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.
World Food Safety Day on 7 June 2023 draws attention to food standards. Foodborne diseases affect 1 in 10 people worldwide each year, and food standards help us to ensure what we eat is safe.
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.
Major economies across the globe are setting climate neutrality targets. But proper measurement and methodologies are needed to provide transparency and common benchmarks when assessing carbon footprint. At a recent event in China, there was general consensus on the importance of adopting a harmonized approach to carbon footprint calculation and disclosure.
Even small quantities of nickel in an application can make a big difference to successful deployment.
“There’s a mental hurdle to get over of how inherently gross this could be, but we know that this water is safe, and we stand by our process.”
The many new and innovative applications of hydrogen as fuel show great promise for a greener future.
Steven Verpaele, the Nickel Institute’s Industrial Hygienist explains the different ways that the work he leads is helping to contributing to the culture of occupational safety and health that respects the right to a safe and healthy working environment at all levels.
Dr. Ilias Belharouak is the head of electrification and energy storage at the Oak Ridge National Laboratory. In this Battery Chat, he talks to Parri Adeli about the various energy storage topics his group are investigating including a new class of cathodes that they developed recently and its scale-up path.
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.
New energy legislation is set to optimize China’s energy structure and boost the use of non-fossil energy. Aligning with China’s regulatory agenda, nickel will play a vital role in tomorrow’s world powered by cleaner energy.
Ever-tightening sulphur oxide (SOx) emission regulations are increasing the use of marine scrubbers globally. Scrubbers operate in a highly corrosive environment and require the resilience of nickel-containing alloys to prevent failure.
Most nickel production is destined for stainless steel. But a significant 8% is used in the production of alloy steels which are needed to deliver specific characteristics for specialised and often critical applications.
