Heather Allain, Executive Director, Materials Technology Institute (MTI), tells us about her passion for materials and the importance of MTI’s work to provide awareness of safe, reliable and sustainable materials use.
Solar farms are blooming in fields across the globe and producing a new crop: solar energy. Photovoltaic (PV) systems made up of solar panels, are fast becoming the most recognisable of renewable energy technologies.
Materials selection for any piece of equipment or a process system is rarely a simple task, unless you are exactly replicating something successful. Often engineers will have a checklist to help them narrow down the choices, eliminating groups of materials that are not suitable for various reasons. Austenitic 300 series stainless steels containing 7-35% nickel will have most if not all of the boxes checked for being suitable where a stainless steel is desired.
Each family of stainless steels has its strengths and weaknesses. Ferritic stainless steels have useful properties – a lower rate of thermal expansion, higher thermal conductivity, strong ferromagnetism and very high resistance to chloride stress corrosion cracking (SCC). When looking at selecting any alloys, it is important to consider all the factors for successful usage.
The duplex alloys are “problem-solving alloys” for good reason, they have been successfully used in many places where carbon steels and standard austenitic alloys have failed. Just like with the austenitic family, there are many different duplex alloys to choose from, with corrosion resistance varying from moderate with the lean duplex alloys to very high with the superduplex alloys.
The selection of an alloy should be guided by careful examination of the needs of the application. Before making a switch, it’s important to fully investigate an alloy’s strengths, weaknesses and applicability to your structure.
Think of the largest cruise ship. Then imagine how much it weighs – just over 100,000 tonnes, in fact. Now think about 500 of those ships, and what they weigh. That is the staggering amount of new electronic waste that we generate every year.
As delegates to the UN COP26 Climate Change conference in Glasgow grapple with the climate crisis, clean energy solutions will be in focus. Although clean energy technologies rely on metals and minerals that are unavoidably energy intensive to produce, the IEA says that the climate advantages of these technologies remain clear.
Even small quantities of nickel in an application can make a big difference to successful deployment.
The many new and innovative applications of hydrogen as fuel show great promise for a greener future.
A new generation of designers, materials specifiers, architects and engineers is being introduced to the wealth of technical information curated by the Nickel Institute. An archive of technical guides and know-how for working with nickel-containing materials, including stainless steel, that has been built over thirty years is now being updated and made freely available.
The present-day principal driver in the Li-ion industry is the large batteries required for electric vehicles. Due to the size of these batteries and the relative growth of electric vehicles it is predicted that the total Li-ion energy capacity will exceed one tera watt-hour by 2030. This anticipation for a dramatically rapidly expanding industry has stakeholders all along the value chain very motivated to be ready.
The last three months have been unprecedented. But amidst the chaos and despite the drop in global GDP, there has still been a considerable amount of activity in the electric vehicle (EV) and battery world.
