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.
Nickel-based catalysts are key to supplying energy to power our transportation of goods and people, whether by land, sea, or air.
According to the International Energy Agency, renewable fuel demand is expected to grow rapidly over the next few years. Steve Deutsch from The Catalyst Group explains the role of nickel catalysts and the potential of renewable fuels.
Electric vehicles are quickly becoming more commonplace as automakers introduce new models designed to appeal to a wider range of consumers. One thing they all have in common is a battery, most of which use nickel. Here’s the scoop on why nickel is used in EV batteries and what it’s like driving with one in an electric vehicle.
Can you mix stainless alloys in the same construction? What guidelines are there for mixing and matching alloys for success? Let’s look at a few cases.
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.
“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 use of food crops for the production of fuel is somewhat controversial. But cellulosic ethanol production facilities increase the utilization of plant waste, reduce competition for food crops and provide a substitution for fossil fuels. And nickel-containing alloys are central to this game-changing revolution.
