| Popis: | Ensuring the effective development of industries based on natural resources, taking into account the necessary qualitative scientific justification, balancing the reasonable level of scientific and technological progress, is justified by the creation of new materials with specified characteristics. For this, fundamental studies of the physico-chemical and thermodynamic properties of various systems, in particular intermetallides (MI), are an important applied problem. At present, the study of aluminum-based metal systems involving rare-earth metals becomes especially urgent. The problem of determining the regularities of the changes in the thermochemical characteristics of the IM aluminum-lanthanide systems of the α-Al11Ln3, β- Al11Ln3 and Al3Ln compositions is considered, by refining the values of the temperature and melting enthalpy using semiempirical and calculated methods that allow obtaining fairly complete characteristics on the temperature and enthalpy of melting of the IM compositions of the rich aluminum with a demand in modern technology. |
