Changes of grains surface morphology were observed using Scanning Electron Microscopy and EMA/EDXA was used for chemical analysis of solid corrosion products.
The higher number of dishwashing cycles the more intense formation of the glass surface damage [14].
SEM micrograph of glass grains, barium glass containing Al, after 3 days in dynamic flow-through test at 80°C in phosphate solution (corrosion products).

Furthermore, Y tends to segregate on grain boundaries, twin boundaries, and dislocations at high temperature [5].
The PD spacing  to the [0001] has strong correlation with PD density, defined as the following equation; )1( c    i i N L (1) where Lic is the length of the i th arbitrary line parallel to the [0001] in TEM photos observed with ]0112[ incident beam direction and Ni is the number of intersecting points of planar defects and i th arbitrary line, respectively.
There is no precipitates are observed within grains of the W4 at temperature range of 480 ~ 550K, so it is considered that the cross-slip and/or prismatic slip affects creep rate in the Mg-3mass%Y based alloy as the rate-controlling mechanism at 480 ~ 550 K.

The microstructures at various FRTs show predominantly lath martensite within pancaked grains and comparatively finer lath size has been obtained for the steel processed below 800o C FRT.
In the present steels the Ti/N ratio were quite higher (~8) than the optimum level and thus large number of coarse TiN particles have formed. 740 760 780 800 820 840 860 400 420 440 460 480 Alloy1 Alloy2 Alloy3 Hardness (VHN) FRToC 740 760 780 800 820 840 860 1200 1300 1400 1500 1600 1700 1800 Alloy1 Alloy2 Alloy3 UTS (MPa) FRToC 740 760 780 800 820 840 860 1100 1200 1300 1400 1500 Alloy1 Alloy2 Alloy3 YS (MPa) FRToC 740 760 780 800 820 840 860 10 12 14 16 18 20 Alloy1 Alloy2 Alloy3 %Elongation FRToC Fig. 6.
Carbon Fig. 7 : Variation in mechanical properties of the alloys with respect to carbon content (e) Impact toughness at RT (f) Impact toughness at −40o C Conclusions The following conclusions can be drawn from the present study: 1) The microstructure of the TMCP steels shows predominantly lath martensite in pancaked grains.

The gray blocks are SiC grains from the Si-C reaction.
The small gray blocks are β-SiC grains from the Si-C reaction.
The thickness and density of the struts of the products are decided by the silica content in the C/SiO2 composite that depends on the number of cycles of the impregnation procedure.

In alloy systems, the contrast mainly results from segregation, which is proportional to the atomic number of the components and their concentration [4].
In fact, it should be emphasised that cells are attached by a thin solid neck to the native solid grain as visible in Fig2a.
Grain polygonisation will subsequently occur due to the nucleation in the cell boundaries of arrays of dislocations extending along the growth direction where adjacent columnar bodies with slightly different orientation join.

The average grain diameter, 30 µm, of the present polycrystalline samples is large enough for the effect of grain boundaries on the positron lifetime to be ignored [17].

Pine bark, tree fern, rice husk and wood fibers are a number of natural materials that is used to remove dissolved pollutants from aqueous media as they are inexpensive compared to activated carbon and synthetic resin [9].
The test was used to determine the sediment grain size distribution as well as the D10 sediment size diameter which 10% of the materials are smaller in size and the mean sediment grain size which represented as D50 [10].

Since the differentiation of the material is associated with the aggregation and disaggregation of particles - grains of hydrating materials, the rate of heat release and, as a consequence, the temperature in a thermally open system will change.
From Fig. 7 it is clear that the appearance of a large number of cells of large area indicates the presence of large areas with a constant temperature.
As a result, the basis for predicting strength characteristics can be the Voronoi network [19], built on polyhedra, each of which contains areas filled with material closest to the analyzed structure-forming fraction (grain of the original binder, filler particle, pores [15]) than to neighboring objects.

From Fig. 2(a), it can be observed that the raw tungsten powder has relatively uneven grain size and irregular particle shape, ultrafine particles and ultra-thick “aggregates” existed.
In Fig. 2(c), it can be found that the grain size of classified medium powder is more uniform, and the phenomenon of “folder fine” or “folder thick” is almost disappeared.
This is due to the fact that the sintering process of tungsten is mainly caused by atomic diffusion and creep behavior, and with the increase of temperature, the number of active atoms in the particles also increases, leading to the increase of adhesive surface between particles and the growth of sintering neck, which is conducive to the improvement of porous tungsten’s intensity.
