SYNTHESIS OF Al-Y-Ni-Co COMPOSITES BY MECHANICAL ALLOYING AND CONSECUTIVE SPARK-PLASMA SINTERING

摘要

Al_(85)Y_8Ni_5Co_2 composites were synthesized by mechanical alloying of pure elements and consecutive spark-plasma sintering. X-ray diffraction, DSC measurements and ~(57)Fe Moessbauer spectroscopy (due to a small amount of Fe isotope added to the initial mixture) were used to obtain information about synthesis process as well as structure and properties of the composites.
