“…Many previous reports have explained crystallization as an exothermic reaction based on DSC analysis. 23 No significant mass loss was recorded after 800 °C in TG/DTG analysis but an exothermic peak accompanied by an endothermic one was visualized in the DSC curve which may result from the phase transformation of β-Ca(PO 3 ) 2 and α-Ca(PO 3 ) 2 (these types of phase transformation were reported at high temperature 24 ). From the TG data, about 75.21% mass remained and if the free water percentage (2.42%) is counted the remaining mass is 77.63%.…”

Fe-rich soft magnetic alloys are candidates for applications as magnetic sensors and actuators. Spring magnets can be obtained when these alloys are added to hard magnetic compounds. In this work, two nanocrystalline Fe-Zr-B-Cu alloys are produced by mechanical alloying, MA. The increase in boron content favours the reduction of the crystalline size. Thermal analysis (by differential scanning calorimetry) shows that, in the temperature range compressed between 450 and 650 K, wide exothermic processes take place, which are associated with the relaxation of the tensions of the alloys produced by MA. At high temperatures, a main crystallisation peak is found. A Kissinger and an isoconversional method were used to determine the apparent activation of the exothermic processes. The values are compared with those found in the scientific literature. Likewise, adapted thermogravimetry allowed for the determination of the Curie temperature. The functional response has been analysed by hysteresis loop cycles. According to the composition, the decrease of the Fe/B ratio diminishes the soft magnetic behaviour.

“…The possibility of weight and size reduction with a low impact on the environment of the equipment that contains them was due to the development of amorphous and nanocrystalline systems [2,3]. Since these have improved the magnetic characteristics compared to crystalline systems [4,5,6]. Today, the urgent need to reduce environmental pollution worldwide has changed the situation, and just as at the time the oriented grain systems displaced products such as double pickled sheets due to their better efficiency, currently, amorphous and nanocrystalline materials are taking parts of the FeSi market due to the global pressure toward renewable energies.…”

The aim of this work is to analyze the possibility of producing a joint by lamination of an Al-1050 plate and Fe78Si9B13(%at.) soft magnetic ribbons material obtained by a rapid solidification process by using the Melt Spinning (MS) technique. The lamination conditions are studied on the characteristics of the joint, the microstructure, and the magnetic properties. Mainly the surface preparation, temperature, and reduction of thickness. The material is characterized by X-Ray Diffraction, Optical, and Scanning Electron Microscopy, showing a completely amorphous structure before and after the collamination, the typical defects caused by this rapid solidification technique in ribbons (bubbles, dust particles, roughness imperfections and oxides) and the joint between materials. The microhardness Vickers has been determined in both, the ribbons as quenched and collaminated samples, to observe quantitatively the hardening suffered during colamination and find a possible cause. The Differential Scanning Calorimetry and Compositional Analysis by EDS techniques were also used to determine the crystallization temperatures and chemical exact chemical composition of the ribbons as received. The magnetic hysteresis curve of the amorphous ribbons showed a Hc and Ms around 3.8 A/m and 1.44 T correspondingly.
