Moreover, the anharmonic nature of lattice vibrations in crystals plays an essential role in determining the lattice dynamics in the vicinity of structural phase transitions...5 p.application/pdfeng(c) The American Physical Society, 1999Matèria condensadaPropietats de la matèriaAliatgesTransformacions martensítiquesCondensed matterProperties of matterAlloysMartensitic transformationsinfo:eu-repo/semantics/article147492info:eu-repo/semantics/openAccess
