Formidable increase of superplasticity of ceramics in presence of an electric field
2003 (English)In: Advanced Materials, ISSN 0935-9648, E-ISSN 1521-4095, Vol. 15, no 12, 1006-1009 p.Article in journal (Refereed) Published
The ductility of silicon nitride-based ceramics is dramatically enhanced in the presence of a pulsed electric field/current that induces movement of the charged species present in the grain boundary glassy/liquid phase, and thereby promotes grain sliding along the grain boundaries. The Figure shows an α-sialon component before (right) and after (left) deformation.
