Abstract

Ensuring effective development of industries consuming natural resources using scientific support requires creation of new materials with preset characteristics. This requires fundamental studies of physicochemical and thermodynamic properties of different chemical systems, in particular intermetallides (IM). At present, the study of aluminum-based metal systems with rare-earth metals is becoming especially important. The study is devoted to determining thermochemical characteristics of α-Al11Ln3, β-Al11Ln3 and Al3Ln aluminum-lanthanide IM, by refining the values of their melting temperature and enthalpy using semiempirical and calculation methods, allowing obtaining sufficiently complete data sets on of melting temperature and enthalpy of the aluminum-rich IM compounds, finding ready demand in modern technology.
