“…This means that the lattice strain in the tetragonal phase in ZrO 2 increased after SP, which is one of the reasons that large compressive residual stress could be introduced into the near-surface of the ZrO 2 specimens. This phenomenon was considered to be the switching of lattice constants (a and c in Figure 10) due to compressive contact stress during SP, likely causing toughening in ZrO 2 due to ferroelastic domain switching [16].…”

“…Tetragonal-to-monoclinic phase transformation [14] [15] and ferroelastic domain switching [16] [17] are well-known mechanisms for toughening of ZrO 2 . Mc Meeking et al [15] presented that tetragonal-to-monoclinic phase transformation, for one, prevents crack propagation at the crack tip because of the crack closure effect.…”

In this paper, the sliding contact fatigue wear performance of shot-peened zirconia-silicon carbide composite (ZrO 2 /SiC) plates in contact with silicon nitride balls under compressive residual stress in dry conditions was investigated in order to improve the wear resistance of ZrO 2 /SiC friction parts. The wear resistance of ZrO 2 /SiC plates after shot peening was higher than that of plates not treated with shot peening in sliding wear testing under Hertziancontact. Due to fine Zirconia particle shot peening, the tetragonal phase crystal structure in ZrO 2 in the near-surface of ZrO 2 /SiC plates was changed, and 1100 MPa compressive residual stress could be introduced into the near-surface layer of ZrO 2 /SiC plates. The compressive residual stress was determined to be the main factor in the improvement of the sliding wear resistance of ZrO 2 /SiC plates.

“…This anelastic phenomenon appears even at extremely low stress level (Ͻ100 MPa) and produces time-dependent and recoverable strain. 9,10) Therefore, such a unique behavior cannot be explained by conventional mechanism, for example, stress-induced phase transformation, [19][20][21] ferroelastic domain switching, [22][23][24][25] microcracking [26][27][28] and so on. It is well known that the large amount of oxygen vacancy is introduced in matrix of the Y 2 O 3 -ZrO 2 and MgO-ZrO 2 systems in order to keep electrical balance and, on the other hand, the CeO 2 -ZrO 2 system seems to have few vacancies.…”

The tensile strength of four kinds of zirconia ceramics (two kinds of Y-TZP with different grain sizes, Mg-PSZ and Ce-TZP) has been investigated for a wide range of strain rates (3ϫ10 Ϫ9 -1.0ϫ10 Ϫ1 s Ϫ1) in both air and vacuum. The obviously unique strain rate dependence was observed in Y-TZPs and Mg-PSZ, which have anelastic properties. On the other hand, such strain rate dependence was not observed over the whole range of strain rates for Ce-TZP, which does not exhibit anelasticity. For all of the samples investigated, there was no significant difference between both values of tensile fracture strength in air and vacuum. It was found that a decrease in strength with decreasing strain rate should not be associated with the static fatigue growth of microcracks nucleated during loading. It was concluded that the extent of the occurrence and the exhaustion of anelasticity predominantly controls the tensile strength of zirconia ceramics.KEY WORDS: anelasticity; ADOV; ceramics; fatigue; fracture and fracture toughness. materials are degraded in hydrogen environment. 11,12) However, the extent of the strength degradation or static fatigue in hydrogen is lower than that in air, as reported in alumina and zirconia ceramics.11,12) Therefore, it is much more important to examine the mechanical behavior in air from the view point of clarifying the environmental effect in the ceramic materials loaded. There are quite a few reports that discuss the strain rate effect in zirconia ceramics. 4,6,7) Moreover, these studies have been carried out under compression testing, with the discussion focusing on tensile crack growth. [2][3][4][5][6][7] In this study, we conducted dynamic tensile testing over a wide range of strain rates for four kinds of zirconia ceramics, which have different mechanical properties, transformability, anelastic properties 9,10,13-18) and so on. Dynamic fracture testing was also carried out in vacuum in order to verify the true effect of subcritical microcrack growth on the strain rate dependence of tensile fracture strength. Possible Mechanism of Anelasticity in Zirconia CeramicsIn our recent work, 17,18) we have investigated anelastic behavior in some kinds of zirconia ceramics. Figure 2 shows the anelastic behavior in four kinds of materials (Y-TZP, Y-FSZ, Mg-PSZ and Ce-TZP) at 100 MPa and loadholding time of 10 h.18) This figure indicates that anelastic strain is produced in the Y 2 O 3 -ZrO 2 and MgO-ZrO 2 systems, but almost not in the CeO 2 -ZrO 2 system, irrespectively of the kind of crystallographic phase. This anelastic phenomenon appears even at extremely low stress level (Ͻ100 MPa) and produces time-dependent and recoverable strain.9,10) Therefore, such a unique behavior cannot be explained by conventional mechanism, for example, stress-induced phase transformation, [19][20][21] ferroelastic domain switching, [22][23][24][25] microcracking [26][27][28] and so on.
