摘要：
From measurements of temperature dependences of the birefringence and from observations of the domain structure the x, T-phase diagram for the Rb2xTl2(1-x)Cd2(SO4)(3) solid solutions have been obtained. Ferroelastic domain structure and movement of phase boundaries have been studied in the course of phase transitions in Rb2xTl2(1-x)Cd2(SO4)(3) crystals. Possible reasons for the appearance of mechanically non-compatible ('forbidden') ferroelastic domain walls are given.
