Abstract

An integrated set of experimental techniques for mechanical and thermal testing of the Ti³Al/SCS-6 metal matrix composite is presented. Areas of discussion include gripping, specimen design, specimen heating, temperature measurement, and displacement measurement. The grip system was originally developed for use with ceramic composite materials and works well with the relatively brittle titanium-aluminide matrix composite used in this study. A modified version of an existing quartz lamp heating system allows temperature control at multiple points on the specimen. Results from baseline tension tests at various temperatures and post-thermal cycling tension tests are presented.
