The different types of bending observed in this study is difficult to understand and explain
without further measurements on a larger number of wafers which is on-going.
A high density of threading edge dislocation will stop the movement of basal plane dislocation caused by the temperature induced stress and instead accumulate edge dislocations at grain boundaries.

The XRD pattern was compared to that of the JCPDS file number
20-0532 and with diffractograms obtained from single crystal data.
After 65h, two main peaks are visible which correspond both to a remaining β-FeSi2 phase and to an α-FeSi2 phase with a very small grain size.

Grätzel
and his co-workers reported a high efficient DSSC based on nanocrystalline TiO2 electrode, which
was composed of titania nanocrystalline particles accumulated on a transparent conducting oxide
substrate and achieved a high specific surface area for adsorption of a large number of ruthenium
complexes [�,2,3].
The mean grain sizes are measured with a computer to be 20 nm and the mean roughness (RMS) 0.8.

In Fig. 1, the grains were formed in peaks and valleys-island shaped particles and were clearly
identified.
This means that the size of number of self-similar pieces in TiN coating decreased with an increase in N2 gas flow rate and vice versa.

Performing a certain
number of virtual experiments QF is generated by means of multi-dimensional regression analysis.
A fundamental property of the model consisting of five coupled differential equations is that by taking into account the rate of austenite grain growth, it permits the prediction of the progress of ferrite, pearlite, upper bainite and lower bainite transformations simultaneously [10].

So, a limited number of samples was subjected to analysis.
The sample MJ9 also contains about 10% of aplastic grains but these are made of quartz, plagioclase and metamorphic rock fragments instead of calcite.

If further water is added, the heavier grains settle out
and fine particles are segregated.

Besides the two basic
phases (γ (Ni, fcc) matrix and γ' (Ni3Al, L12) intermetallic precipitates), a large number of
secondary phases may be present in Ni-based superalloys, including carbides, borides and
numerous ordered intermetallic phases, with the most notable being the deleterious topologicallyclose-packed (TCP) phases.
The as-solidified DS alloy UM-F16 was a single crystal alloy with no high angle grain boundaries.

However, an increasing number of studies on the subject have been conducted by several researches in the past few decades [1-12].
The grain size is entirely fine sand with an effective diameter of 0.16mm, and uniformity and curvature coefficients of 1.9 and 1.2, respectively.

Also the change
in the crystal behavior across grain boundaries is important information extracted from this test.
