Fabrication and soft-magnetic properties of Fe–B–Nb–Y glassy powder compacts by spark plasma sintering technique

Approach of the spark plasma sintering mechanism in Zr57Cu20Al10Ni8Ti5 metallic glass

“…Moreover, many experiments on various metallic powders showed that oxide is broken at the particles surface during current heating which significantly improves the sintering [13]. Consolidation with SPS of atomized MG powders has thus been obtained for Fe-based alloys, with good magnetic properties [14,15], for Cu-and Ni-based alloys with high hardness and strength [16,17]. The technique has also shown further perspective for the development of architectured materials with the fabrication of in situ composites (devitrification in powder fabrication [18] or during SPS [19]), ex situ composites by powder mixing [20,21], or dual amorphous materials [22].…”

Microstructure and properties of spark plasma sintered Fe–Cr–Mo–Y–B–C bulk metallic glass

“…Spark plasma sintering (SPS) is rapidly evolving as a flexible process for fabricating traditional difficult-to-sinter materials and novel nanocrystalline/amorphous material (nanoceramics, nanocomposites, bulk metallic glasses and functionally graded materials) [1][2][3][4]. By combining the effects of uniaxial pressure and pulsed direct current, the process offers enormous possibilities of fully sintering these materials at significantly lower temperatures and shorter sintering times (less than an hour) compared to conventional hot sintering.…”

Thermal and soft magnetic properties of Co40Fe22Ta8B30 glassy particles: In-situ X-ray diffraction and magnetometry studies

“…The structural relaxation upon isochronal annealing could enhance the spin-exchange interaction through decreasing the average distance between magnetic atoms, 28 which improves both the saturation magnetization and Curie temperature of the milled ribbons (Fig. 3 and 4).…”
