Heat-resisting iron-nickel base alloys in challenging new applications: oxygen permeabilities and resistance to internal oxidation. There is a pressing need to develop heat resisting alloys which can function adequately in higher operating temperatures and gas mixtures rich in carbon and hydrogen to be handled in advanced technologies for power generation. The expected outcomes of this project will provide the basis for design/selection of these more corrosion-resistant alloys.
Reducing gas and ash corrosion in advanced power generation. Advanced power generation using new coal combustion technologies increases energy efficiency and makes carbon dioxide capture possible, but increases the corrosion problems. This project aims to determine the corrosion behaviour of chromia-scale forming iron- and nickel-base alloys in the presence of deposits (coal ashes and salts) under carbon dioxide rich gas atmospheres.

This project aims to determine the corrosion behaviour of chromia-scale forming iron- and nickel-base alloys in the presence of deposits (coal ashes and salts) under carbon dioxide rich gas atmospheres. The increased understanding of alloy behaviour in hot corrosive ashes and gases, will permit more effective materials design and selection leading to more efficient and economic technologies for reliable and low cost carbon capture in energy production, waste-energy conversion and related industries.Read moreRead less
High temperature corrosion induced by multiple secondary oxidants . Heat resisting chromia-forming alloys passivate successfully in clean, dry air at temperatures up to about 950°C. However, this performance is degraded by secondary oxidants (carbon, sulphur, chlorine, water vapour), leading to corrosion failure in important industries. The project aims to investigate the effect of these secondary oxidants on corrosion behaviour of chromia-forming alloys, to identify interactions between multipl ....High temperature corrosion induced by multiple secondary oxidants . Heat resisting chromia-forming alloys passivate successfully in clean, dry air at temperatures up to about 950°C. However, this performance is degraded by secondary oxidants (carbon, sulphur, chlorine, water vapour), leading to corrosion failure in important industries. The project aims to investigate the effect of these secondary oxidants on corrosion behaviour of chromia-forming alloys, to identify interactions between multiple oxidants within the scale, to establish the mechanisms of oxide scale penetration by foreign species, and to evaluate scales on different alloy types. The results will provide a basis for improved design/selection of heat resisting chromia-forming alloys, key to power generation industries.Read moreRead less
Influence of hydrogen on metallic components for clean energy. Hydrogen (H) energy technology for a future H economy, and much of the world's current electricity generation by H-cooled turbogenerators, rely on the availability of affordable materials that are resistant to hydrogen embrittlement (HE), sudden mechanical failure owing to absorption of H atoms. This project will lead to better understanding of the HE resistance of commercial medium-strength steels for use in H pipelines and pressure ....Influence of hydrogen on metallic components for clean energy.

This project will lead to better understanding of the HE resistance of commercial medium-strength steels for use in H pipelines and pressure vessels, and of the specific steels used in turbogenerator components. More efficient, cheaper and safer clean energy will be the result.Read moreRead less

Rock bolts are the most effective means of roof support in underground mines and, as a consequence, rock bolts are widely used in the mining industry worldwide. Failure of rock bolts by SCC has significant safety and economic implications. The consequent rock falls have the potential to kill or main any person caught underneath. If a stoppage is caused of the long wall operation in a typical Australian colliery, the typical value of the lost production is of the order of a million dollars a day.Read moreRead less
