DOI: 10.1016/j.ceramint.2019.09.068
Abstract: Abstract Fracture toughness, bending strength, Young's modulus, hardness and subcritical crack growth were determined for six different alumina/zirconia composites. The bending strength was modelled using Weibull distribution. The fracture toughness, bending strength and resistance to… read more here.

DOI: 10.1016/j.jeurceramsoc.2020.06.044
Abstract: Abstract Laminates with alternating layers are well known from nature. The strongly bonded alumina/zirconia (Al2O3/ZrO2) layers can combine high fracture resistance with high strength and stiffness when properly tailored. The presence of compressive residual stresses… read more here.

DOI: 10.3390/nano7120419
Abstract: In this paper, an alumina-zirconia (Al2O3-ZrO2) nanolaminate dielectric was fabricated by spin-coating and the performance was investigated. It was found that the properties of the dielectric can be adjusted by changing the content of Al2O3/ZrO2… read more here.
