Residual stresses and magnetic properties of alumina–nickel nanocomposites

Nanocomposites were produced by infiltration of alumina preforms with a nickel-nitrate solution, followed by reduction and sintering. Multiple infiltration and reduction steps resulted in nanocomposites with varying Ni particle concentrations. The strain in the nickel particles was evaluated from X-...

Description
Summary:Nanocomposites were produced by infiltration of alumina preforms with a nickel-nitrate solution, followed by reduction and sintering. Multiple infiltration and reduction steps resulted in nanocomposites with varying Ni particle concentrations. The strain in the nickel particles was evaluated from X-ray diffraction, and correlated with the magnetic properties of the nanocomposites.
