Compounds with a tetragonal structure of the ThMn 12 type have a high potential for creating on their basis permanent magnets with high energy density and operating temperatures up to 150 – 200 °C. In this work, samples of alloys (Sm 1- x Zr x )Fe 11 Ti ( x = 0 – 0.2) obtained by the rapidly quenching method with subsequent annealing were investigated. Depending on the chemical composition and modes of synthesis in alloys (Sm 1- x Zr x )Fe 11 Ti ( x = 0 – 0.2) phases of the ThMn 12 , α-Fe type and a small amount of ZrFe 2 are formed, as well as phases with the Th 2 Zn 17 structural type and TbCu 7 at high annealing temperatures. The best magnetic properties at room temperature are realized in the alloy (Sm 0.9 Zr 0.1 )Fe 11 Ti after annealing at a temperature of 800 °C.
