Abstract

NixCo1−xO/ZrO2(CaO) directionally solidified eutectics (DSEs) form a ductile metallic interphase after they are chemically reduced at high temperatures. Vickers indentation tests have previously shown a significant change in the crack propagation behavior of the reduced composites due to plastic deformation and strain energy absorption mechanisms operating in the system after reduction. This paper focuses on structural and chemical characterization of NixCo1−xO/ZrO2(CaO) DSEs after reduction. Analytical transmission electron microscopy techniques such as energy dispersive x-ray spectroscopy (EDXS) and electron energy loss spectroscopy (EELS) show elimination of oxygen and formation of nanoscale Ni(Co) solid.
