Abstract : Creep crack-opening displacement was measured at 732 C (1350 F) using an interference displacement gage and a minicomputer based analysis system to calculate compliance and provide realtime control and analysis. The system, based on a HeNe laser interferometer, was used to measure creep crack growth in IN-100, a nickel-based superalloy. (Author)
