Abstract

This paper examines the α-ZrO2 ↔ β-ZrO2 polymorphic transformation in 75 wt % Al2O3 + 25 wt % ZrO2 alloys solidified under nonequilibrium conditions and then heat-treated under various conditions. The strength of the alloys is shown to be more sensitive to β-ZrO2 content than to the size of their microstructural constituents.
