ANSTO Publications Online

Welcome to the ANSTO Institutional Repository known as APO.

The APO database has been migrated to version 8.3. The functionality has changed, but the content remains the same.

ANSTO Publications Online is a digital repository for publications authored by ANSTO staff since 2007. The Repository also contains ANSTO Publications, such as Reports and Promotional Material. ANSTO publications prior to 2007 continue to be added progressively as they are in identified in the library. ANSTO authors can be identified under a single point of entry within the database. The citation is as it appears on the item, even with incorrect spelling, which is marked by (sic) or with additional notes in the description field.

If items are only held in hardcopy in the ANSTO Library collection notes are being added to the item to identify the Dewey Call number: as DDC followed by the number.

APO will be integrated with the Research Information System which is currently being implemented at ANSTO. The flow on effect will be permission to publish, which should allow pre-prints and post prints to be added where content is locked behind a paywall. To determine which version can be added to APO authors should check Sherpa Romeo. ANSTO research is increasingly being published in open access due mainly to the Council of Australian University Librarians read and publish agreements, and some direct publisher agreements with our organisation. In addition, open access items are also facilitated through collaboration and open access agreements with overseas authors such as Plan S.

ANSTO authors are encouraged to use a CC-BY licence when publishing open access. Statistics have been returned to the database and are now visible to users to show item usage and where this usage is coming from.

    Residual stresses in WC-Co coatings in as-sprayed and surface-ground conditions
    (ASM International, 2015-05-11) Luzin, V; Valarezo, A; Vackel, A; Sampath, S
    The mechanical integrity of WC-Co coatings is critical for their performance in wear, corrosion, and impact resistance applications. Residual stress, with its role in development of cracking, micro-cracking, and delamination, is another integral part of the mechanical characterization of the coated systems. In the given study, the residual stress of the WC-Co coatings on steel and stainless steel substrates was examined in two conditions, after deposition and after subsequent surface grinding. Several experimental techniques, including bi-layer curvature, X-ray diffraction, and neutron diffraction, were used to assess residual stress in the coatings and to enable comparison between the methods. Residual stresses induced by deposition are mostly due to rapid particle quenching and solidification upon impact, as well as any cold working induced by high velocity particle impact, but for the WC ceramic particles both effects are insignificant and result in small deposition stress. Thermal mismatch between materials of coating and substrate is the major source of stress and scale accordingly to the CTE of the substrate and coating materials and deposition temperature. It was demonstrated that the grinding applied to surface does not modify the as-sprayed residual stresses in the coatings significantly therefore assuming absence of microcracking that could have potentially affect the residual stresses. ©Copyright 2025 ASM International

    Creep performance of welded structures at high temperatures
    (Wit Press, 1998-12-01) Law, M; Payten, W
    The operation of high temperature plant is often terminated by localised creep damage of welded joints. Despite its economic significance. Weld performance under creep is poorly understood. The creep life of welds cannot be directly predicted by the properties of individual parts of the weld. Numerical modelling of creep processes in welded joints provides a method of predicting creep performance and life.

    The effects of temperature variation on the creep behaviour of pressure vessels using theta projection data
    (2001-09-19) Law, M; Payten, W; Snowden, K
    The effect of thermal gradients on thick walled pressure vessels can be significant. Where thermal gradients occur, thermally induced stresses [1] will exist in addition to the pressure stresses. The creep response of the wall depends on the local stress, temperature, and previous creep history. The combination of the altered initial stress state and the altered creep response may lead to differing final stress states through time and a reduced creep life to that calculated for vessels without temperature variation using a constant secondary creep rate law. ©Civil-Comp Limited 2023 - terms & conditions

    Physical, chemical and optical properties of Australian desert dust aerosols
    (Department of the Environment and Water Resources, 2007-09-09) Radhi, M; Box, MA; Box, GP; Mitchell, RM; Cohen, DD; Stelcer, E; Keywood, MD; French, D
    Atmospheric aerosols interact with incoming solar radiation, and to a lesser extent with outgoing longwave radiation, in a number of ways. Aerosols scatter incoming sunlight, with a fraction being scattered back to space. This process is known as the direct aerosol effect, and is partially offsetting the warming from increases in greenhouse gases. Some aerosols, depending on their refractive index, and hence on their chemistry, absorb sunlight. This can result in not only a planetary warming (rather than a cooling), but also changes in the atmospheric temperature profile, and hence vertical stability, with potential hydrological consequences. Desert dust (mineral aerosol) is one of the major natural aerosol types, as recognized by the IPCC. However, at the time of the Third Assessment it was not possible to even be sure of the sign of desert dust forcing - i.e. warming or cooling. This is because mineral aerosols are mildly absorbing, a reflection of their variable iron content. Unlike many Northern Hemisphere deserts, which are yellow, Australian deserts are predominantly red, indicative of a different mineralogy. We have established a field station at Birdsville, in SW Queensland. Among other instrumentation, we operated aerosol samplers during a field campaign in November 2006. Using a twelve-stage MOUDI sampler, we collected size-resolved aerosols and subjected them to ion-beam analysis to determine the elemental composition. Samples were also collected in a single stage LowVol sampler. These samples were also sent for IBA as a cross check, but also for electron microscopy to study both shape and size, and the mineralogy of individual particles. Preliminary results of these analyses are presented. After further analysis we plan to construct size-resolved refractive indices, to determine the key optical parameters of Australian desert dust, and hence its role in climate forcing.
