberboard were also studied.

Six physical and mechanical properties were tested, namely: density, WA, TS, IB, MOE, and MOR.
The bending strength of the fiberboards is affected by several factors, such as fiber diameters, lumen thickness, and fiber length.
