The pitting corrosion resistance of weld metals produced by different consumables is discussed in the paper in terms of the pitting resistance equivalent number (PREN) calculated from the chemical compositions and the content of delta ferrite in the austenite matrix of the weld metals.
The austenite grains with twins were observed as a typical microstructure of stainless steel base metal.
The empirical relationship between the degree of pitting corrosion resistance and the contents of those elements was formulated as the following equation [7] and well known as a pitting resistance equivalent number (PREN) PREN = (wt%Cr) + 3.3 (wt%Mo) + 16 (wt%N).
The pitting resistance equivalent number (PREN) of the weld metals produced by the AISI 309L, AISI 316L, and AISI 308L consumables were 25.3, 23.0 and 18.6 respectively. 4.

Grain sizes in most crystalline materials (like metals), usually dictates its strength.
The addition of heat modifies the grain structures of a material, this also known as recrystallization; a process wherein on a specific temperature range, new set of equiaxed and stress-free grains are formed.
This zone is also known as the recrystallization zone – the area where the grain sizes grow.
To determine the best parameter combination on the given numerical data, the numbers were plugged in to SAS-JMP software for prediction profiler analysis.

Additionally, it was observed that starch grains were adhering to the fibers, exhibiting a spherical morphology.
Wave numbers within the range of 2850-3000 cm-1 correspond to the C-H stretching bond, whereas the specific wave number of 1315 cm-1 signifies the presence of a C-H stretching bond.
The wave number falls within the range of 1000-1320 cm-1, indicating the presence of a C-O stretching bond.
The wave number falls within the range of 675-900 cm-1, indicating the presence of a C-H bond within an aromatic group.
The wave number range of RS when compared to RSM exhibits similarities.

Some combinations of Nb, Mo, Zr, B and C resulted in refined grain sizes, increased recrystallization temperatures, and improved strength of Fe-28Al-5Cr [5].
The maximum number of electrons is 30.33 at -0.85 eV energy level, and the electron number at the Fermi level is 18.05.
The electron number is 15.62 at the Fermi energy level.
The electron number is 16.25 at the Fermi energy level.
The electron number is 19.04 at the Fermi energy level.

The necessity for high performance and lightweight structures and the tendency of incorporating an increasing number of tasks in each part can be made to happen by coalescing various materials into a multi-material hybrid structure.
The fractograph (Fig. 13a) had signs of different grains getting fractured through them (transgranular fracture) separation (see, white colored rectangles in Fig. 13a) between different grains have white coloured boundaries.
Some indications of tear up (showed using black circle in Fig. 13d) through few grains were noticed along SS side (Fig. 13d).
The fractograph (Figs. 13e and 13f) showed signature of tear up (black circle in Figs. 13e and 13f) through few grains along both Ti6Al4V and SS sides, which indicated that DCJs processed for 120 min showed transgranular fracture behaviour.
Different grains were fractured through them (transgranular fracture phenomenon) and were separated through the white coloured boundaries (identified using white colored boxes in both Figs. 13e and 13f).

HPW and CsHPW are highly dispersed in the SiO2 at the low loading, while the loading is more than 40%, the catalyst grains increase and gather on the surface of the carrier.
On some supports, the heteropoly structure is retained but the smaller particle size allows access to an increased number of surface protons.

Natural pearls are formed when a small foreign object, such as a parasite, grain of sand, or piece of food, lodges itself in the gonad or mantle tissue of a mollusc or oyster.
Measurements: X-Ray Diffraction (XRD) analysis was carried out for grain size determination of nano crystalline materials and peak profile analysis on fine powder of pearl sample to investigate its microstructure.
The small spikes in the XRD pattern indicate the presence of small sized grain in it.
The functional group region shows absorption marked wave number between 4000 to about 600 cm-1 as shown in Figure 5.

Chip formation study will always be relevant in analyzing metal cutting because it present the grain deformation pattern in the chip morphology, enhance the understanding of the Built-up-edge (BUE) phenomenon and it makes clear the alteration of tool geometry due to tool wear [7].
It has 1.5GPa compressive proportional limit and grain size varying from 1-2μm.
Also, the localized shear bands were absent and the grains became squashed and stretched as they pass through the chip root zone.

We used the model proposed by Koops, according to which the sintered polycrystalline material consists of grains and intergranular layers.
Moreover, the electrical resistance of the latter is much higher than the resistance in the bulk of the grains due to the different content of Fe2+ ions in crystal lattice [37, 38].
To ensure a change in the valence of such a number of iron cations, ~ 5 % of oxygen atoms must evaporate.

This increase in the mean surface roughness might be related to the film structure throughout the growth mode of the grains, chiefly the Stranski-Krastanov mode.
In this mode, the formation of grain boundaries with limited pores is observed.
