The current work aims to investigate the influence of the aforementioned factors on the predicted FLD of Ti-6Al-4V.
The nature of the imperfection can lie in different factors, such as surface roughness or a macroscopic defect.
For the FLDs of Fig. 5a, the quasi-static hardening properties along the rolling direction are used for the fitting of the hardening laws.
Hence, the FLD is negatively affected.

Factors Influencing Corrosion Substances that cause corrosion of aluminum aerospace alloys are called corrosive agents.
Some factors that influence metal corrosion and the rate of corrosion are; type of metal, temper, grain direction, anode and cathode surface areas, temperature, humidity, presence of electrolytes, availability of oxygen, stress on the corroding metal and time of exposure to a corrosive environment.
Since the material of a component is subjected to corrosion, it is expected that its critical mechanical properties will vary with increasing service time, which must be taken into account for the structural integrity calculation of the component.
Many factors influence aluminum aerospace alloy corrosion such as type of metal, temper, grain direction, temperature, humidity and availability of oxygen.
Some common Al-Cu, Al-Zn and Al-Li aerospace alloys and their composition were given in a Table and some common types of corrosion affecting these alloys (General, Pitting, Crevice, Galvanic, SCC, Exfoliation and Fatigue) were discussed.

Based on the above considerations, the present work attempts to use MgO as binder for magnesium borate whisker (MBOw) perform, and investigate the effect of MgO coating on structures and properties of the whisker perform and composite.
As a result, high-strength perform is not prone to deformation and is favorable to prevent micro-crack generation during composite squeeze casting, which contributes to the improvements of properties and yield of as-prepared composites[4].
Additionally, MgO content can affect the maximum deformation resistance of correspongding.
Moreover, perform fabrication needs moderate whisker coating ratio because the structures and properties of as-prepared composites using squeeze casting method are influenced by many factors[5].
Though compression tests at room temperature were performed for estimation of perform relative strength in the present study, there is a great difference in stress state of composite between mechanical testing machine and actual fabrication by squeeze casting.

Experimental work shows uncoupled transfer functions vary over time and by enough to significantly affect squeal predictions.
Initial research focussed on using the frictional properties of the contacting materials to predict the occurrence of squeal.
While it is clearly important to understand the tribology of the system it is equally important not to neglect the surrounding system properties.

Electrospining can produce fibers with different diameter in nano range, and the electrospun nanofibers have a variety of unique properties such as, specific surface area, higher mechanical properties, high porosity and continuous fibers [1-3].
Mechanical properties of electrospun Polyethersulfone membrane were investigated by a universal testing machine (3 ton, Instron, USA) at ambient temperature.
The mechanical properties of electrospun PES membrane with different concentration of PES was studied.
The mechanical properties like ultimate tensile strength and strain at break are mentioned in table 1.
Generally, increase of flux depends on two factors, i.e. hydrophilicity and porosity [32].

High nitrogen stainless steels with excellent mechanical and corrosion resistance properties is focused on to develop a new class of engineering material.
Introduction High nitrogen stainless steels, particularly high nitrogen austenitic stainless steels becoming an increasingly important new class of engineering material, because their mechanical and corrosion resistance properties are surprisingly improved by the addition of nitrogen to them[1].
Up to now, people have achieved lots of knowledge on the melting technology, properties and microstructure.
In the paper, nitrogen solubility behavior in liquid and solid stainless steels, nitrogen alloying kinetic factors, and nitrogen behavior during the solidification of high nitrogen stainless steels have been discussed to develop high nitrogen stainless steels in a large scale in China.

The reflection coefficient of the coating depends on various factors, in particular, surface microrelief, crystallite size, and the degree of perfection of the crystal lattice.
Defects of this type have a significant impact on virtually all (including optical) properties of solids.

The study of the influence of the physical and mechanical properties of concrete on various hydraulic binders on the corrosion resistance of steel reinforcement has been carried out.
Over time, the pH value of the medium falls, which reduces the protective properties of the film.
Modification of the structure of cement stone due to the introduction of finely ground additives is aimed at creating additional factors that contribute to the protection of reinforcing steel in concrete structures.
Subsequently, steel reinforcement ceases to perform its functions, and the structure loses its operational properties [8, 17].
