LAOS enhances the formation of plate-like nuclei and orients their normals in the gradient direction. An Arrhenius temperature dependence (with activation energy approximate to 226 kJ/mol) characterizes the relaxation of crystal orientation with annealing.</p>1 aSreenivas, K.1 aKumaraswamy, Guruswamy  uhttps://library.ncl.res.in/content/large-amplitude-oscillatory-shear-induces-crystal-chain-orientation-velocity-gradient-0
