Conclusions

The physical values considered in this work are functions of the binding energy of quasielastic force and are thus in principle equal characteristics of atomic interaction. However, it must be kept in mind that these values are affected to one extent or another by factors not associated with the bond (for example, the structure, presence of cracks, and so on). Furthermore, it is necessary to take into account the methodological characteristics and difficulties of determining these values (errors in measurement and calculation, for example).

For simplicity and accuracy of measuring in a broad range of values of various factors (temperature, pressure), unambiguous interpretation of the experimental results, and so forth the most suitable characteristics of atomic interaction are the moduli of elasticity, Young's modulus in particular. However, it is necessary to compare the results of measuring several characteristics under identical conditions.

Thus, many important properties of metals and alloys and processes that occur in them are determined by atomic interactions, which makes it necessary to use the characteristics of the bond to solve problems of theoretical and applied metal science. However, for successful solution of these problems it is necessary to use different characteristics of the bond and take into account the limitations associated with experimental determination of these characteristics.
