An Optical Microscope was used to examine pit morphology and to measure pit depths. Cross-section microstructure and chemical composition of pits were investigated by means of Scanning Electron Microscopy and Energy Dispersive Spectrometry. Five deepest pits were measured on each face of a sextuplicate set of coupons. The pit depth data was analysed using extreme value statistics. Results show that the depth of the deepest pits progressed in a ‘step-wise’ manner. Pitting severity and the maximum pit depth increased with the depth of immersion. The results support previous findings indicating changes in corrosion mechanism with time. Similar to the corrosion of steels, this is considered to result from the build-up of corrosion products. The reason for this is discussed and further work is outlined.]]> Wed 11 Apr 2018 14:10:08 AEST ]]> Effect of microstructure in relation to heat affected zone (HAZ) corrosion of mild steel welds in marine environments https://novaprd-lb.newcastle.edu.au/vital/access/ /manager/Repository/uon:28669 Wed 11 Apr 2018 13:31:59 AEST ]]> Effect of high temperature on mineralogy, microstructure, shear stiffness and tensile strength of two Australian mudstones https://novaprd-lb.newcastle.edu.au/vital/access/ /manager/Repository/uon:26573 Wed 11 Apr 2018 12:42:36 AEST ]]> Environmental salinity and bitumen-sealed unbound granular road pavements https://novaprd-lb.newcastle.edu.au/vital/access/ /manager/Repository/uon:21907 Wed 11 Apr 2018 12:08:26 AEST ]]> Long-term marine corrosion of welds on steel piling https://novaprd-lb.newcastle.edu.au/vital/access/ /manager/Repository/uon:12195 Wed 11 Apr 2018 11:18:12 AEST ]]> Microstructural insight into the hysteretic water retention behavior of intact Mile expansive clay https://novaprd-lb.newcastle.edu.au/vital/access/ /manager/Repository/uon:54680 Wed 10 Jul 2024 11:52:44 AEST ]]> Shear strength and microstructure of polydisperse packings: the effect of size span and shape of particle size distribution https://novaprd-lb.newcastle.edu.au/vital/access/ /manager/Repository/uon:31949 Wed 08 Jul 2020 12:31:16 AEST ]]> Properties of self-compacting concrete with recycled concrete aggregates https://novaprd-lb.newcastle.edu.au/vital/access/ /manager/Repository/uon:41528 Wed 07 Feb 2024 17:59:39 AEDT ]]> Long-term marine immersion corrosion field trials of simulated steel weld HAZ https://novaprd-lb.newcastle.edu.au/vital/access/ /manager/Repository/uon:33843 Wed 04 Sep 2019 12:17:38 AEST ]]> Effect of graphene oxide (GO) on the morphology and microstructure of cement hydration products https://novaprd-lb.newcastle.edu.au/vital/access/ /manager/Repository/uon:31128 Tue 28 Jan 2020 16:23:50 AEDT ]]> Influence of Mechanical Screened Recycled Coarse Aggregates on Properties of Self-Compacting Concrete https://novaprd-lb.newcastle.edu.au/vital/access/ /manager/Repository/uon:52700 Tue 14 Nov 2023 13:02:37 AEDT ]]> An experimental investigation of unsaturated clay: volume change and microstructural considerations https://novaprd-lb.newcastle.edu.au/vital/access/ /manager/Repository/uon:22576 Tue 11 Dec 2018 14:59:52 AEDT ]]> Deformation of polycrystalline D2O ice: its sensitivity to temperature and strain-rate as an analogue for terrestrial ice https://novaprd-lb.newcastle.edu.au/vital/access/ /manager/Repository/uon:39109 2O) was deformed over a range of high-temperatures (−20 to −1 °C; 0.92–0.99Tm) during in situ neutron diffraction texture and grain-size analysis. This allowed for a continuous monitoring of the evolution of rheology, texture, grain-numbers and the type of microstructures, which are compared to those encountered in basal sections of ice-sheets. We quantify the textural evolution with >i>J-index changes as a function of strain-rate and temperature. Three sets of unconfined samples were deformed at displacement rates of 1 x 10-5s−1 (fast) 2.5 x 10-6 s−1 (medium) and 6 x 10-7 s−1 (slow). Dislocation creep is proposed as the main deformation mechanism with sub-grain rotation more