Abstract

Macro- and microstrength (four point bending strength σB, critical stress intensity factor KIc, and load-independent microhardness L2VH) were determined on different glasses of the chalcogenide system Se-Ge-As. σB values lay between 10 and 25 Nmm-2, KIc values between 5.5 and 9.4 Nmm-3/2 and L2VH values between 700 and 1400 Nmm-2. The values on chalcogenide glasses are discussed with respect to other glass compositions.
