    Measurements of coarse control arm drop characteristics in the materials testing reactor HIFAR
    (Australian Atomic Energy Commission, 1983-02) Marshall, J; Blevins, RJ
    Measurements were made of the angular position/time characteristics of a coarse control arm in the AAEC's materials testing reactor HIFAR following a trip. The method of measurement is described and the results are presented. It is clear that all of the measured transients may be reasonably fitted by a single differential equation.

    Residual stress measurements by neutron diffraction in multi-bead welding
    (Elsevier, 2006-11-15) Paradowska, AM; Price, JWH; Ibrahim, R; Finlayson, TR; Blevins, RJ; Ripley, MI
    The neutron diffraction technique is used to investigate and compare the residual stress characteristics in fully restrained samples with different numbers of beads. The aim of the research was to characterize the residual stress distribution which arises in a welded component with increasing the number of passes or beads. The resolution of the measurements carried out in this work achieves a new level of detail and reveals significant features of the residual stress pattern in multi-bead welding. The findings have important consequences for the design of welding procedures, demonstrating the effects of placing new beads on prior welding. © 2006 Elsevier B.V.

    Residual stress measurements by neutron diffraction in welded steel structures
    (The Bragg Institute, Australian Nuclear Science and Technology Organisation, 2005-11-27) Paradowska, AM; Price, JWH; Finlayson, TR; Ibrahim, R; Blevins, RJ; Ripley, MI
    In this paper the neutron diffraction technique is used to investigate and compare the residual stress characteristics due to various restraints for a single bead and in fully restrained samples with different numbers of beads. The aim of the research was to characterize the residual stress distribution which arises in a welded component with increasing the number of passes. The care and resolution of the measurements carried out in this work achieves a new level of detail and reveals significant features of the residual stress pattern in multi-bead welding. The findings have important consequences for the design of welding procedures, and fitness-for-purpose assessments. © The Authors
