Structure and magnetic characterization of amorphous and crystalline Nd–Fe–Al alloys

Glass transition and thermal stability of hard magnetic bulk NdAlFeCo metallic glass

“…It exhibits two exothermic reactions, a lower temperature weak peak ranging from 642 to 754 K and a higher temperature sharp peak, followed by an endothermic reaction of melting. The obvious endothermic peak due to the glass transition is not observed in the trace, and this result is consistent with the others results on NdFeAl-based alloys [10,12]. The broad exothermic peak was also observed in previous work, but this exothermic reaction is still unclear.…”

“…This confirms that the transition is a reversible course. [10,12]. The presence of these nano-crystals greatly increases the viscosity and modulus of the supercooled liquid.…”

Magnetic Properties of Pr–Fe–Al Alloys Produced by the Metallic Mold Casting Method

“…Croat. 11) The origin of the coercivity in these amorphous materials has been studied by various researchers, but is not still clear. [12][13][14][15] In this study, cylindrical bulk specimens of Pr-Fe-Al alloys have been produced by the metallic mold casting technique. The magnetic and microstructural studies of the resultant bulk materials were carried out to investigate the magnetic properties of the Pr-Fe-Al alloys produced by the metallic mold casting method.…”

Deformation behavior and dilatometric measurements of Nd–Fe based bulk metallic glass

“…Recently, bulk metallic glasses (BMGs) obtained in multicomponent (Nd, Pr)-Fe based systems with hard magnetic properties at room temperature have been reported [11][12][13][14][15][16][17][18][19][20]. These systems do not exhibit a distinct glass transition prior to crystallization according to constant-rate heating DSC measurements, indicating a low thermal stability of the supercooled liquid.…”
