Showing papers on "Ferroelasticity published in 1987"
TL;DR: Polarized Raman spectra of single crystals of phenothiazine which undergoes a phase transition around 250 K and is ferroelastic in the low-temperature phase were measured in the lattice-vibrational region for temperatures ranging from 89 to 300 K as discussed by the authors.

TL;DR: In this paper, the existence of ferroelasticity in tetragonal zirconia was investigated and the reorientation of the domains by externally applied stress was proposed as a toughening mechanism.
Abstract: X-ray diffraction data are presented in support of the existence of ferroelasticity in tetragonal zirconia. Reorientation of ferroelastic domains by externally applied stress is proposed as a toughening mechanism. Toughening by this mechanism can occur in addition to transformation toughening and also explains high toughness of some zirconias which exhibit no transformation to the monoclinic form. Zirconia ceramics toughened by the ferroelastic mechanism have the potential to retain high toughness at elevated temperature unlike transformation toughening.
