Nickel Aluminide (Ni3Al) Fabricated By Reactive Infiltration
Published online by Cambridge University Press: 22 February 2011
Abstract
Nickel aluminide Ni3Al in single phase form, with grain size ∼ 10 μm, porosity ∼ 5%, tensile strength 425 MPa, modulus 92 GPa and ductility 9.5% at room temperature, was fabricated by reactive infiltration at 800˚C of liquid aluminum into a porous preform containing 78 vol.% nickel and made by sintering 3–7 μm size nickel particles.
