Hajaligol and Deevi[1] etc. made the strip with 24% Al by rolling water spray powder, in which average grain size is 20μm with good resistance and high heat resistance and it was a kind of very good heat-resistant material.
According to the equation: Ki=∑dj/m, where m is the total number of experiments at level i, dj is the density corresponding to factor j at the level i.

Initial stages of relaxation after deformation with e = 0.2 and = 1 sec-1; the numbers indicate test temperatures
The incubation time can also be calculated from the simplified model.
Most of them can be summarized in the form of the following equation (5) where tip is the interpass time, D0g is the initial austenite grain size and A is the coefficient describing the effect of steel chemical composition.

All diffraction lines were characterized well similar to LiNi0.5Mn1.5O4 crystalline structure corresponding to the space group Fd3m (Space group number No.227,a=b=c=8.170 Å), which showed that Ni2+ replaced Mn2+ in the lattice of LiMn2O4 so that forms a spinel structure of LiNi0.5Mn1.5O4.
The average grain size of the samples can be calculated through the full width of the x-ray diffraction peak at half maximum using the Debye-Scherrer equation D=kl/bcosq, where D is the mean particle size, k is a geometric factor, l is the X-ray wavelength, and b is the half-width of diffraction peaks.

The size of nanosilica particle can be estimated by the intercept method as written below,
l= LTPM (1)
Where l is the average diameter of particles, LT is the total length of lines, P is the number line intersection and M is magnification.

Ceramic membranes provide a number of advantages over polymeric ones including high mechanical strength, temperature resistance, prolonged experimental stability, and ease of cleaning after fouling without affecting the membranes’ capacity to transport molecules.
Point of zero charge was determined by the protocol reported earlier by El-kordy et al. [2]. 2.3 Preparation of clay support, LTA zeolite membrane and filtration experiments The raw clay was grinded and made into a grain size between 160 µm and 250 µm using ASTM standardized seives.

Introduction
The properly designed grooved-rolling process should take into account a number of limitations
that influence its running.
At such a high temperature, a structure of completely recrystallized coarse-grained austenite is observed in the strip, which transforms itself into a coarsegrained ferritic-pearlitic structure during cooling.

However, this system underestimates the measuring volume of porous media such as grain, bread,
and sponge cake [2]; this is possibly due to acoustic energy absorption.
The number of times the water droplet crosses the line marked on the tube at intervals of a few tens of centimeters is recorded during the rise of the bread dough.

Correspondingly, the numbers were 34.7% and 66.9%
after added in pure nano-TiO2 powders.
TiO2 and the activated carbon's intergranulars which are coexistent have produced the close faying surface, have accelerated the degeneration and the migration of organic matter to TiO2 surface, and cause the product to be rapidly separated from the TiO2 grains' surface possibly [28].
