Al-La-Ni-Fe bulk metallic glasses produced by mechanical alloying and spark-plasma sintering

Synthesis of Al–Y–Ni–Co composites by mechanical alloying and consecutive spark-plasma sintering

“…The presence of carbon impurities originating from the decomposition of toluene under milling can be responsible for the observed changes in structure. Similar carbon impurities were found during mechanical alloying of Al-La-Ni-Fe system in presence of heptane [24], where good compacts were obtained after SPS.…”

A Novel Approach to Develop Chalcogenide Glasses and Glass-Ceramics by Pulsed Current Electrical Sintering (PCES)

“…In the literature, the sintering of glasses by SPS mostly concerns conductor metallic glasses (Li et al, 2009;Shin et al, 2010& Choi et al 2007). These glasses which composition can include several chemical elements among Zr, Ti, Al, Cu, Pd, Mg, Pt, Ca, Fe, Ni, Co and sometimes rare earth are largely studied for their good mechanical properties.…”

Deformation-induced crystallization in amorphous Al85Ni10La5 alloy

“…Consolidation of semi-amorphous aluminum powders by equal channel angular extrusion in the temperature range of 200-300 • C was shown to result in very heterogeneous deformation of the compacted material [13]. Spark plasma sintering can be successfully performed at lower temperatures [14][15][16], but only temperatures above the crystallization onset yield samples with low porosity. Consolidation of nanocrystalline Al-based alloy by cold-pressing did not result in bulk amorphous alloy but retained the crystalline state of the alloy [17].…”
