In particular the effect of the leaching process on the surface of the sodalite grains at 90 C from 30 to 150 days has been evidenced.
Pictures taken at the beginning and after different days of leaching show that, especially at 90 C, a major number of holes, presumably due to dissolution phenomena, is present in the borosilicate sample.

Still today, despite the intensive developments over the last two decades, the success of MCFC in the emerging field of clean electricity generation industry remains uncertain for a number of not fully resolved lifetime or performance-limiting factors mostly of which are related to metallic corrosion or corrosion-induced component failures.
The only effect of a long-time exposure is the appearance of some grain boundary attack due to formation of (Cr,Fe)2O3 oxide growing into the metal along the grain boundaries.
Steel Time period (hours) 0-50 500 >5000 316L (Fe,Ni)Cr2O4(i); Fe2O3(e) (Fe,Ni)Cr2O4(i); LiFe5O8(m); LiFeO2(e) (Fe,Ni)Cr2O4(i); LiFeO2(e) 310S Cr2O3(i); Fe2O3(e) LiCrO2(i); LiFeO2(e); (Na,K)2CrO4(s) (Cr,Fe)2O3(gb); LiCrO2(i); LiFeO2(e); (Na,K)2CrO4(s) [(i)= internal oxide growing at metal/scale interface; (m)= middle oxide layer; (e)= external oxide layer growing at scale/melt interface; (s)= oxide soluble in the melt; (gb) = grain boundary oxide attack] Finally, an added complication is that the steel corrosion behavior on the cathode side can be appreciably altered by the simultaneous presence of hydrogen on the anodic side of the cell.
It is noticed a compact and sharp crystalline structure with large grains generally surrounded by smaller ones probably due to a Ostwald ripening mechanism.

Fe-(18-20)Cr-(4.5-5.5)Al alloys (compositions in wt. %) and close-to-stoichiometric βNiAl

The reason for it is that α-Al2O3 grows via inward oxygen through oxide grain boundaries the fraction of which decreases during oxidation due to the grain growth process.
It is valid for further growth of unstable aluminas which results in blade-like surface morphology (S2-1 in Fig. 4) with less or more developed blade-type grains.

The parameters of the pore networks, such as radius, coordination number and shape factors of pore and throat are computed.
It is necessary to apply a series of filters to smooth the image, to reduce noise and improve the contrast between grain and void [5].
In this part we compare the three samples in terms of connectivity (coordination number), size distributions (contains inscribed radii, volume, lengths of pores and throats), and shape factors.

The relationship between the deformability and the number of the slip
planes is similarly observed in the plane strain compression tests.
Underlined numbers in the parenthesis indicate the numbers of the observed slip planes.
Fig. 3 clearly shows the good correlation between the flow stress and the numbers of the activated slip planes, i.e. flow stress becomes higher with increasing the numbers of the slip planes.
This indicates that heavy cold deformation is expected to become more difficult with increasing the number of required operative slip planes.
Such extensive formation of the stacking faults must be closely related to the development of the parallelograms as well as the absence of equiaxed cells or sub-grain structure inside the parallelograms.

Studying the effects of hybrid reinforcement made of nano-zirconium oxide and chopped glass fibers for poly methyl methacrylate (PMMA) denture bases, nano- ZrO2 (n ZrO2) at grain sizes (46.7 nm) which measured using Atomic Force Microscopy (AFM) and different ratios on the mechanical characteristics was the aim of this study .To make the pure sample, a 2:1 powder to liquid ratio of typical acrylic resin was used.
It has been established that the average grain size of nZrO2 particles is (46.7 nm).
The glass fibers adhered to the fracture plane and protruded.The number of voids created by the drawn glass fibers was higher in group C than in group B.

These PSB are due to the irreversible gliding of dislocations in well oriented grains, leading to intrusions/extrusions.
Discussion As reported previously [2], the dissipative heat sources (leading to the temperature increase) is related to the dislocation gliding in the well oriented grains giving the Persistent Slips Bands on the specimen surface.
The number of cycles at failure was in the range 104 to 106 cycles which corresponds to the High Cycle Fatigue domain.
If the number of active slips bands decreases, it means that the dislocation gliding is impeded by the solute atoms.
For the A42 steel, there was no free solute atoms in the lattice and the number of mobile dislocations is practically unchanged.
