Abstract
The phase composition and microstructure of Fe5Co70Si15B10 obtained in a nanocrystalline state by crystallization of the initially amorphous alloy were studied using electron microscopy. We applied the crystall ization at 923K for 10 s to refine the grains in the alloy and to comp are ifs magnetic and mechanical properties with those of the alloy cry stallized by the conventional procedure. Rapid crystallization of a me tallic glass at an elevated temperature under rapid heating and coolin g was shown to result in significant gain in the coercive force, reman ent magnetization, microhardness and strength.
