The phase diagram of the Sm–Co–Sn ternary system wa s constructed at 770 K (more than 55 at.% Sn) and 870 K (0–55 at.% Sn) using X-ray and metallographic analyses. Seven ternary intermetallic compounds, Sm3Co8Sn4 (Lu3Co7.77Sn4-type), Sm6Co2Sn (Ho6Co2Ga-type), Sm12Co6Sn (Sm12Ni6In-type), Sm3Co6Sn5 (Dy3Co6Sn5-type), Sm2CoSn2 (related to the Tb117Fe52Ge112-type), SmCo1-xSn2-y (CeNiSi2-type), and Sm6Co8Sn26 (Yb6Rh8Sn26-type), are formed in this system at the investigat ed temperatures.
