Researchers at the Masdar Institute of Science and Technology are designing a new kind of steel, known as next generation steel, to improve the fuel efficiency of cars and reduce the carbon emissions they produce.

Dr. Rashid Abu Al-Rub, Associate Professor of Mechanical Engineering at Masdar Institute, is one of nine scientists commissioned by the US Department of Energy to lead the design of the next generation of advanced high strength steel that meets the light-weight, strength, flexibility, and safety requirements of the auto industry and is equivalent in price to traditional steel.

Dr. Abu Al-Rub and his graduate student Najmul Hasan Abid have developed a computational tool that can virtually design the microstructure of steel – which is what makes steel strong and flexible. By designing and examining steel at this micro structural level, they were able to predict the overall strength and formability of the proposed steel.

"This simulation tool is a highly efficient alternative to the way high-strength steels are currently being produced and tested. The tool will make it quick, easy and affordable for car manufacturers and scientists to create and test their desired steel," Dr. Abu Al-Rub said.

Steel is the material of choice for automobiles; it is very strong as well as malleable, and its cost is relatively low compared to many other metals. But steel is heavy; over two-thirds of a car's weight comes from steel, which has a substantial impact on the car's fuel efficiency, which in turn has a big impact on the amount of carbon emissions released into the atmosphere. In the US alone, about 1.7 billion tons of greenhouse gases are released into the atmosphere each year from highway vehicles, accounting for nearly 32per cent of annual carbon dioxide emissions. Here in the UAE, carbon emissions are considered a challenge to the country's air quality and overall sustainability, and the government has targeted their reduction in the Abu Dhabi Environment Policy Agenda.

Reducing a car's weight by 10 per cent can improve fuel efficiency by 6 per cent to 8 per cent, and since steel is the heaviest part of the car, it has a big role to play in making the car lighter.

After designing the microstructure of the steel, Dr. Abu Al-Rub and Abid ran several "what-if" scenarios to assess the steel's flexibility and durability in different situations and environments. After many design trials, they found that adding nanoparticles significantly enhances the steel's flexibility without compromising the strength. By adding a small fraction of nanoparticles, the steel's flexibility increased 40-50per cent.

"Rather than repeatedly building and testing the steel in a lab until coming up with the best steel – a process that takes many trial and errors, high manufacturing costs, and several months to complete – our design tool will allow users to tweak the steel's microstructure and combine various amounts of nanoparticles and other phases in order to achieve specific levels of strength and flexibility before manufacturing the steel. Once the design and combinations are finalised, then the manufacturing of the steel can commence," Dr. Abu Al-Rub added.

The novel steel has many other potential applications outside of the auto industry; the aerospace and construction industries as well as the oil and gas industry could greatly benefit from such a flexible and, light-weight metal.

"Our next step is to engage the UAE's steel industry and share with them the type of steels we have discovered. We hope that the innovative, high-grade and light-weight steel we are now validating will serve to advance and further diversify the UAE's economy and contribute to the transport sector, which is one of the seven sectors targeted in the new UAE Innovation Strategy," Dr. Abu Al-Rab added.
