Abstract
Fe-base Superalloy/Al2O3 type composite compacts were successfully obtained
by spark plasma sintering from mechanically alloyed powders. The superalloy
powders without Al2O3 and superalloy/Al2O3 type composites powders with 5
and 10 %vol. Al2O3 were synthesized from elemental powders in a high energy
planetary mill. The influence of the milling process on particle size
evolution has been determined using a Laser Particle Size Analyzer with an
analysis field of 0.1-1000 ?m. The composite compacts were obtained by spark
plasma sintering. Both, composite powders, and compacts were investigated by
X-ray diffraction (XRD), high temperature X-ray diffraction (HT-XRD),
scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy
(EDX).
