Assessment of changes in volume of nickel compounds interacting with the chemical elements

Based on the density reference data of substances in the condensed state the results of concentration of electrons calculations (C electron, mole/cm3) and the coefficient of consolidation (K consolidation) for initial chemical elements and their binary compounds with nickel have been presented. The purpose of the present work is to reveal the possibility of using the normalized value of the volume change as the characteristics, which allows to estimate the intensity of interaction between dissimilar atoms and the concentration of electrons as the structural characteristics of the materials. A correlation was established between the melting point, the elastic properties and the calculated characteristics for a number of Laves phases. For binary nickel compounds as example shown the possibility of using the calculations based on change the volume of compounds to predict the properties of substances.
