These defects, which most often develop from initial corrosion pits, are usually related to the presence of a higher number of corrosively aggressive impurities in the steam that accumulate in a film on the surface of the components during operation or during shutdowns in the wet parts of turbines.
Microstructure of the material was formed of fine tempered martensite with a very small fraction of d-ferrite and a linear network of carbides on the boundaries of austenitic grains (Fig. 6a, b).
They are determined for a limited number of values of the stress ratio parameter R – in our case for three to four values.
So, this risk may be reduced by increasing the number of tests carried out, which, of course, takes time and money.
Another condition necessary for the successful application of the methodology is a knowledge of the history and the outlook for turbine operation, or more precisely for a rotor with blades in terms of the number of starts, shutdowns, operation time periods at limited output, etc.

This increase in number of slip systems at high cutting temperatures could be an explanation to improved ductility of Mg alloys and the resultant continuous chips rather than short breaking chips observed in machining of Mg-Al alloys used in automotive industry such as AM20, AM50, AM60, and AZ91.
Mg-Al alloys with 2 to 9 wt% Al will have more barriers in their dislocations’ path than Mg-Ca (0.8wt%) alloy for the same number of slip systems.
More alloying element in substitutional and/or interstitial form(s) will increase strain fields in both number and intensity.
They used micro grain tungsten carbide inserts.
The FBU formation for the particular case under investigation in this study would be as follow: Stage I (initiation) - thermally softened Mg alloy, with a semi-solid mix at grain boundaries, flows on the rake face of the cutting inserts due to shear action.

However, studies in the subject simultaneously bring a number of issues to light, which require further understanding.
We hold that currently it is viable to concentrate attention on solving the problems of the first stage; interest in such problems is evident in a number of publications [10-14].

Conclusion Based on the above, development of composites for construction printing shall be based on a number of principles.
At that, it is assumed, that adjusting its ratio, coarseness and grain distribution one may significantly influence the efficiency of mold compounds being produced.

Degree of freedom theory, analysis software of EDEM with discrete element and setting periodic boundary model are applied in this paper to simulate the vertical screw conveyor’s grain (rice) delivery process under different intermediate support structure.

A fully recrystallised grain with significant drop in hardness was observed at 1050C.
Accordingly, a number of simulation studies were carried out to understand the hot deformation behaviour.

The average grain size of the synthesized powders was around 200 nm.
The occupation numbers of electrons are expressed Gaussian distribution function with an electronic temperature of kT = 0.001 Ry.
Its mixing factor for self - consistency is to be 0.2 and the number of iterations used in mixing scheme is 5.
(2) Where, n is the number of electrons being transferred during the intercalation process, F is the Faraday constant, ∆G is the Gibbs free energy.

(d) the same way as (b) steps (a)-(d) were repeated up to the desired bilayer number.
Influence of bi-layer number on the CuCl2 rejection and the flux.
The results of these researches indicated that the thickness increased with increasing the bilayer number.
The larger the assembly bilayer number, the lower the permeate flux.

It has been found that fatigue resistance decreases with an increase in the number of cycles.
Every year, for these reasons, more than 15% of rollers in rolling mills and more than 60% in pipe rolling shops fail out of the total number of rollers included in the equipment of these shops.
The samples were polished with a grinding skin with a grain size of 3/0 and then subjected to tempering in a vacuum chamber at 620 ° C for 30 min to remove residual stresses.
It is established that fatigue resistance decreases as the number of cycles increases.

This implies that if the loading is applied on a direction perpendicular to the orientations of the fiber grains instead of the direction along the fiber grains, the stresses in the major planar directions are interchanged.

Therefore, several high entropy alloys have been developed to combat high-temperature corrosion in a number of components [18, 19].
These small-sized dendrites reduce the boundaries of grain sizes and could however enhance the mechanical and microstructural properties of the alloy [35, 36].
The major contribution to the strengthening could also have come from the grain boundaries as asserted by Sathiyamoorthi et al. [49].
