Why did it fail? When did it happen? Who is responsible? — Commonly asked questions in the field of materials failure investigations.
Materials will degrade from the moment they are put into service, for example through wear of moving components, corrosion in a harsh environment, or fatigue cracking through repeated motions. Recognising this, materials intended for critical applications are carefully selected to withstand their particular service environment. However, sometimes their expected lifetime can be cut short by an unexpected and catastrophic failure, often with a large price tag for damages and litigation.
Once the dust settles following such an incident, it becomes necessary to answer the above questions. Through forensic study of failed materials, an investigator must piece together the evidence to find the nature of the failure. This presentation outlines the process of materials failure investigation with recent case studies on corrosion, fatigue and overload.
Ammonia is a renewable fuel and an enabler for the decarbonisation of the energy sector. Since NASA’s X-15 ammonia rocket engine powered aircraft, a number of devices have been successfully powered with ammonia-based fuel blends. However, research into suitable materials that can withstand such corrosive, high temperature combustion environments is limited, and a specialist material for combustors powered by ammonia-hydrogen fuel blends does not currently exist.
This study begins by characterising the combustion environment for testing of existing alloys, including a range of high nickel and chromium superalloys. Information relating to product gases, temperatures, radicals and hydrodynamics in the combustion zone was collected, with the goal of identifying the most suitable materials that can be used as a starting point for the development of a new material for this novel application.
As the way we perceive systems of energy is changing, through the adaptation to global warming and increasing resource scarcity, we must rethink the relationship between different forms of energy and what we are headed towards as a society. In this talk, I'll outline energy storage itself as well as how different types compare and contrast with one another in nature and in science. Specifically, I'll pick apart fusion energy and how it is released and stored in a variety of forms.
Diamond is relatively new player in the field of energy storage and harvesting materials, but has huge potential for certain applications. For fusion energy in particular, diamond presents a nexus of properties which make it an ideal candidate for a brand-new type of energy ecosystem. One which will hopefully broaden your view of what is possible in the endeavour to make our societies more sustainable.
