The isothermal section of the phase diagram of the Y–Cu–Sn ternary system was constructed at 673 K in the whole concentration range, using X-ray diffraction and EPM analyses. The interaction between the elements results in the formation of five ternary compounds at the investigated temperature: YCuSn (NdPtSb-type structure), Y₃Cu₄Sn₄ (Gd₃Cu₄Ge₄-type), YCu₅Sn (CeCu₆-type), Y_1.9Cu_9.2Sn_2.8 (CeNi₅Sn-type), and YCu_4.65Sn_0.35 (MgCu₄Sn-type).
