Summary
Mobile high power diode laser for thermal processing applications. This proposal seeks to establish a mobile, high-power diode laser facility for thermal processing of in-situ components in the power generation, defence, shipbuilding and mining industries. Diode lasers offer significant advantages for laser thermal processing over conventional CO2 and Nd:YAG lasers in terms of their output wavelength, size and efficiency. The mobile high power diode laser facility will help build a strong infr ....Mobile high power diode laser for thermal processing applications. This proposal seeks to establish a mobile, high-power diode laser facility for thermal processing of in-situ components in the power generation, defence, shipbuilding and mining industries. Diode lasers offer significant advantages for laser thermal processing over conventional CO2 and Nd:YAG lasers in terms of their output wavelength, size and efficiency. The mobile high power diode laser facility will help build a strong infrastructure for in-situ repair of worn components and is expected to reduce overall component repair costs and time.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
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. Alarmingly hig ....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. 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
