Abstract
An automated system for crack growth studies under thermal-mechanical loading conditions utilizing a compact tension (CT) specimen has been developed. Since the materials to be tested are for high temperature machinery, they are of high cost and low availability, making the CT testing capability advantageous. The system described uses quartz lamps and a multiple-zone control system to accurately control the specimen temperature according to a predetermined profile. A cyclic mechanical loading can be applied along with cyclic temperature profile in a prescribed manner. Test results are discussed for fatigue crack growth behavior in a titanium aluminide intermetallic. 7 references.
