Abstract

X-ray diffraction (XRD) utilizing copper K-alpha radiation and the single exposure technique (SET) was used for residual stress measurement on two different thermal treatments of Al-300 alumina rods. The measurements were performed in the axial and tangential directions on forty halves of twenty broken rods. The twenty rods were intially annealed for 8 hours at 1000°C; then ten were slow cooled and ten were equilibrated at 1450°C then force-air quenched. A fine mesh sapphire (alumina) powder was used as a zero stress standard for the determination of calibration validity of the position sensitive scintillation detector based (PSSD) stress measuring instrument used for this study. This instrument was developed at the Materials Research Laboratory of The Pennsylvania State University.
