✦ Synopsis

A dynamic fatigue study was performed on. a Li20-AI203-SiO2 glass ceramic to assess its susceptibility to delayed failure and to compare the results with those from a previous study. Fracture mechanics techniques were used to analyse the results for the purpose of making lifetime predictions. The material strength and lifetime was seen to increase due to the removal of residual stress through grinding and polishing. Influence on time-to-failure is addressed for the case with and without residual stress present.

The effects of the melt casting and the sintering methods on the machinability and other characteristics of a SiO 2 -Al 2 O 3 -MgO-K 2 O-B 2 O 3 -F glass-ceramic composition were examined. The results show that the specimen prepared by the sintering method had better machinability and mechanical pro
