Phase transitions in bismuth-containing elastostressed AlGaInSbBi–InSb heterosystems

In this paper the features of phase transformations in elastically stressed Al–Ga–In–Sb–Bi heterosystems and its subsystems In–Sb–Bi and Al–In–Bi are discussed. Isotherms for the aforesaid heterosystems and its subsystems are researched at temperatures from 653 to 923 K. The critical temperatures and critical point coordinates of spinodal decomposition of AlGaInSbBi solid solution are determined with regard to the coherent deformation energy. The elastic stresses effect on the thermodynamic behavior of the AlGaInSbBi–InSb heterosystem is investigated.