significant at lower temperatures (0.92Tm) and/or higher strain-rates. At higher-temperatures (0.99Tm) and/or lower strain-rates dynamic recrystallization is dominated by grain boundary migration, typified by grains with highly curved or lobate grain boundaries, and leading to rheological softening of the ice. From initially randomly oriented [c]-axes, a texture comprising 30–35° cones parallel to the compression axis develops, which is comparable to textures observed in the upper levels of polar ice-sheets. There is also a strain-rate dependence on the development of normalized [c]-axis intensities, which is in competition with strain magnitude and temperature. At lower temperatures (≤10 °C), small increments of strain or slower strain-rates, the cone-angle and textural strength decrease with a dominant textural component parallel to the compression axis. This may be an explanation for the vertical [c]-axis concentrations observed in polar ice cores.]]> Tue 10 May 2022 14:19:34 AEST ]]> Multi-scale study of the hydro-mechanical behaviour of Maryland clay https://novaprd-lb.newcastle.edu.au/vital/access/ /manager/Repository/uon:31324 Tue 08 May 2018 18:05:38 AEST ]]> Deformation and fabric in compacted clay soils https://novaprd-lb.newcastle.edu.au/vital/access/ /manager/Repository/uon:33676 Tue 04 Dec 2018 16:13:50 AEDT ]]> Effect of micro silica on fiber-reinforced self-compacting composites containing ceramic waste https://novaprd-lb.newcastle.edu.au/vital/access/ /manager/Repository/uon:41185 Thu 28 Jul 2022 11:05:25 AEST ]]> Chipping of ceramic-based dental materials by micrometric particles https://novaprd-lb.newcastle.edu.au/vital/access/ /manager/Repository/uon:50534 Thu 27 Jul 2023 16:48:16 AEST ]]> Reaction kinetics in Ti3SiC2 synthesis studied by time-resolved neutron diffraction https://novaprd-lb.newcastle.edu.au/vital/access/ /manager/Repository/uon:612 Thu 25 Jul 2013 09:10:24 AEST ]]> Crystallographic preferred orientation of quartz deformed at granulite conditions: the Kalinjala Shear Zone, Port Neill, South Australia https://novaprd-lb.newcastle.edu.au/vital/access/ /manager/Repository/uon:51877 slip is characteristic for these high-temperature deformation conditions. A small asymmetry in the [c], {a} and {m} pole figures suggests a minor component of dextral shearing. The c-axis pattern is weakened where the foliation is dominated by secondary phases, such as concentrations of biotite mica. The opening angles obtained from cross-girdle c-axis patterns produce temperature estimates that are ∼100 °C lower than the peak metamorphic temperature of ∼800±50 °C, but closer to temperatures related to a component of flattening strain. These c-axis patterns are consistent with other structural characteristics and can be related to the late-stage flattening strains during the Kimban Orogeny. KEY POINTS Mylonitic orthogneisses are deformed under granulite facies conditions. Quartz fabrics were measured by bulk neutron diffraction and optical methods. Mylonite c-axis fabrics can be related to the high-temperature deformation and activation of the prism-< a > slip system. Crystal preferred orientations indicate a large component of flattening strain superimposed on the dextral shearing observed in the Kalinjala Shear Zone.]]> Thu 21 Sep 2023 10:25:16 AEST ]]> Metallurgy and Corrosion Resistance of 360 Year Old Cast Iron Pipe from Versailles Palace https://novaprd-lb.newcastle.edu.au/vital/access/ /manager/Repository/uon:48975 Thu 20 Apr 2023 12:08:53 AEST ]]> Experimental study on the hydro mechanical behaviour of compacted loess-role of soil microstructure https://novaprd-lb.newcastle.edu.au/vital/access/ /manager/Repository/uon:37754 Thu 14 Mar 2024 09:02:20 AEDT ]]> Investigation of eco-friendly fiber-reinforced geopolymer composites incorporating recycled coarse aggregates https://novaprd-lb.newcastle.edu.au/vital/access/ /manager/Repository/uon:40413 Thu 14 Jul 2022 12:08:11 AEST ]]> Durability and microstructure properties of SBR-modified concrete