abstract = {A novel processing method for amorphous Al50Ti50 alloy, obtained by mechanical
alloying and subsequently consolidated by electrical resistance sintering, has been investigated.
The characterisation of the powders and the confirmation of the presence of amorphous phase have
been carried out by laser di raction, scanning electron microscopy, X-ray di raction, di erential
scanning calorimetry and transmission electron microscopy. The amorphous Al50Ti50 powders, milled
for 75 h, have a high hardness and small plastic deformation capacity, not being possible to achieve
green compacts for conventional sintering. Moreover, conventional sintering takes a long time, being
not possible to avoid crystallisation. Amorphous powders have been consolidated by electrical
resistance sintering. Electrically sintered compacts with di erent current intensities (7–8 kA) and
processing times (0.8–1.6 s) show a porosity between 16.5 and 20%. The highest Vickers hardness of
662 HV is reached in the centre of an electrically sintered compact with 8 kA and 1.2 s fromamorphous
Al50Ti50 powder. The hardness results are compared with the values found in the literature.},
