Commercially pure iron powder has been processed by the capacitor electrical discharge consolidation technique. This consolidation technique applies an external pressure and, at the same time, heats a metallic powder mass by the Joule effect of a high-voltage and high-intensity electric current. In this work, a capacitor charged at low voltage...

In this work, the obtaining of amorphized ferromagnetic particles by mechanical milling has been studied. For this purpose, the compositions Fe₇₈Si₂₂ and Fe₇₈Si₉B₁₃ have been studied and the results have been compared in order to determine the best characteristics achieved with this technique. The behavior has been studied when other elements...

The crystallization process, both at the initial and subsequent stages, of amorphous Al88-RE4-Ni8 alloys (RE = Y, Sm and Ce) has been studied. Additionally, the consequences of adding 1 at.% Cu replacing Ni or Al were studied. The stability of the amorphous structure in melt spun ribbons was thermally studied by di erential scanning...

In manufacturing processes using powder metallurgical methods, one of the most important and most expensive parts is consolidation and subsequent conventional sintering. Electrical discharge sintering (EDS) is a manufacturing process that converts the two steps of consolidation and conventional sintering into a single step. Additionally, the...

The technique of sintering by electrical discharge of capacitors (SEDC) is investigated, using a commercial stud welding equipment adapted to be used in the sintering of amorphous powders. In this technique, pressure and the heat generated by the Joule effect from the high intensity electric current are applied simultaneously to a mass of...
