According to the data of differential thermal, X-ray phase analyzes, as well as measurements of conductivity and pycnometric density, phase equilibriums were studied and phasing diagrams of TlInS2 - CuInS2 and TlGaSe2 - CuGaSe2 systems were created in the entire concentration range. The studied systems are quasi-binary with limited mutual solubility of the components in the solid state. The interaction in the TlGaSe2 - CuGaSe2 system occurs with the formation of one eutectic and one peritectic points, in the TlInS2 system - CuInS2 with the formation of one eutectic and two peritectic points. Eutectic at 1048 K corresponds to 18 mol. % CuGaSe2 and at 945 K 17 - mol. % CuInS2. Solid solutions based on CuGaSe2, CuInS2, like the initial compounds themselves, undergo phase transformations. It is found that in these systems limited solid solutions are formed, which make up 1.5 mol. % at indoor temperature on TlGaSe2 and 0.5 mol. % on CuGaSe2 in the TlGaSe2 - CuGaSe2 system, as well as 1.5 mol. % on TlInS2 and 0.5 mol. % on CuInS2 in the TlInS2 - CuInS2 system. The nature of the interactions of the components makes it possible to assign the presented phasing diagrams to type VI according to Rooseboom.
