Phase field simulations of coupled phase transformations in ferroelastic-ferroelastic nanocomposites
Mathieu Bouville, Rajeev Ahluwalia
We use phase field simulations to study composites made of two different ferroelastics (e.g., two types of martensite). The deformation of one material due to a phase transformatio…
Microstructure and mechanical properties of constrained shape-memory alloy nanograins and nanowires
Mathieu Bouville, Rajeev Ahluwalia
We use the phase-field method to study the martensitic transformation at the nanoscale. For nanosystems such as nanowires and nanograins embedded in a stiff matrix, the geometric c…
Size Effects in Ferroelectric Thin Films: The Role of 180 degree domains
Rajeev Ahluwalia, David J. Srolovitz
The depolarization fields set up to due to uncompensated surface charges in a ferroelectric thin film can suppress the ferroelectric phase below a critical size. Recent experiments…
Effect of lattice mismatch-induced strains on coupled diffusive and displacive phase transformations
Mathieu Bouville, Rajeev Ahluwalia
Materials which can undergo slow diffusive transformations as well as fast displacive transformations are studied using the phase-field method. The model captures the essential fea…
Interplay between diffusive and displacive phase transformations: TTT diagrams and microstructures
Mathieu Bouville, Rajeev Ahluwalia
Materials which can undergo extremely fast displacive transformations as well as very slow diffusive transformations are studied using a Ginzburg-Landau framework to understand the…
Domain Size Dependence of Piezoelectric Properties of Ferroelectrics
Rajeev Ahluwalia, Turab Lookman, Avadh Saxena +1
The domain size dependence of piezoelectric properties of ferroelectrics is investigated using a continuum Ginzburg-Landau model that incorporates the long-range elastic and electr…
