Toward an Understanding of the Mechanical Mixed Alkali Effect in Glasses

摘要

The mechanical properties of mixed alkali glasses have been analyzed in order to determine their common features, including systematic variations with composition, and to define clearly the phenomena that must be explained. New assignments of the mechanical loss peaks are made, and approaches to developing a cooperative theory for the phenomena, especially the compositional variation of the peak temperatures and loss tangents, are presented and discussed.
