The object of research: advanced magnetic materials based on Sm-Co alloys, obtained by means of ultra-rapid hardening, drawing intense deformation and heat treatment. Objective: The main objective of the project is to study the structural and magnetic properties of magnetically hard alloys Sm-Co system in the range of 10 to 40 wt Sm concentrations. %. and alloy phase composition stehiomterichnogo Sm2Co17 doped Fe, Cu and Zr. According to the results of X-ray studies revealed that the alloys can obtain a homogeneous microstructure in the nanocomposite asspun state with high crystallization modifications equilibrium phases. The greatest value of the magnetic flux 325 Wb obtained in alloys near the composition stehiomterichnogo SmCo5 phase with 37 wt. % Sm. For the first time studied the Sm-Co thermal stability of alloys, are non-equilibrium state, and the temperature set intervals of reverse magnetic losses that may resuming magnetic properties when re-magnetization. It is shown that the alloy with 40 wt. Demonstrates% recovery record magnetic properties up to 900 0C and the greatest amount of magnetic flux during heat treatment in the temperature range of T = 200-700 0C.
