Abstract
The microstructures and creep properties of one experimental and two commercial LAS glass ceramics have been studied. The commercial materials creep at lower temperatures and exhibit more prominently non-linear creep (creep rate decreasing with time). Heat treatment causes grain growth and a redistribution of precipitate and leads to a reduction in creep rates in all materials.
