Ti addition into Fe-Cr alloy increases the number of cation vacancies in Cr2O3 scales [7,8], and may promote the outward diffusion of cation at the initial stage of oxidation.
XRD patterns of 96 h oxidized Fe-20Cr series alloy In general, SEM morphology observation on alloy surfaces after 96 h of oxidation test show that fine grained Cr2O3 was formed on the samples (Fig. 3a,b&c).
TiO2 particles on the scale surfaces are still few in number and TiO2 continous layer was not formed at the surface.
Ti addition into Cr2O3 scale will create additional number of Cr vacancy, electron and hole concentration.
SEM observation on the surfaces of Ti containing alloys show that the TiO2 particles on the scale surfaces are still few in number and not continuous.

Note that the numbers shown in the figure stand for the number of cycles, and that arrows indicate shape recovery by heating [6,7].
Some of them were mechanically crashed into powder with the particle size of 100~160mm which was comparable or smaller than the grain size.
Compression tests of the silicone/PFPs mixtures revealed that the elastic modulus was decreased with increasing the number of PFPs.
It is clear that MVR is not recognized for the composite with 0PFP (PFP-free), but MVR clearly appears with increasing the number of PFPs.

A number of non-steroidal ecdysone agonists or bisacylhydrazines have been synthesized as novel pest control agents [10-12].
Fig. 1 Structure of a typical ecdysone, showing the numbering of the carbon atoms.
Experimental Insect Martianus dermestoides Chevrolat (Coleopteran, Tenebrionidae, a kind of stored grain pests), was originally collected from Shenyang city, Liao-Ning province, China, and raised in laboratory without any contact with insecticides since 2005.
Total number of normal eclosing adults was noted.
Daily observations were carried out to record the number of the dead individuals was determined as well.

In the
metals literature these approaches are referred to as micro-macro models; a term first coined by
Rappaz and co-workers to describe models of grain growth in equiaxed dendritic alloys [2].
The model half-arm space is located in a larger domain of the mushy region-the Representative Elementary Volume (REV)-which has a scale of ~10 mm and contain a number of primary dendrite arms or grains.
Assuming that the solid growth in the REV is close to parabolic the modified Fourier number can be estimated as 1m n g 3 4 + +α=α − + (21) When this model is used with the profile back-diffusion model a variable exponent m is calculated with Eq. (12).
This closure requires that a number of model choices be made.
Coarsening is well modeled by enhancing the solute Fourier number via the expression provided in Eq. (21).

Table 1 The ideal grain orientation of five kinds of aluminum alloy drill pipe [5].
Table 3 Equivalent sliding system number (ESSN) and Schmid factor (SF).
It has been reported that the planar anisotropy of aluminum alloy is closely related to the grain structure and crystallographic texture of the alloy, and the crystallographic texture is the main reason for the plane anisotropy [13].
It is necessary to control the content of <223> along transverse direction (TD) and improve the texture content of <101> etc., which has the high equivalent sliding system number and is helpful to improve the comprehensive mechanical properties of material in TD.

Novel, energy efficient separation/beneficiation technologies will be needed to shift the current mining
paradigm towards the exploitation of natural mineral deposits that are very fine-grained (below 20 µm
particle size).
The first issue strongly reduces the number of collisions with the gas bubbles in the flotation cell while the second one prevents overcoming the energy barrier of the particle-bubble interaction after a collision.
Aspects of these techniques are covered in a number of earlier reviews [7, 8, 9, 10, 11].
In Eq. (1), n0 and nc refer to the number of fines and the carrier particle, respectively.
The resulting circumferential velocity, u, can be used to establish a corresponding Reynolds number Re = ul/ν.

The metallographic structure was
polygonal ferrite and the ferritic grain size number was 8 to
8.5 according to JIS in all the specimens.
Whereas the concentration of solute Ti was nearly zero and the TiN precipitation came to an end in the portion to which N diffused, the TiN precipitation did Fig. 10 The number of intersected per unit area of slip plane.
Here, letting ns be the number of particles intersected by a unit area of a slip plane, the relationship between L and ns is expressed as L = ns -1/2 (2) This equation has been obtained assuming that the particles are spherical.
In the case where the precipitate particles are spherical having a radius of r, to begin with, ns is equal to the number of particles in a parallelepiped including a slip plane and having a height of 2r, as shown in Fig. 10(a).
Letting f be the volume fraction of a particle and nv the number of particles per unit volume, f is given as the product of nv and the volume of a particle.

Computation procedures produce a single number output (e.g.
The standard output of ANOVA is two numbers: a quotient (usually denoted as F) asymptotically convergent to F distribution and an associated pValue (also often denoted as pV or pVal), evaluated from this quotient and two degrees of freedom related to a number of groups and a number of the total data.
The microstructure of the IN 713C consists, regardless of the casting parameters used, of γ-grains, interdendritic (γ+γ’) eutectic, (γ+MC) eutectic, carbides and coherent γ’ precipitates distributed uniformly within the γ-matrix.

The AN sample contained equi-axed grains with grain sizes of about 3-5 μm, and a few dislocations in the bulk.
In the AN sample, a microstructure of three grains is seen, with one dislocation.
The simulation of the relative number of annihilation events, using GEANT4 [39], resulted in a total of 10.3% in the Al sealed source and the Hostaphan foils.
Numbers with no errors were fixed in the fit.
This is about the maximum number of components the fitting procedure can handle.
