In fact, alloy selection for the containment of molten nitrate salts is limited by a number of considerations including the lack of data on corrosion and the influence of these salts on mechanical properties.
The mean grain size was about 100±20μm.

A number of different metals and metal oxide particles have so far been encapsulated into the shell of conductive polymers, giving rise to a host of composites [7–9].
As the B4C concentration increases, the compactness of the sample increases causing coupling through the grain boundaries to become stronger which could enhance the conductivity.

The reasons are as follows: the removed metal is very small to improve the productivity, otherwise, it is easy to form such defects as burns and so on; if the allowance is too large, the cut number will be increased so that the productivity is reduced.
At the same time, abrasive grains are easy to flake and wear.

Fresh concrete may be thought of as a particulate system; a system composed of particles which are not strongly bonded together like the grains of a solid and neither free to move like the elements of a fluid, which are submerged in a liquid medium.
The first step of particle parking is to calculate coarse aggregates numbers in the slump cone, and 3D coarse aggregates are transferred to 2D ellipse plate.

Structure of this material is made up of coarse dendritic grains.
Results include linear source location, analysis of the number of AE events, count rate and RMS.

Its reason is the rollers speed The higher, the rollers to capsule squeezing and tore the greater roles, and rub Make nut shell and grain stripping time is shortened, stripping net ratio decreased, damage rate increase. 2) rollers clearance on stripping net rate, the influence of breakage The rollers clearance on stripping net rate, the damage rate of relationship chart 4.

In this paper, a quantitative analysis method of coal spontaneous combustion is given, and dynamics model is established based on a large number of analysis method of coal spontaneous combustion.
Three 30 L barrels which is full of three different grains that selected by experiment.

This material length scale may be defined, for example, as [1]: l* » c d2/b = c/(br) , (3) where c is a non-dimensional constant, d (m) is the mean spacing between dislocations, b (m) is the Burgers vector, and r (m–2) is the average density of dislocations, calculated as the number of dislocation lines crossing a unit area or as the total length of dislocation lines in a certain volume, divided by this volume.
Ceramics contains weak places from manufacture (broken crystalline grains, cracks from machining or polishing, etc.).

Introduction Open cell ceramic foam filters are utilized in metal melt filtration processes to enhance the quality of the cast product by reducing the number of non-metallic inclusions.
Material and Experiments The material investigated within this study is a carbon bonded alumina (Al2O3-C) with a fine grained microstructure.

In addition, the decrease of optical band gap is attributed to not only lattice parameter and nano-crystal effect but also the influence of various factors such as grain size, carrier concentration, deviation from the stoichiometry and lattice strain Fig. 3 FE-SEM micrograph of FZO nanoparticles with various F doping content from 1 wt.% , 3 wt.% and 5 wt.% calcined at 500 °C (A, B and C) and 700 °C (D, E and F).
