The use of incorrect GaN and InN anisotropic elastic constants and unstrained lattice constants, or the erroneous interpolation of InGaN elastic coefficients, have led to several errors in the calculations of compositions of ternary alloys based on strain measurements.
For the calculation of composition by mass for each sample, the unidentifiable component of the sub-sample was assumed to contain the same proportions of prey as the identifiable component, and the sub-sample was assumed to be representative of the entire sample [3].
Calculations of body composition were done as described by Reilly & Fedak [ 31].
In each case the resulting calculations of phase compositions are in good agreement with the experimental data reported in the literature.
The model presented enables calculation of the composition gradient in the FGM material from the starting composition of the suspensions, the EPD operating parameters and the powder-specific EPD characteristics.
The database will aid the design of alloys by enabling the calculation of the composition and proportions of phases present in alloys of different compositions.
Therefore, the predefined compositions have an operational advantage (reduced sampling effort) and simplify the sampling design (calculation of sample composition is not needed).
A method for calculation of the composition of Estonian oil shale and its combustion products is based on the various correlations governing the composition of this oil shale, and relations between its components.
Each measurement (spectrum acquisition and calculation of elemental composition) was carried out three times, with 30 seconds of irradiation.
Based on the concept of electric charge state, the simulation calculation of the composition demixing effect was carried out.
