The amount (and distribution) of DIM that forms during deformation, or the ultimate fracture, of this steel depends upon several factors: material chemistry, initial grain size, grain orientation, plastic strain, strain rate, stress state, temperature, deformation mode, etc. [12-16].
As a consequence to the formation of DIM, the microstructure changes from single phase austenite to a composite structure, with martensite behaving as a reinforcing phase; this phenomenon significantly affects the mechanical behaviour and enhances the work hardening rate [20].
Fig. 11 TEM bright field image showing (a) the presence of twins and andomly distributed dislocations in monotonic fracture test samples along with presence of DIM whereas (b) cell structure formation is predominant for cyclic fracture specimen In the monotonic fracture toughness tests a part of the supplied energy is used for crack extension by tearing while the rest is used for deformation process.
TEM results in Fig. 11 exhibit randomly distributed dislocation structure in monotonic fracture test specimens whereas diffused sub-cell structure in cyclic fracture test specimens.
It is well known by now that plastic strain gets accumulated in engineering components/structures when these are subjected to asymmetric fatigue cycling and the phenomenon is termed as ‘ratcheting’.

In other words, CFRP demonstrated a more uniform and dense structure with fewer voids.
Fractures were visible, especially in the lower section, but the structure as a whole exhibited better overall properties due to its higher uniformity and denser fiber distribution and better interface bonding, as indicated in Fig. 7.

The adsorption-desorption data were examined to determine the moisture content of the monolayer (3.4-9.7%), properties of sorbed water in porous structures and surfaces, total heat of wetting, net isosteric heat of sorption, spreading pressure, differential entropy, and enthalpy-entropy compensation.
The sorption isotherms adopt a structure that aligns with the type II isotherm class.

Reducibility is defined by mineralogy, structure and porosity of agglomerate materials.
Mechanical durability (Russian Federation State Standard 15137–77) [10] is defined in a rotating steel drum with the subsequent definition of test screen structure change.
The presence in the agglomerate structure of unreacted burden, fragile glass and two-calcium silicate sharply reduces the durability of agglomerate that in turn worsens the gas dynamics of process and reduces intensity of blast furnace smelting.

The plug-in architecture is particularly advantageous to accommodate the intrinsic structure of Eq. (2), which is the real core of the WPPM method.
This limitation has recently been overcome, and a general algorithm now exists for calculating contrast factors for any slip systems in materials of any crystal structure [35].
This is a possible step towards the combination of WPPM with the Rietveld method, using the detailed physical modeling of the line profiles discussed in this paper for a combined structure/microstructure refinement [38,39].
In the example shown in this paper, the entire observed pattern was modeled using six structure/microstucture parameters: a0, ρ, Re, fE, µ, σ.

Crystalline solids will have a more structured molecular arrangement called the Bravais lattice.
Figure 1(a) shows the struvite crystal structure, which resembles the orthorhombic lattice pattern according to Bravais lattice, while Figure 1(b) is the SEM image of struvite recovered from anaerobically digested dairy manure that proves the orthorhombic pyramidal crystal structure of struvite.
(a) Crystal structure of struvite [5]; (b) SEM image of struvite recovered from dairy manure [6] The nucleation process is divided into primary nucleation and secondary nucleation.
Seed materials have a specific surface structure that may provide nucleation sites for the struvite and enhance its growth [7].

Immediately Sir Grove disclosed his “gas battery”, the scientists tried to relate the basic principles of chemistry and electricity, matter and energy in order to understand what cause current to flow between some substances but not others [11].

The Mg-for-Ca or Zn-for-Ca substitution contributes to the stability of β-TCP structure.
Zn ions migrated from Zn-β-TCP to HA during sintering can cause partial decomposition of HA since Zn destabilizes HA structure.

Since the optimization of the varistor properties needs the slow cooling or a low-temperature post annealing, much work was devoted to the structure of GBs in varistors [15, 111, 112].
For example, the TJs in Ref [120, 121] clearly correspond to the scheme Fig. 6d (complete wetting, θ =0°) Intergranular layers in conducting oxides of fluorite structure.
