Ginzburg-Landau modelling of precursor nanoscale textures in ferroelastic materials
(2012-11)
Article
Restricted access - publisher's policyA Ginzburg–Landau free-energy model is proposed to study spatially inhomogeneous states that often occur as precursors of ferroelastic/martensitic transitions. Disorder is included in the harmonic coefficient of the ... -
Glassy behavior in martensites: Interplay between elastic anisotropy and disorder in zero-field-cooling/field-cooling simulation experiments
(2009-08-17)
Article
Restricted access - publisher's policyWe study the combined effect of elastic anisotropy and disorder on the microstructure and thermodynamic behavior in alloys undergoing a martensitic transformation. Within a Ginzburg-Landau free-energy framework we find the ... -
Influence of elastic anisotropy on structural nanoscale textures
(2008-04-25)
Article
Restricted access - publisher's policyWe study the influence of elastic anisotropy on nanoscale precursor textures that exist in some shapememory alloys and show that tweed occurs in the limit of high elastic anisotropy while a nanocluster phase-separated state ... -
Intermittent dynamics in externally driven ferroelastics and strain glasses
(American Institute of Physics (AIP), 2018-09-28)
Article
Open Access -
Spatially correlated disorder in self-organized precursor magnetic nanostructures
(2007-08-20)
Article
Restricted access - publisher's policyWe study the scaling behavior of the characteristic length of precursor magnetic nanostructures above the Curie temperature with the correlation length of quenched-in disorder. We found that the modulation length of the ... -
Thermodynamics of stress-induced ferroelastic transitions: Influence of anisotropy and disorder
(2010-06-07)
Article
Restricted access - publisher's policyStress-induced stress-strain constitutive behavior has been studied in detail in ferroelastic martensites. It has been found that the weights of the long-range anisotropic interactions and of the disorder are important ...
