On the estimation of temperature boundary of solubility in peritectic systems

A model for describing monoheterogeneity of peritectic systems solid solutions based on the account of donor-acceptor interaction of component atoms in the solid solution transition layers is suggested. For systems Al-Ti, Al-Hf, Al-Zr, Al-Ta, Al-Nb theoretical estimation of the character of chemical bond in the solid solution transition layer atoms is made on the basis of experimental data on solubility temperature boundaries
