| Abstract: | The influences of Y-PSZ content on densification and mechanical properties of Y-PSZ containing A12O3 prepared with nanopowder have been investigated.It is shown that additing Y-PSZ to A12O3promotes densification of A12O3 and decreases sintering temperature.The Y-PSZ inclusions also significantly inhibite grain growth of A12O3 which resulted in the improvements in both hardness and toughness of Al2O3(Y-PSZ). |
