Electric Current Activation of Sintering: A Review of the Pulsed Electric Current Sintering Process
Munir, Zuhair A.; Quach, Dat V.; Ohyanagi, Manshi

The phenomenal increase during the past decade in research utilizing pulsed electric current to activate sintering is attributed generally to the intrinsic advantages of the method relative to conventional sintering methods and to the observations of the enhanced properties of materials consolidated by this method. This review focuses on the fundamental aspects of the process, discussing the reported observations and simulation studies in terms of the basic aspects of the process and identifying the intrinsic benefits of the use of the parameters of current (and pulsing), pressure, and heating rate.

Piezoelectric Materials for High Temperature Sensors
Zhang, Shujun; Yu, Fapeng

Piezoelectric materials that can function at high temperatures without failure are desired for structural health monitoring and/or nondestructive evaluation of the next generation turbines, more efficient jet engines, steam, and nuclear/electrical power plants. The operational temperature range of smart transducers is limited by the sensing capability of the piezoelectric material at elevated temperatures, increased conductivity and mechanical attenuation, variation of the piezoelectric properties with temperature.

Lead-Free Relaxor Ferroelectrics
Shvartsman, Vladimir V.; Lupascu, Doru C.

Feature size is a natural determinant of material properties. Its design offers the technological perspectives for material improvement. Grain size, crystallite size, domain width, and structural defects of different nature constitute the classical design elements. Common ferroelectric ceramics contain micrometer grain sizes and submicrometer domain widths. Domain wall mobility is a major contribution to their macroscopic material properties providing approximately half of the macroscopic output in optimized materials. The extension into the dynamic nanoworld is provided by relaxor ferroelectrics. Ionic and nanoscale field disorders form the base to a state with natural nanometer-size polar structures even in bulk materials. Read the entire abstract.

Large Plastic Deformation in High-Capacity Lithium-Ion Batteries Caused by Charge and Discharge
Zhao, Kejie; Pharr, Matt; Cai, Shengqiang; et al.

Evidence has accumulated recently that a high-capacity electrode of a lithium-ion battery may not recover its initial shape after a cycle of charge and discharge. Such a plastic behavior is studied here by formulating a theory that couples large amounts of lithiation and deformation. The homogeneous lithiation and deformation in a small element of an electrode under stresses is analyzed within nonequilibrium thermodynamics, permitting a discussion of equilibrium with respect to some processes, but not others. The element is assumed to undergo plastic deformation when the stresses reach a yield condition. Read the entire abstract.

Origins of Electro-Mechanical Coupling in Polycrystalline Ferroelectrics During Subcoercive Electrical Loading
Pramanick, Abhijit; Damjanovic, Dragan; Daniels, John E.; et al.

The electromechanical coupling in ferroelectric materials is controlled by several coexisting structural phenomena which can include piezoelectric lattice strain, 180° and non-180° domain wall motion, and interphase boundary motion. The structural mechanisms that contribute to electromechanical coupling have not been readily measured in the past, particularly under the low-to-medium driving electric field amplitudes at which many piezoelectric materials are used. In this feature, results from in situ, high-energy, and time-resolved X-ray diffraction experiments are interpreted together with macroscopic piezoelectric coefficient measurements in order to better understand the contribution of these mechanisms to the electromechanical coupling of polycrystalline ferroelectric materials.

Influence of Externally Imposed and Internally Generated Electrical Fields on Grain Growth, Diffusional Creep, Sintering and Related Phenomena in Ceramics
Raj, Rishi; Cologna, Marco; Francis, John S. C.

Microwaves and spark plasma sintering (SPS) enhance sinterability. Simple electrical fields, applied by means of a pair of electrodes to bare specimens, have been shown to accelerate the rate of superplastic deformation, reduce the time and temperature for sintering, and to retard the rate of grain growth. By inference, the influence of electrical and electromagnetic fields on grain boundary energetics and kinetics is unmistakable. Often, in ceramics, grain boundaries are themselves endowed with space charge that can couple with externally applied fields. The frequency dependence of this coupling ranging from zero frequency to microwave frequencies is discussed. Read the entire abstract.

The Antiferroelectric <-> Ferroelectric Phase Transition in Lead-Containing and Lead-Free Perovskite Ceramics
Tan, Xiaoli; Ma, Cheng; Frederick, Joshua; et al.

A comprehensive review on the latest development of the antiferroelectric ferroelectric phase transition is presented. The abrupt volume expansion and sudden development of polarization at the phase transition has been extensively investigated in PbZrO3-based perovskite ceramics. New research developments in these compositions, including the incommensurate domain structure, the auxetic behavior under electric fields in the induced ferroelectric phase, the ferroelastic behavior of the multicell cubic phase, the impact of radial compression, the unexpected electric field-induced ferroelectric-to-antiferroelectric transition, and the phase transition mechanical toughening effect have been summarized.

Remarkably Strong Piezoelectricity of Lead-Free (K0.45Na0.55)(0.98)Li-0.02(Nb0.77Ta0.18Sb0.05)O-3 Ceramic
Gao, Yong; Zhang, Jialiang; Qing, Yalin; et al.

Various lead-free (KxNa1−x)0.98Li0.02(Nb0.82−yTa0.18Sby)O3 ceramics with x=0.50, y=0.00–0.07 or x=0.40–0.60, y=0.05 were prepared by the conventional solid-state reaction method. Systematic investigation on the microstructures, crystalline structures, and dielectric and piezoelectric properties was carried out. Remarkably strong piezoelectricity has been achieved in (K0.45Na0.55)0.98Li0.02(Nb0.77Ta0.18Sb0.05)O3 ceramic, which shows the excellent piezoelectric properties of d33=413 pC/N, d31=−153 pC/N, kp=0.50, and k33=0.62.

HF-Based Etching Processes for Improving Laser Damage Resistance of Fused Silica Optical Surfaces
Suratwala, Tayyab I.; Miller, Phil E.; Bude, Jeffery D.; et al.

The effect of various HF-based etching processes on the laser damage resistance of scratched fused silica surfaces has been investigated. Conventionally polished and subsequently scratched fused silica plates were treated by submerging in various HF-based etchants (HF or NH4F:HF at various ratios and concentrations) under different process conditions (e.g., agitation frequencies, etch times, rinse conditions, and environmental cleanliness). Subsequently, the laser damage resistance (at 351 or 355 nm) of the treated surface was measured. Read the entire abstract.

Relaxor Characteristics of Morphotropic Phase Boundary (Bi1/2Na1/2)TiO3-(Bi1/2K1/2)TiO3 Modified with Bi(Zn1/2Ti1/2)O3
Dittmer, Robert; Jo, Wook; Daniels, John; et al.

Morphotropic phase boundary (Bi1/2Na1/2)TiO3–(Bi1/2K1/2)TiO3 (BNT–BKT), was modified with increasing additions of Bi(Zn1/2Ti1/2)O3 (BZT). Microstructure, electric-field-induced strain and polarization, dielectric permittivity, and temperature-dependent piezoelectric coefficient were investigated and compared with crystal structure measured in situ as a function of applied electric field. Furthermore, permittivity and piezoelectric coefficient were characterized as a function of electric field. Read the entire abstract.
