For such applications, corrosion resistance and creep behaviour are main factors that have to be taken into account.
However, this kind of steel is sensitive to the nucleation and growth of brittle intermetallic phases during prolonged exposures at high temperature and especially to sigma (σ) phase [2,3,4]. s phase is mainly composed of iron and chromium and appears in the approximate range of 600-1000°C. s phase is known to affect the mechanical properties by reducing the ductility and the corrosion resistance of steels [5,6].
Thirdly, the influence of the phase on the mechanical properties of the steel was assessed by the achievement of tensile tests.
It means that the diffusion is the limiting factor of the s phase growth.

MRF materials experience reversible changes in physical properties such as viscosity, plasticity, elasticity and shear modulus when subjected to different magnetic fields.
They studied the vibration problem of a simply supported sandwich beam with an MRF core and discussed the variable properties of MRF in structural vibration control.
The natural frequencies and loss factors of MRF sandwich beam are investigated by means of numerical simulating and experimental study.
Al has low damping and relatively high stiffness properties compared with those of MRF.
factors are shifted to a higher lever when the applied magnetic field increases.

The effect of Mg content on the fluidity of the melt as an influencing factor affecting both the process yield and wettability of SiC with molten metal was investigated.
It must be noted that for achieving such improved properties, it is necessary to obtain a uniform distribution of nanoparticles in the matrix alloy.
However, the key factor for obtaining improved mechanical properties for these composites is the proper embedding of nano-sized SiC particles within the Al powders.
The fluidity of these alloys as an influencing factor for powder production process in IPM technique was quantified by vacuum suction method.
As a result of rigorous turbulence created by mechanical agitation, these small droplets may solidify before they wet SiC nanoparticles.

It is found that there are four factors which influence the surface roughness: grits size of flap wheel, polishing time, velocity, and force.
Besides the impressive properties of stainless steel, the smoothed surface of part manufactured is an expected feature for part assembling and aesthetic requirements.
They can be concluded that the rotational speed, applied pressure, hardness of abrasive particles and cooling method can affect the surface roughness obtained.
It has been found that not only the grit size of flap wheel, the flap wheel work-piece contact force and machining velocity were also the significant factors to be well controlled for smoothing the work-piece surface.

Stirring rate, temperature, pH value as well as mass ratio of shell and core are the main parameters affecting the stability of microcapsules.
Melamine-Formaldehyde resin can be used as the wall material for its thermal stability and nice mechanical properties.0ur report mainly focuses on the process of microcapsules.
The interfering factors will be analyzed and then the best condition will be determined.
Results and Discussion The preparation of microcapsules is influenced by several factors.
Therefore, the factors influencing the condensation reaction of the MF resin also influence the formation of microcapsule wall, such as temperature, pH value.

The effect of glassy-phase, using AlN and Lu2O3 as sintering additives, on the microstructure and mechanical properties of liquid-phase-sintered, and subsequently annealed SiC ceramics was investigated.
The effect of additive composition on microstructure and mechanical properties were investigated.
It is well documented that the mechanical properties of liquid-phase sintered SiC ceramics are strongly dependent on their microstructures.
It seems that SiC morphology is not the major factor affecting fracture toughness in the present ceramics.
Conclusions The microstructure and the mechanical properties of liquid-phase-sintered SiC ceramics were affected by the chemistry of sintering additives.

Pore size, pore shape and load are the main factors on the high temperature compression creep properties in porous Cu alloys.
Among these, porosity, pattern of pore and pore size are assumed to be key factors on compression and creep properties, but only a few studies concerning the effect of pore on compression properties have been reported.
It can be seen from Figure 5, the load is one of the gold factors on porous Cu alloy high temperature compression behavior.
Conclusions (1) Pore size, load and pore shape are the main factors on the high temperature compression creep properties in porous Cu alloys.

Technical science defines a lot of different factors, that they may be cause of shorter cutting tool lifetime.
For increase cutting tool durability is necessary maximally possible elimination of these factors.
The steel grade and the manufacturing processes used prior to surface induction-hardening dictate the properties in the unaffected area, which means that a combination of properties can be achieved in one component.

Grewal [4] compared the properties of high-speed elastic cam mechanism for different cam profile.
From Eqs. 1 and 2, facilitating sampling points of the profile, control points and weight factors are calculated and adjusted to optimize NURBS profile.

During the operation of the machine, the rubber seals will be affected by factors such as force, temperature, and speed, which will cause the seal function to be lost gradually or instantaneously.
These factors are divided into two types, those that cause changes in the physical or chemical properties of the rubber belong to the first type; all kinds of factors related to the sealing substructure belong to the second type [8, 9].
These factors need to be taken into account when calculating the life, which involves the statistical properties of the material that belongs to the seal structure and actual testing [10,11].
