Studies on metal dusting : reaction mechanisms and their control. Gases which are supersaturated with carbon can react at high temperatures with steels and nickel-base alloys to destroy them, producing a dust of carbon plus metal and/or metal carbides. The mechanism is not properly understood, and the rate of the process impossible to predict. This program will dissect the mechanism using kinetic studies and electron microscopy of precisely located parts of the reacting system. Ways of controll ....Studies on metal dusting : reaction mechanisms and their control.

The mechanism is not properly understood, and the rate of the process impossible to predict. This program will dissect the mechanism using kinetic studies and electron microscopy of precisely located parts of the reacting system. Ways of controlling the process via alloy compositional changes will be explored.Read moreRead less
"Metal dusting" of austenitic alloys: mechanisms and interventions. "Metal dusting" is a catastrophic form of metal corrosion which we do not yet understand. It affects industries important to Australia: reforming of natural gas and (potentially) ceramic oxide fuel cells. This project aims to understand the process of austenitic alloy dusting, and thereby design materials to resist this form of attack. This will allow new natural gas processing industries in Australia to be internationally compe ...."Metal dusting" of austenitic alloys: mechanisms and interventions.

Controlling corrosion of steel by carbon dioxide-rich gases at high temperatures. A growing difficulty for Australia is the need to reduce carbon dioxide (CO2) emissions whilst maintaining the economic advantages of coal fired power stations. Technologies for capturing CO2 from these stations are being developed, but inevitably involve the need to handle hot CO2-rich gases. These are surprisingly corrosive to the materials of which power stations are constructed, in a way which is not fully unde ....Controlling corrosion of steel by carbon dioxide-rich gases at high temperatures. A growing difficulty for Australia is the need to reduce carbon dioxide (CO2) emissions whilst maintaining the economic advantages of coal fired power stations. Technologies for capturing CO2 from these stations are being developed, but inevitably involve the need to handle hot CO2-rich gases. These are surprisingly corrosive to the materials of which power stations are constructed, in a way which is not fully understood. This project aims to achieve this understanding, and to provide the basis for future alloy design.Read moreRead less

The establishment of the first Spark Plasma Sintering (SPS) facility would significantly enhance Australia's capacity in manufacturing of advanced materials, especially the more sophisticated and specialized materials, which is a National Research Priority. This facility will benefit a large number of researchers and projects in Australia's premier research organisations and will also meet the needs of organisations outside the consortium. It will allow Australian researchers to remain at the leading edge of research and enhance collaborations in advanced materials nationwide. The successful outcomes of these activities will underpin the advancement in many areas of research and technology developments in the country.Read moreRead less
Theoretical and Experimental Investigation of the Wear Behaviour of NiTi Shape Memory Alloy. Exploring high wear-resistant materials is always an active issue in tribology and material engineering in order to extend the life of the wide-ranged wearing components and devices. NiTi shape memory alloy (SMA) demonstrates a superior wear resistance to stainless steel. This project aims to theoretically and experimentally exam the wear mechanism of NiTi SMA and quantify its wear rate.

Exploring high wear-resistant materials is always an active issue in tribology and material engineering in order to extend the life of the wide-ranged wearing components and devices. NiTi shape memory alloy (SMA) demonstrates a superior wear resistance to stainless steel. This project aims to theoretically and experimentally exam the wear mechanism of NiTi SMA and quantify its wear rate. The expected outcome will discover the contributions of phase transition and plasticity on the wear property of NiTi SMA, formulate a reliable wear model and stimulate the application of NiTi in tribology and modern micro-electric-mechanical systems.Read moreRead less
