There are many influencing factors on boric acid corrosions, including the impurities inside the material, oxygen concentration, temperature and pressure [3].
It’s greatly significant to find out the principles of boric acid corrosion and the influencing factors on boric acid corrosions.
At the earlier operation stage of PWRs, material properties of the nuclear equipment were well-balanced, and less borated water leakage occur in borated water system.
Thirdly, check the affected equipment and verify whether borated water was still on the equipment.
Lastly, check the materials of the affected component.

Secondly is the ability of the metallic interconnect to form a thin protective oxide one of the most important lifetime limiting factors for SOFC.
Ferritic steels have a number of advantages, e.g. low surface scale resistance, ease of fabrication, good mechanical properties and excellent thermal matching to the other SOFC components.
The problem of cathode poisoning due to volatile Cr species is well- known and there are numerous publications discussing the mechanism by which Cr affects SOFC performance [1, 2].

It is shown that temperature and air humidity do not affect the crack growth resistance of the peak aged 2022 while these two parameters widely influence the crack growth in the under-aged alloys which exhibit in cold air a crystallographic retarded propagation similar to that in vacuum.
Introduction Due to their good specific mechanical properties, Aluminum alloys are widely used for constitutive parts of aircrafts and thus weight saving is a strategic issue in aeronautics.
New generation aluminum alloys are developed to improve their specific properties including damage tolerance through optimization of microstructures.
The main mechanical properties at room temperature and 223K are listed in Table 1.

SMPU properties can be customized depending on a variety of factors, including molecular weight and type of soft segment, symmetry and type of hard segment, and chain extender which will essentially affect the morphology-property relationships.
PU produced using symmetric diisocyanates and urea as hard segments showed superior microphase separation, crystallinity, good mechanical behaviour and elastomeric properties as compared to unsymmetrical MPDI, TDI and HMDI.
The thermal properties of the PU samples were investigated using DSC analysis.
Shape memory properties of the synthesized PU is summarized in Table 4.

This would affect the solder ball joint strength and causing drop balls issue.
Our research study evaluated whether or not the moisture test affected the solder joint strength in long term aging process.
Reliability Test on TC Temperature Cycles (TC) stress tests were performed to study the mechanical properties and internal structure of polymer core solder balls in this experiment for solder joint strength test and Intermetallic (IMC) measurement.
IMC plays an important role as one of the factors that can affect the solder joint strength performance.

However, due to the slow speed of the alkali-aggregate reaction, destructive effects of expansion appear after 8 years, or even 20 years generally, and there are many factors affect expansion, so controversy still exists on some issues.
Mechanical properties of slate meet the requirements of aggregate, but it has high alkali activity [5, 6, 7].
And k represents the scale factor.

Benjamin M Cook[17] examined composite bonded scarf repairs by experimentally measuring and analytically predicting the residual curing strains and strains due to mechanical loading.
He provided some mechanical property values of IM6/3501-6 composite and FM300-05M adhesive, measured small specimen with moiré interferometry and big specimen with strain gage.
Scarf Repair Structure Finite Element Model Composite main board and patch were all [+45/0/-45/90]S IM6/3501-6 composite laminate, which material property was shown in Table 1; scarf slope was 1:20, adhesive layer thickness was 0.127 mm( as shown in Fig. 1), adhesive was FM300-05M, which mechanical property was elastic modulus E=1.134GPa, poisson’s ratio v=0.38, tensile strength S=29.8MPa.
In patch, stress in the place near upper end of adhesive layer is the largest, so here is the most possible place to be destroyed, place far from damaged hole in main board composite laminate has low stress level, hardly affected by damaged hole.

By its properties, zirconium is very close to titanium, and therefore the manufacture of tubes from this combination, as well as pure titanium, is considerably difficult.
Bimetallic tube products have special physicochemical properties which cannot be obtained in single-layer products but only through special compositions.
Its perspective is emphasized by the fact that aluminum and magnesium having similar properties are not recommended at elevated temperatures up to several hundred degrees, at which zirconium still sustains its strength.
The valuable qualities of bimetal stainless steel + zirconium, combining the strength and the indicated properties of zirconium, make it possible to adopt this bimetal in the construction of atomic reactors [15-19].
In terms of their chemical properties, zirconium is very similar to titanium, and the formation of their alloys largely submit to the same laws, therefore the manufacture of tubes from this combination, as well as pure titanium, is considerably difficult.
