Influence of elastic anisotropy on structural nanoscale textures

P Lloveras, T Castán, M Porta, A Planes, A Saxena - Physical review letters, 2008 - APS
We study the influence of elastic anisotropy on nanoscale precursor textures that exist in
some shape-memory alloys and show that tweed occurs in the limit of high elastic anisotropy …

Defect-induced incompatibility of elastic strains: dislocations within the Landau theory of martensitic phase transformations

R Gröger, T Lookman, A Saxena - Physical Review B—Condensed Matter and …, 2008 - APS
In dislocation-free martensites the components of the elastic strain tensor are constrained by
the Saint-Venant compatibility condition which guarantees continuity of the body during …

Strain pseudospins with power-law interactions: Glassy textures of a cooled coupled-map lattice

SR Shenoy, T Lookman - Physical Review B—Condensed Matter and …, 2008 - APS
We consider a spin-1 model of strain pseudospins S (r ⃗)= 0,±1 that arise from a triple-well
Landau free energy for a square/rectangle or “austenite-martensite” structural transformation …

Signature of martensite transformation on conductivity noise in thin films of NiTi shape memory alloys

A Ghosh, HS Vijaya, S Mohan - Applied Physics Letters, 2008 - pubs.aip.org
Slow time-dependent fluctuations, or noise, in the electrical resistance of dc magnetron
