SUMMARY
The norm of elastic constant tensor and the norms of the irreducible parts of the elastic constants of the alloys Iron-Silicon at different percentages of Silicon, Lead-Indium at different percentages of Indium, Molybdenum-Rhenium at different percentages of Rhenium, Niobium-Hydrogen at different percentages of Hydrogen, Niobium-Molybdenum at different percentages of Molybdenum, Niobium-Oxygen at different percentages of Oxygen, Niobium-Zirconium at different percentages of Zirconium, Palladium-Rhodium at different percentages of Rhodium, Palladium-Rhodium at different percentages of Rhodium, and Palladium-Silver at different percentages of Silver are calculated. The relation of the scalar parts norm and the other parts norms and the anisotropy of the alloys are presented. The norm ratios are used as a criterion to present the anisotropy degree of the properties of the alloys.
