“…Heat treatment of amorphous alloys may consist of annealing leading to relaxation of the amorphous structure and annealing resulting in full crystallization of metallic glasses, which in this case is disadvantageous due to the degradation of the properties of such materials, including, for example, loss of high corrosion resistance, as well as a significant increase in brittleness, preventing their practical use. Much more advantageous for metallic glasses is annealing, as a result of which the amorphous structure relaxes, as this phenomenon usually leads to preservation and sometimes even improvement of the desired physical and mechanical properties of metallic alloys [6][7][8]. The reasons for the properties of improvement of amorphous alloys after heat treatment are constantly discussed; therefore, more research is needed in this area [1,4,9].…”

Al-Y-Fe amorphous and nanocrystalline alloys are characterized by a unique collection of diverse properties that are influenced by various factors, including heat treatment. In this paper, the effect of heat treatment on the structural changes and selected properties of Al-Y-Fe metallic glasses in the as-spun state is investigated. The structure of the Al88Y7Fe5 and Al88Y6Fe6 alloys was examined by X-ray diffraction (XRD) and Mössbauer spectroscopy (MS). The corrosion resistance of the samples was characterized using polarization tests in a 3.5% NaCl solution at 25 °C. The effect of sodium chloride on the surface was studied with scanning electron microscopy (SEM) and energy-dispersive spectroscopy (EDS). The magnetic properties of Albased alloys were explored using a vibrating sample magnetometer (VSM). It was revealed that the tested alloys show better properties after annealing than in the as-spun state. The annealing of the Al88Y7Fe5 and Al88Y6Fe6 alloys in the temperature range of 200 to 300 °C improved the magnetic properties and corrosion resistance of these materials. After 3,600 s, the better EOCP values were recorded for the Al88Y6Fe6 and Al88Y7Fe5 alloys after annealing at 300 °C and 200 °C, adequately. On the basis of the polarization tests, it was concluded that the electrochemical properties are better for Al88Y6Fe6 alloys after annealing at 300 °C.

“…With the increase of the magnetic field strength, the permeability of the powder cores after annealing was further improved. The amorphous alloy has high magnetic thermal stability when annealed below the crystallization temperature and above the glass transition temperature [8][9]. Proper heat treatment can improve magnetic stability [10] and eliminate the stress caused by rapid cooling of thin strip [11][12].…”

Since Fe-based amorphous alloys are widely used in magnetic separators, sensors and other fields, it is of practical significance to carry out research on amorphous strips used in this field.The effects of annealing temperature on the soft magnetic properties of Fe70.43Nb10.77Si15.77Cu2.34B0.69 amorphous nanostrips with 25 μm and 28 μm thickness prepared by the single roll cold method were investigated at 20 and 300K.Five specimens were annealed at472.12K, 672.12K, 772.12K, 822.12Kand 872.12K, respectively, and their microstructure and magnetic properties were tested viametallographic microscopy, X-ray diffraction, and vibrating specimen magnetometer. At cryogenic temperatureof 20K, specimens annealed at 672,12K exhibited the best magnetic properties, including the coercive forceof8.1265A/m, saturation magnetic induction intensity of1.4351T,and its residual value of 0.2462T. The comparative analysis of experimental results obtained strongly indicates that the soft magnetic properties of the amorphous alloy are significantly improved by the particular annealing treatment.
