چکیده
Shrinkage behaviors during shrinkage rate-controlled flash (SCF) sintering were investigated for 8 mol% Y2O3–ZrO2 (8YSZ) when rates varied between 60 and 300 μm/min under alternating current fields of 50 Vrms/cm, 1200 mArms, 1000 Hz at a furnace temperature approximately 870°C. Volumetric power dissipation electrical conductivity shown to exhibit similar dependencies against linear shrinkages even if the changed. The 8YSZ polycrystals, with microstructure density, could be produced all SCF conditions used in this study, which was confirmed as characteristic feature sintering. Finally, polycrystals density 5.91–5.93 g/cm3 grain size 2.2–2.6 μm process period 15–65 min

Sintering Behavior of 0.8 mol%-CuO-Doped 3Y-TZP Ceramics
In recent years, 3 mol% yttria-stabilized tetragonal zirconia polycrystals (3Y-TZP) doped with copper oxide has obtained increasing interest due to its enhanced superplastisity and good potential in tribological applications. In this work, the effect of addition of small amounts (0.8 mol%) of copper oxide on the sintering behavior of 3Y-TZP was studied using a dilatometer and high-temperature X...
متن کاملReducing Power Dissipation in SRAM during Test
In this paper we analyze the power consumption of SRAM memories and demonstrate that the full functional pre-charge activity is not necessary during test because of the predictable addressing sequence. We exploit this observation in order to minimize power dissipation during test by eliminating the unnecessary power consumption associated with the pre-charge activity. This is achieved through a...
متن کاملMaster sintering curve for Gd-doped CeO2 solid electrolytes
The sintering behavior of gadolinia-doped ceria powders was studied by the master sintering curve (MSC). Dilatometric analyses of powders produced by a soft chemical method were performed to provide the experimental data set for the construction of the MSC. The assumed model provided good fittings of the MSC and the activation energy for the sintering of Ce1-xGdxO3-d, with x = 0, 0.05, 0.1, and...
متن کاملMuscle power attenuation by tendon during energy dissipation.
An important function of skeletal muscle is deceleration via active muscle fascicle lengthening, which dissipates movement energy. The mechanical interplay between muscle contraction and tendon elasticity is critical when muscles produce energy. However, the role of tendon elasticity during muscular energy dissipation remains unknown. We tested the hypothesis that tendon elasticity functions as...
متن کاملMinimizing Power Dissipation during Write Operation to Register Files
This paper presents a power reduction mechanism for the write operation in register files (RegFiles), which adds a conditional charge-sharing structure to the pair of complementary bit-lines in each column of the RegFile. Because the read and write ports for the RegFile are separately implemented, it is possible to avoid pre-charging the bit-line pair for consecutive writes. More precisely, whe...
