Fabrication of Ni-Al System Intermetallic Compounds Used Reaction Sintering Using Hot-Pressing

Abstract

Reaction sintering using hot-press in vacuum, argon gas and atmosphere was carried out in order to increase the density of the Ni-Al system intermetallic compound. The density, microhardness and reactants of the compacts were examined and discussed. The results showed that high density Ni-Al system intermetallic compound can be obtained by reaction sintering using hot-press. The Ni-Al system intermetallic compound can be produced by reaction sintering using hot-press in argon gas and atmosphere.
