A long-term collaboration between the University and industry has resulted in a super-strong form of steel, which is now being manufactured in the UK for use as stronger and cheaper armour for front-line military vehicles. By introducing perforations into the steel, we create a large number of edges, which interrupt the path of incoming projectiles Peter Brown, MoD For thousands of years, steel has been used to make or do just about whatever we ask of it, from ancient suits of armour to modern skyscrapers. It has been mass produced since the mid-19th century, and global production of this most ubiquitous of materials currently stands at more than 1.4 billion metric tonnes per year. Although all steel consists primarily of iron and carbon, it has an almost infinite variety of properties, depending on the type or amount of other elements added to the mix, or the temperature at which the steel is produced. This complexity makes steel extremely versatile, but also very difficult to understand and to design from the atomic level. Professor Harry Bhadeshia of the Department of Materials Science and Metallurgy has spent the past three decades researching the nature of steel to develop new alloys for
