Study of selected physical and structural properties in the process of primary crystallization in the Fe-Cu-Si-B amorphous alloy

According to literature data, the physical and mechanical properties of amorphous alloys depend on their chemical constitution. Further modification of the physical properties of these alloys may be achieved by proper heat treatment. The paper presents the results of experimental investigations of the amorphous alloy Fe 79,62 Cu 0,38 Si 6 B 14 crystallized by isothermal annealing. The objective of the experiment was to determine changes in selected structural and mechanical parameters during primary crystallization of the alloy examined. Root-mean square (RMS) microstrains, sizes of coherent scattering blocks D, and the lattice constant of the crystallizing phase were used as parameters to evaluate structural changes in the material. The research was based mainly on X-ray diffraction measuring techniques, supported with an appropriate mathematical apparatus.
