“…From a phenomenological standpoint, it becomes evident that there is a stage where the liquid can efficiently wet a ζ-ζ grain boundary. This phenomenon aligns with the Gibbs-Smith condition [26].…”

The microstructure of the coating during hot-dip galvanizing under industrial conditions of two structural steels, a low-silicon ASTM A36 steel and a high-silicon Q345B steel, both of commercial grade, have been characterized for industrial-relevant times. In both cases, it is noted that the formation of the Fe–Zn phases begins in the early stages in the heating step of the steel, a situation in which all the phases are in the solid state. These last observations have been taken into consideration and the microstructures of short times are analyzed, showing that the effect of silicon is present at longer times. The characterization was carried out through traditional metallographic techniques including SEM-EDS and XRD equipment. The evolution in time of the microstructure of both steels is examined, being able to observe that the mechanism by which silicon accelerates the formation of Fe–Zn phases in galvanizing is related to the presence of the liquid phase in contact with the ζ layer formed in earlier times, accumulating silicon in the ζ–liquid interphase. These results are directing the analysis towards proposing the hypothesis of a mechanism of penetration of the liquid phase through ζ–ζ boundaries by variations in the surface free energies that allow the penetration of the liquid phase according to the Gibbs Smith condition. Finally, the observations provided us with a deeper understanding of the phase evolution in the hot-dip galvanizing of high silicon steels.

“…Quantization on Kahler manifolds in general has been formulated in detail by Berezin [36]. We also note that the usefullnes of Kahler quantization for discretizing de Sitter space was pointed out by A. Volovich in a quantum mechanical scenario [22]. In the present Quantization we are dealing with a field theory with infinitely many degrees of freedom and infinite Khaler matrix variables.…”

“…For pure Gravity in de Sitter space, it has argued that the Entropy being S = A/4G with a finite area of the horizon requires a finite dimensional Hilbert space [19][20][21]. Interesting quantum mechanical models have been proposed [20,[22][23][24] to account for this. But apparent conflicts between a finite entropy of de Sitter space with the usual formulations of dS/CFT have been discussed for example in in [25].…”

We derive a collective field theory of the singlet sector of the Sp(2N ) sigma model. Interestingly the Hamiltonian for the bilocal collective field is the same as that of the O(N ) model. However, the large-N saddle points of the two models differ by a sign. This leads to a fluctuation Hamiltonian with a negative quadratic term and alternating signs in the nonlinear terms which correctly reproduces the correlation functions of the singlet sector. Assuming the validity of the connection between O(N ) collective fields and higher spin fields in AdS, we argue that a natural interpretation of this theory is by a double analytic continuation, leading to the dS/CFT correspondence proposed by Anninos, Hartman and Strominger. The bilocal construction gives a map into the bulk of de Sitter space-time. Its geometric pseudospin-representation provides a framework for quantization and definition of the Hilbert space. We argue that this is consistent with finite N Grassmannian constraints, establishing the bi-local representation as a nonperturbative framework for quantization of Higher Spin Gravity in de Sitter space. 1

“…This ensures the supply of the liquid phase to the initial solid phase and, therefore, the dispersion of large solid-phase volumes. According to Traskine and coworkers [21,22], a continuous network of interlayers is formed, if the proportion of the grain boundaries that satisfy Gibbs' condition exceeds a certain value.…”
