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.
The ambitious future of India’s rail infrastructure requires prudent investments that ensure its long-term viability. This is where nickel-containing steels play a vital role.
Just as the EV revolution was gearing up to become consumer driven, there was an increase in raw material prices, semi-conductor shortages and recently a steep rise in electricity prices. At a time of energy crisis, are EVs still a game changer?
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.
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.
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.
If you’re like me and predictive text has led to some awkward if not amusing moments, you might be sceptical about Artificial Intelligence (AI). But its achievements are already overwhelming and changing, even protecting, our lives in many sectors.
Food safety starts with rigorous hygiene, and nickel-containing stainless steels are the superior, reliable standard at every link of the food chain.
Around two-thirds of today’s buildings will still be around in 2050, and by 2060, the world is projected to add 230 billion m² of buildings - an area equivalent to the entire current global building stock. What can the building and construction sector do to reduce the environmental burden of buildings?
