Summary:	Title screen The objective of this work was to study two-step sintering as a means of controlling the microstructure of coarse Al2O3 matrix composites containing submicrometric and nanometric inclusions of ZrO2 ranging from 0–30 wt. % by weight based on commercially available powders and evaluate its hydrothermal degradation as function of a water vapour pressure and its mechanical properties. The results showed that two-step sintering allowed a more efficient microstructural control than single-step sintering, resulting in good mechanical properties. The highest flexural strength was achieved for ZTA samples sintered in two-stage sintering conditions TSS2 with T1=1560 °C for 3 h, T2=1460 °C for 8 h. The studied composites showed good resistance to hydrothermal degradation compared to composites sintered in single step sintering conditions Режим доступа: по договору с организацией-держателем ресурса
