Notes:
High-density nickel-cobalt alloy-dispersed Al2O3 (Al2O3/Ni-Co alloy) composites were obtained via the hydrogen reduction and hot pressing of Al2O3, Ni(NO3)26H2O, and Co(NO3)26H2O powder mixtures. Microstructural investigations revealed that nanometer-sized alloy particles were dispersed homogeneously at the matrix grain boundaries, forming the intergranular-type nanocomposite. High strength (〉1 GPa) was registered for the Al2O3/10 wt% Ni-Co alloy composite. An inverse magnetostrictive response to applied stress was observed, because of the Ni-Co alloy dispersions, which indicates promise for incorporating new functions such as stress and fracture sensing into the structural ceramics without any loss of mechanical properties.
