Effect of Annealing on the Curie Temperature in the Bulk Amorphous Alloys

Abstract:

The paper presents results of research for volumetric amorphous alloys Fe61+xCo10-XY8W1B20 where x = 0,12 in the shape of plater of 10mm x 5mm x 0.5mm diameter. Amorphous Samales were annealed at 953K for 10 minutes what caused their partial crystallization. As a result of the thermal interference in the volume of alloys, three different crystalline phases were formed aFe, Fe5Y and Fe3B. For samples after solidification and after thermal treatment thermomagnetic studiem were conducted. For amorphous alloys, only one ferro-paramagnetic transition was visible, and for the alloys after the isothermal annealing process there were two inflections on the curve .m0Ms (T) corresponding to the two Curie temperatures. These intersections came from two amorphous phases. As a result of the research, it was found that these alloys crystallized in the primal crystalization. Crystallization was the reason for the increase of the first Curie temperature of the amorphous matrix while retaining its decrease with cobalt additive. The value of the second Curie temperature in the alloys after heating was found to depend mainly on the size of the crystallization products and in particular on the Fe5Y crystallite size.
