Advanced Testing and Structural Analysis for Assessment and Control of Hydrogen Damage in Structural Steels. Hydrogen offers the potential for reducing emissions in transport and energy generation industries as it is a low emission energy carrier. However, there remain questions in relation to the effects of hydrogen gas on the structural integrity of large structural steel components, such as gas distribution pipelines. The project aims to provide guidance on the safe use of hydrogen in high pr ....Advanced Testing and Structural Analysis for Assessment and Control of Hydrogen Damage in Structural Steels. Hydrogen offers the potential for reducing emissions in transport and energy generation industries as it is a low emission energy carrier. However, there remain questions in relation to the effects of hydrogen gas on the structural integrity of large structural steel components, such as gas distribution pipelines. The project aims to provide guidance on the safe use of hydrogen in high pressure vessels manufactured from low alloy ferritic steels. This project will increase confidence in relevant safety codes and standards, consequently increasing the likelihood of large scale uptake of hydrogen energy technologies. Read moreRead less
Developing a scientific relationship between non-destructive testing ("NDT"), manufacturing acceptance levels and integrity requirements for pressure equipment welds. The acceptance of pressure equipment welds involves the interplay of three engineering fields: manufacturing acceptance standards, non-destructive testing and structural integrity analysis. Historically each of these fields has been developed separately by different research groups. In recent years these developments have acceler ....Developing a scientific relationship between non-destructive testing ("NDT"), manufacturing acceptance levels and integrity requirements for pressure equipment welds. The acceptance of pressure equipment welds involves the interplay of three engineering fields: manufacturing acceptance standards, non-destructive testing and structural integrity analysis. Historically each of these fields has been developed separately by different research groups. In recent years these developments have accelerated with new demands on failure risk, a revolution in NDT techniques and advances in structural integrity analysis. As a result there are now large inconsistencies between the various requirements which lead to serious disputes in industry.
This project seeks to redefine the appropriate relationship between the fields and develop a scientific and logical pathway for standards development.Read moreRead less
Modelling and control of electromagnetically propelled arcs in joining processes. Magnetically impelled arc butt (MIAB) joining is a non-traditional manufacturing process for tubular steel components. Parameter selection and tuning have to date been experimentally determined via exhaustive trial-and-error techniques. Therefore the full capabilities of the process have not yet been realised. The project aims to model and optimise the complex process and thus facilitate the development of new a ....Modelling and control of electromagnetically propelled arcs in joining processes. Magnetically impelled arc butt (MIAB) joining is a non-traditional manufacturing process for tubular steel components. Parameter selection and tuning have to date been experimentally determined via exhaustive trial-and-error techniques. Therefore the full capabilities of the process have not yet been realised. The project aims to model and optimise the complex process and thus facilitate the development of new and effective control strategies. It is expected that novel power source designs will emerge as an outcome of the research proposed.Read moreRead less

DETERMINATION OF SUSCEPTIBILITY TO ENVIRONMENTALLY-ASSISTED CRACKING OF SMALL AND MICROSTRUCTURALLY VARIED REGIONS WHILE MAINTAINING FRACTURE MECHANICS VALIDITY. The proposed work seeks to develop an improved tool for more accurate design data and improved materials selection criteria for critical equipment and infrastructure maintenance in major Australian industries, where environmentally-assisted cracking is a serious concern (viz., marine, polymer/chemical processing, aeronautical, alumina m ....DETERMINATION OF SUSCEPTIBILITY TO ENVIRONMENTALLY-ASSISTED CRACKING OF SMALL AND MICROSTRUCTURALLY VARIED REGIONS WHILE MAINTAINING FRACTURE MECHANICS VALIDITY. The proposed work seeks to develop an improved tool for more accurate design data and improved materials selection criteria for critical equipment and infrastructure maintenance in major Australian industries, where environmentally-assisted cracking is a serious concern (viz., marine, polymer/chemical processing, aeronautical, alumina mineral processing and pulp-and-paper). A successful validation of the novel testing approach (namely, Spiral Notch Torsion Test (SNTT)) for evaluating the stress corrosion cracking (SCC) susceptibility of materials of practical interest that are difficult or impossible to adequately characterize by conventional tests, is as much a fundamental research challenge as its accomplishment will be industrially attractive.Read moreRead less

Improvement in Stress Corrosion Cracking Resistance of Stainless Steels in Environments Conducive to Localized Pitting Damage. Stress corrosion cracking (SCC) represents a serious threat to infrastructure exposed to chloride and caustic environments. The proposed project will characterize the chloride-SCC crack propagation parameters for a super duplex stainless steel, which is the material of construction for vessels for stripping vinyl chloride monomer in a PVC processing plant.

Stress corrosion cracking (SCC) represents a serious threat to infrastructure exposed to chloride and caustic environments. The proposed project will characterize the chloride-SCC crack propagation parameters for a super duplex stainless steel, which is the material of construction for vessels for stripping vinyl chloride monomer in a PVC processing plant. Alarmingly high numbers the welds (nearly 50%) in the vessel had suffered extensive pitting (which is a well-known SCC initiator) and SCC cracking. For the mitigation measures, the project will also investigate pitting and SCC susceptibility of weldments of alternative varieties of stainless steels, such as Zeron 100.Read moreRead less
