Summary: A lead-free piezoelectric ceramic based on (K,Na)NbO3 is textured using NaNbO3 seeds in the (001) direction, resulting in improved electromechanical coefficients at room temperature. The textured composition with 5 wt % NN template exhibits enhanced electromechanical coefficients and is used to fabricate a flexible piezoelectric energy harvester. The textured energy harvester outperforms the random ceramic-based harvester due to its higher figure-of-merit value.

Summary: The ferroelectric and piezoelectric properties of Sr2Nb2O7-La2Ti2O7 solid solution ceramics were studied. Substitution of La and Ti ions into the SNB lattice resulted in lattice distortion. Rietveld refinement parameters confirmed the solid solution of Sr2Nb2O7-La2Ti2O7. The addition of La3+ and Ti4+ ions weakened the intra-structural phase of SNB.

Summary: This study investigates the influence of different conductive buffer electrode layers on the electrical properties, fatigue behavior, and phase transition of epitaxial KNN-based ferroelectric films. The results demonstrate that the properties and fatigue resistance of the films are significantly influenced by the buffer electrode layers, with p-type electrodes showing superior performance compared to n-type electrodes. The temperature-dependent dielectric analysis reveals that all studied films exhibit relaxor ferroelectric behavior, with p-type electrode buffered films exhibiting higher phase transition temperatures.

Summary: An innovative strategy based on defect dipoles is proposed to achieve a giant piezoelectric strain coefficient in Li/Sr-doped (K0.5Na0.5)NbO3 lead-free piezoceramics. The enhanced strain performance is attributed to the optimized strain compatibility between the refined stripe domains and nanosized domains. Additionally, the material is able to recover from fatigue-induced strain depletion under the stimulation of bipolar electric fields, which can be explained by the rigid ion model.

Summary: The strain behavior of PMN-PT single crystals on different orientations was studied, revealing that the seemingly different strain behavior originated from the same mechanism, ruling out the contribution from polarization rotation. The experiment results suggested that the polarization vectors affecting the strain properties in PMN-PT are not restricted to a unique direction imposed by crystallographic symmetry.

Summary: The structural instability, relaxor ferroelectricity, and microwave dielectric properties of Sr(1-x)CexTi(1-2/3y)MgyO3 ceramic samples (sintered in 5%H2 and 95%N2 atmosphere) were systematically studied. The results show that the structural symmetry of the samples varies with different doping concentrations, and there is a frequency-dependent dielectric maxima and intrinsic ferroelectric nature. The sample with x=0.15 exhibits low microwave dielectric permittivity, good temperature stability of resonance frequency, and high Q-factor.

Summary: A Landau phenomenological approach is used to calculate the polarization, dipolar entropy, and free energy in ferroelectric and antiferroelectric materials, revealing that the inverse electrocaloric effect is caused by the antiparallel alignment of polarization with the applied electric field, leading to a decrease in free energy density and an increase in dipolar entropy.

Summary: The composition-temperature-electric field diagram and electrocaloric properties of BaTi1_xZrxO3 (BZT) were calculated. The adiabatic temperature change due to material polarization at critical end, tricritical, and phase convergence points was quantified. The largest temperature change occurred at the first-order paraelectric to ferroelectric transitions, while the greatest material polarization contribution was observed at the critical temperature. The maximum electrocaloric responsivity occurred at a field 1.25 times greater than the critical field. The enhanced temperature change near the convergence point was attributed to greater polarization change in the rhombohedral phase and a polar glasslike state that contributed to the dipolar configurational entropy.

Researchers have explored the use of graphene as a covering layer to achieve atomically flat surfaces.

Summary: Elemental powders of Al, Ti, Sc, and Zr are blended and processed via laser powder-bed fusion to create binary and ternary alloys. The microstructural analysis and mechanical testing show that the addition of Ti results in the formation of primary precipitates, while the addition of Sc and Zr leads to the formation of fine grain bands. The Al-0.25Ti-0.25Zr alloy exhibits comparable strain rates to Al-0.5Zr at low stresses, but significantly higher strain rates at higher stresses during compressive creep testing. Finite element modeling suggests that the connectivity of coarse and fine grain regions is a critical factor affecting the creep resistance of the alloys.

Summary: The limited slip systems of magnesium (Mg) and its alloys hinder their wide applications. By conducting tensile straining experiments, researchers discovered a rate-dependent transition in the dislocation mechanisms of Mg alloys. At high strain rates, glissile dislocations dominate, while easy-glide dislocations dominate at low strain rates. Abundant glissile dislocations do not necessarily improve ductility.

Summary: Inverse temperature dependences of the detwinning stress were observed in face-centered cubic deformation twins in Cu-8at.%Al alloy. The detwinning stress increased with temperature when the pi detwinning mode was involved, but decreased when the pi/3 mode was involved. The dual effect of temperature on the detwinning stress was due to the reduction of internal stresses pre-existing within the deformation twins. The complete reduction of internal stresses at about 530 degrees C led to the equivalence of the critical stresses of different detwinning modes and a decrease in the yield stress anisotropy of the twin/matrix structure.

Summary: The elastic-plastic transition in magnesium alloy Mg-4.5Zn exhibits bursts of deformation, which are characterized by sudden changes in grain orientation. These bursts occur in a coordinated manner among nearby grains, with the highest burst rate observed at the onset of full plasticity. The most significant burst events are associated with twinning, supported by the observation of twinned structures using electron microscopy. The bursts are often preceded and followed by a stasis in peak movement, indicating a certain "birth size" for twins upon formation and subsequent growth at a later stage.

Summary: A novel testing system for miniature specimens is designed to characterize the plastic response of materials for which conventional full-size specimens cannot be extracted. The system has an automated operation process, which reduces the damage to specimens caused by manual handling and improves the stability of the test results. The experiments show that the miniature specimens extracted from stainless steel and aluminum have high reproducibility, and the results are consistent with those of conventional-sized specimens. A correction procedure is provided to consider the influence of surface roughness and heat-affected zone caused by wire EDM.
