The higher content of chrome element binds larger number of nitrogen atoms.
They suggested that the porosity layer formed above the nitride layer of ε phase is a result of N2 gas formation at the grain boundary that is not observed in this research.
This shows that the nitrogen gas in the present study is not trapped in the grain boundary.

This paper describes an overview of a new meshless solution procedure for calculation of
one-domain coupled macroscopic heat, mass, momentum and species transfer problems as well as
phase-field concepts of grain evolution.
This fact is probably due to the highly convective situations with sharp thermal and solutal gradients, characterized by the low Prandtl (0.01), high Schmidt numbers (100), and high thermal (10e7), and solutal (10e11) Rayleigh numbers.
For the coefficients to be computable, the number of the shape functions has to match the number of the collocation points, and the collocation matrix has to be non-singular ( ) ( ) 1 ; l K l k l n l k l n l l k K ψ α = = Φ = ∑ p p .
The adaptivity with respect to the type of the collocation functions (P-adaptivity) is achieved by enhancing the number of the nodes in a sub-domain (Fig.3 center) or by adding additional functions to the collocation set (augmentation) at the constant number of nodes.
The method can cope with very large problems, since the computational effort grows approximately linear with the number of the nodes.

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.

Various cooling rates and numbers of deformation steps were tested with regard to final microstructure and properties.

Slower cooling rate of 10°C/s was not suitable for the processing of this steel, as it created larger fractions of very fine pearlite in the final microstructure and many very fine carbides at grain boundaries (Fig. 6).

The article lays out the findings aimed to develop the fine silver powder production technique for electronics industry by selecting the variable parameters whereby a number of powder grades can be produced in the existing production environment (JSC “Uralelektromed”, Russia).
Further increase in pH level results in a slight growth of grain size.
The tests resulted in a number of silver powder lots with 600-1500 g in weight.

A number of studies have been carried out on the coil cooling behavior.
Finally, according to the way of meshing, the number of nodes is 4681 (31 × 151) and the number of elements is 4500 (30 × 150).
The node numbers 31, 1209 and 2356 are from outside to inside along the inner diameter side.
The node numbers 16, 1225 and 2341 are from outside to inside.
