Static and dynamic mechanical properties of alumina reinforced with sub-micron Ni particles

This paper reports on the investigation of the static and dynamic properties of an alumina ceramic and nickel alumina nanocomposite and how the ceramic fabrication method affects these properties. In this study, two fabrication methods were used to create the monolithic alumina and the nanocomposites: pressure filtration and slip casting. The static fracture tests followed the ASTM Three Point Bend test while the dynamic fracture tests were conducted using the One Point Impact Test. This study shows that the fabrication method can affect the flexural strength properties of the materials.
