Depending on chemical composition, fabrication requirements, and intended service, nickel alloys are heat treated in order to either to produce recrystallized or softened structure, to put carbides in solid solution and produce a coarse grain size for enhanced stress-rupture properties, to put age-hardening constituents into solid solution or, last but not least, to enhance strength properties by precipitation of a dispersed hardening phase [1, 2].
Use of an iterative approach allows estimation of emissivity coefficient in wide range of temperature, however, increased number of iteration could extend that range. 2) The emissivity coefficient of nickel alloy 718 changes with temperature, which follows the expectations derived from similarity of response of other metallic materials.

Since feature detection techniques are to be applied automatically on a large number of images, all digital images are required to be pre-processed to a similar standard.
Another problem is that spectroheliograms are generated by scanning the disk horizontally, and a grain of dust lying on the entrance slit leads to a dark straight line on the image, so we must removal the dust line [15].

This is suggestive; since the dose affects the whole
volume, this dependence implies that the increase of the anomalous contribution, described by SF,
is linear in dimensionality,
The TEM images allowed us to observe nanowires and nonorods emerging from single
crystalline grains (Fig. 2.ii), similar to those previously reported [12].
The increase of ∆χ with increasing dose indicates that their number increases with the irradiation dose, and the power law dependence suggests that they are formed at the crystal surface.

It was made of fine grain cemented carbide and the cutting edge design is specialized
for the machining of aluminum.
This element type is a trilinear element, but a linearized shape function is sufficient for structural analyzes with a reduced number of nodes compared with quadratic elements.

A high number of privately dug wells may lead to groundwater depletion.
However, subsurface rock formations that correspond to the interpretation of surface geology still exist, and based on their physical properties, rocks with smaller grain sizes have higher bulk densities and lower porosities, resulting in higher water content [10].

In citrate solution, copper electrodeposition is highly inhibited and results in a small number of large hemispherical crystals located mainly on top of the solid surface [6], leading the plating layer finer, that means lower resistance coating can be obtained.
During pulse deposition period, charged particles around the cathode is more than that in DC electroplating for the much higher current density, that increases the nucleation rate, leading to a fine grain structure.

The most favored clay is Bentonite, a fine-grained inorganic clay of the mineral montmorillonite [4].
The total turbidity reduction is reached, when the number of protonated amino groups neutralizes all anionic charges [9].

In fact, a large number of HBMCA are used under high temperature.
With the decrease of temperature, the primary γ leads to eutectoid reaction, and the secondary boron carbon compounds dissolve out among the intracrystalline and grain boundary.

The functionalized SBR and skim latex were characterized by determination of weight-average molecular-weight (Mw) and number-average molecular-weight (Mn) using gel permeation chromatography (GPC).
The average grain diameter, roughness and the thickness of film obtained from AFM (Fig. 1(b)) were about 20 nm, 2 nm and 200-400 nm, respectively.
