A relatively large bipolar strain of 0.23 % was recently reported in 3 % Sn4+ doped (BaTi0.8Zr0.2)O3-x (Ba0.7Ca0.3)TiO3 (BZT-xBCT) ceramics under a field of 20 kV/cm. This strain is 53 % higher than that in BZT-50BCT (0.15 % at 20 kV/cm). To systemat

Traditional strategies for improving piezoelectric properties have focused on phase boundary engineering through complex chemical alloying and phase control. Although they have been successfully employed in bulk materials, they have not been effectiv

Room‐temperature magnetoelectric (ME) coupling is developed in artificial multilayers and nanocomposites composed of magnetostrictive and electrostrictive materials. While the coupling mechanisms and strengths in multilayers are widely studied, the

Experimental search for high-temperature ferroelectric perovskites is a challenging task due to the vast chemical space and lack of predictive guidelines. Here, we demonstrate a two-step machine learning approach to guide experiments in search of xBi

The search for high piezoelectric and electromechanical properties near morphotropic phase boundaries (MPB) in lead-free ceramics has attracted considerable interest. The MPB can be obtained in the composition-temperature phase diagram by combining s

A three dimensional (3D) elastoplastic phase-field model is developed for modeling the hydrostatic pressure-induced alpha – omega phase transformation and the reverse phase transformation, i.e. omega – alpha, in zirconium (Zr). Plastic deformatio

Atomic simulations provide an effective means to understand the underlying physics of structural phase transformations. However, this remains a challenge for certain allotropic metals due to the failure of classical interatomic potentials to represen

A three-dimensional elastoplastic phase-field model is developed, using the finite element method (FEM), for modeling the athermal beta to omega phase transformation in Zr–Nb alloys by including plastic deformation and strain hardening of the mater

An open question in the kinetics of martensitic transformation is the microscopic mechanism responsible for the evolution of a new phase. We have analyzed data from shocked recovered samples that monitor the volume fraction of the ω phase in α-Zr a

We investigate shock-induced phase transformations in titanium (α-Ti) single crystals induced by shock loading along the [0 0 0 1], [ 1 0 1 ¯ 0 ] and [ 1 2 1 ¯ 0 ] directions using molecular dynamics simulations. We find a significant dependence o
