Ferroelectric (FE) materials, which typically adopt the perovskite structure with non-centrosymmetry and exhibit spontaneous polarization, are promising for applications in memory, electromechanical energy storage devices. However, these advanced suffer from intrinsic limitations of FEs, including poor complementary metal oxide semiconductor (CMOS) compatibility environmental issues associated ...

Polyurea (PU) is a versatile high strain rate elastomeric polymer that has attracted significant interest due to its utility as blast and ballistic resistant coating. Predictive design of PU materials, particularly with focus on structure, complicated by the occurrence both pressure effects in response impact. To help elucidate behavior under such conditions, we sought characterize microstructu...

In this study, a novel unifi ed framework for the study of both microstructural evolution and the mechanical property quantifi cation is proposed. The multistate Potts model is used to simulate the microstructural evolution, whereas a volume-compensated particle method (VCPM) is used for the mechanical property quantifi cation of the steady state microstructure. The VCPM proposed by Chen and co...

A numerical method for the calculation of the electrical conductivity of porous ceramics for gas sensing applications is developed, which takes into account detailed microstructural features by mapping a mesoscopic irregular resistor network onto the microstructure. The overall conductance of the ceramic sample is obtained by solving the Kirchhoff equations for the irregular network using an ef...

The consolidation of fiber-reinforced titanium matrix composite (TMC) monotapes produced by spray deposition is an important step in the manufacture of TMC components. The performance of this class of composites is controlled by fiber-matrix properties and by the composite’s relative density, fiber microbending stress/fracture and by the interfacial reaction layer thickness at the fiber-matrix ...

Nanocrystalline Al–Mg dendrites were fabricated through galvanostatic electrodeposition. Initially feather-like morphology was formed exhibiting morphological evolution to smooth globules at its tips. With eventual deposition, rough globules formed over the smooth ones. The feather-like and smooth globules possessed supersaturated face centered cubic (fcc)–Al(Mg) phase with ~7 and ~20 at.% Mg r...

The present study demonstrates the evolution of eutectic microstructure in arc-melted (Zr0.76Fe0.24)100-xNbx (0 ≤ x ≤ 10 atom %) composites containing α-Zr//FeZr₂ nano-lamellae phases along with pro-eutectic Zr-rich intermetallic phase. The effects of Nb addition on the microstructural evolution and mechanical properties under compression, bulk hardness, elastic modulus, and indentation fractur...
