X-ray elastic constants and residual surface stress state in glass ceramic
Röntgen-Elastizitätskonstanten und Restoberflächenspannungszustand in Glaskeramik
In a ß-Lithium-Aluminium-Silicon-Oxide glass ceramic X-ray stress measurements were performed. The cristalline phase investigated is ß-Eukryptite. The X-ray elastic constants were deterined at (118) - lattice planes using CrK alpha radiation. The surface stress state is determined as a function of depth below surface.
