Eshelby twists have been microscopically observed at the tapered tips of alumina whiskers grown by the reaction Al2O(g)+2H2O(g)⇌2H2(g)+Al2O3(s).It has been found that the twist and associated screw dislocation can be removed by nonuniform bending occurring during breakage of the whisker from its base.
