Abstract
Certain features of twinning reported recently in the literature for the Y-Ba-Cu-O superconductor are reinterpreted as being due to the presence of multiple disorientations in this ferroelastic material. The possibility of coherent and incoherent twin boundaries existing in the same crystal is pointed out. It is suggested that disorientations (and their local variations) could be providing an additional strain-relieving mechanism not incorporated so far in the spinodal-decomposition model of Khachaturyan et al.Keywords
