Moreover, the largely enhanced electrical conductivity can also be attributed to the microsized Sb ribbons in which small carriers can be effectively scattered by grain boundaries as compared to other structural morphologies such as nanospheres.
The increased thermal conductivity may be resulted from the increased electrical conductivity according to the Wiedemann–Franz law: Eq.4 where L is the Lorenz number equal to 2.45´10−8 V2×K-2, s is the electrical conductivity, and T is the absolute temperature.

Decreasing a to 0.05-0.10 leads to the characteristic long tail in the macroscopic softening curve, caused by crack interface grain bridging; see [12].
Even a number of additional mechanisms can be explained.

The grain size distribution of the recycled aggregate is 6-12 mm; it comes from a real recycling plant, in which rubble from old demolished concrete structures is recycled.
Further tests are needed in order to confirm such numbers, but on the basis of this preliminary results it can be noticed a certain tendency of the ‘Rec’ mixture to show higher tensile creep with respect to the reference mixture.

With increase of ageing time, the size got bigger, so the hardness number is decrease at over aged composite.

In order to respect the standard NFP 18-101, the size of the largest grain of sand is fixed at 5mm.

Introduction The development of transparent conductive oxide (TCO) thin films and coatings has been of great interest as they are an important integral part of a number of electro-optical devices.
The grain size and the surface roughness of GZO films increase with the film thickness.

This method is reliable especially for monolithic materials when the notch root radius is sufficiently small in comparison to the microstructural unit usually represented by the grain size [4].
From the results it seems there is a real chance to use even smaller test pieces when a number of conditions is fulfilled.

In slow cooled 7175-B with lower Zn:Mg ratio, coarse precipitates of globular T-phases (BCC) about 5µm wide are seen at grain terior, along with coarse platelets of M-phases about 10µm in a heterogeneous manner.
Dispersoids E(Al18Mg3Cr2) about 50nm thick are uniformly distributed in both alloys. 7175-B exhibits a number of very coarse M-platelets about 200nm long which are heterogeneously nucleated on the E dispersoids.

Since the discovery of age hardening in Cu-Ti alloys in the early 1930's, there have been a number of reports on the precipitation behavior of this alloy system.[4-7] With a small amount of Ti, i.e., typically less than 1 at%, precipitation can be characterized by the emergence of dynamical contrast effects arising from spheroidally-shaped coherent precipitates in their transmission electron microscopy (TEM) image.
In the DF image, some of the grains exhibit moiré contrasts, with the fringe interval being approximately 4 nm.

Introduction Ladle metallurgy occupies special place in number of priority areas for improving the metallurgical technology aimed at improving the quality and reducing the cost of steel.
The grain size of ferrite and austenite was determined in accordance with GOST 5639 (3.5.5).
