Phase Transitions in Bismuth-Containing Elastostressed AlGaInSbBi–InSb Heterosystems

The specific features of phase transitions in elastostressed Al–Ga–In–Sb–Bi heterosystems and In–Sb–Bi and Al–In–Bi subsystems are discussed. The isotherms of this heterosystem and its subsystems are studied in the temperature range 653–923 K. The critical temperatures and the coordinates of the critical points of the spinodal decomposition of the AlGaInSbBi solid solution have been determined, taking into account the coherent deformation energy. The influence of elastic stresses on the thermodynamic behavior of the AlGaInSbBi–InSb heterosystem is studied.