containing recycled asphalt pavement https://novaprd-lb.newcastle.edu.au/vital/access/ /manager/Repository/uon:44053 Thu 06 Oct 2022 15:55:08 AEDT ]]> Long-term marine immersion corrosion of welded ABS grade steels https://novaprd-lb.newcastle.edu.au/vital/access/ /manager/Repository/uon:49206 Sun 07 May 2023 09:30:32 AEST ]]> Long term localised corrosion of marine steel piling welds https://novaprd-lb.newcastle.edu.au/vital/access/ /manager/Repository/uon:13621 Sat 24 Mar 2018 10:34:53 AEDT ]]> Effect of naturally occurring salts on tensile and shear strength of sealed granular road pavements https://novaprd-lb.newcastle.edu.au/vital/access/ /manager/Repository/uon:15168 Sat 24 Mar 2018 08:22:38 AEDT ]]> Metamorphism and deformation of mafic and felsic rocks in a magma transfer zone, Stewart Island, New Zealand https://novaprd-lb.newcastle.edu.au/vital/access/ /manager/Repository/uon:18266 Sat 24 Mar 2018 08:04:23 AEDT ]]> On the mechanical properties of heat-treated expanded perlite-aluminium syntactic foam https://novaprd-lb.newcastle.edu.au/vital/access/ /manager/Repository/uon:19857 Sat 24 Mar 2018 07:57:03 AEDT ]]> Time- and density-dependent microstructure features of compacted bentonite https://novaprd-lb.newcastle.edu.au/vital/access/ /manager/Repository/uon:18804 Sat 24 Mar 2018 07:51:07 AEDT ]]> Multi-scale characterization of the retention and shrinkage behaviour of four Australian clayey soils https://novaprd-lb.newcastle.edu.au/vital/access/ /manager/Repository/uon:26294 Sat 24 Mar 2018 07:40:41 AEDT ]]> Relationship between microstructure and elemental segregation to the long-term corrosion performance of cast iron water pipes https://novaprd-lb.newcastle.edu.au/vital/access/ /manager/Repository/uon:28671 Sat 24 Mar 2018 07:37:11 AEDT ]]> Multi-scale characterization of swelling behaviour of compacted Maryland clay https://novaprd-lb.newcastle.edu.au/vital/access/ /manager/Repository/uon:26071 Sat 24 Mar 2018 07:31:30 AEDT ]]> Experimental study on effects of CO₂ concentrations on concrete carbonation and diffusion mechanisms https://novaprd-lb.newcastle.edu.au/vital/access/ /manager/Repository/uon:25538 Sat 24 Mar 2018 07:26:03 AEDT ]]> Pumice/aluminium syntactic foam https://novaprd-lb.newcastle.edu.au/vital/access/ /manager/Repository/uon:28103 Sat 24 Mar 2018 07:24:55 AEDT ]]> Changes in mineralogy, microstructure, compressive strength and intrinsic permeability of two sedimentary rocks subjected to high-temperature heating https://novaprd-lb.newcastle.edu.au/vital/access/ /manager/Repository/uon:24757 Sat 24 Mar 2018 07:14:04 AEDT ]]> Microstructural effects of environmental salinity on unbound granular road pavement material upon drying https://novaprd-lb.newcastle.edu.au/vital/access/ /manager/Repository/uon:23927 Sat 24 Mar 2018 07:10:13 AEDT ]]> Influence of pore water salinity on the compressibility of Maryland clay https://novaprd-lb.newcastle.edu.au/vital/access/ /manager/Repository/uon:44851 Mon 24 Oct 2022 11:02:59 AEDT ]]> Modeling of hydraulic fracturing in polymineralic rock with a grain-based DEM coupled with a pore network model https://novaprd-lb.newcastle.edu.au/vital/access/ /manager/Repository/uon:53272 Mon 20 Nov 2023 12:55:30 AEDT ]]> Morphological and optical properties of hierarchical tubular VOPcPhO nanoflowers https://novaprd-lb.newcastle.edu.au/vital/access/ /manager/Repository/uon:18689 Mon 20 Jul 2015 17:41:39 AEST ]]> A reduced concurrent memory access method to accelerate the computation of the lineal path function on large microstructures https://novaprd-lb.newcastle.edu.au/vital/access/ /manager/Repository/uon:55682 Mon 17 Jun 2024 10:20:10 AEST ]]> Modifications in soil fabric due to tube sampling in soft clay https://novaprd-lb.newcastle.edu.au/vital/access/ /manager/Repository/uon:33486 Mon 05 Nov 2018 13:58:42 AEDT ]]> Effect of carbon nanotubes on properties of alkali activated slag - a mechanistic study https://novaprd-lb.newcastle.edu.au/vital/access/ /manager/Repository/uon:45428 29Si NMR measurements.
