Sessile dissociation in the stoichiometric spinel MgAl2O4
Journal de Physique, 1979 Dislocations in spinel, MgO. nAl2O3, are dissociated out of their glide planes and precise determinations of the dissociation planes by stereographic analysis are reported. It is shown that for stoichiometric spinel (n = 1), the numerous, long and straight, edge dislocations left by a small strain on { 110 } glide planes, are dissociated in the { 110 }
