Design, modelling and development of new alloys

Our work focuses on developing new principles in physical metallurgy and microstructural modelling to conceive novel technologies, which will hopefully lead to a better quality of life from the point of view of engineering design and the environment.

Development of high performance steels

Combining strength, formability, corrosion and fatigue resistance along with stability at high temperatures is a major challenge in the search for new concepts in the energy and transportation industries. Such a combination of properties can in principle be attained at a low cost by steels. However, this requires the control of their properties and structure over scales ranging from atomic to engineering dimensions. Understanding and manipulating the physical and chemical properties across scales, while developing new steel grades is a major aim of our research.

Modelling and design of engineering alloys

Creating new alloys which display exceptional performance is a task achieved through the development of scientific methods which deal with complexity. The most economical way forward is with the aid of physical and computer modelling. The development of microstructures is governed by rules amenable to mathematical expression. Our models combine thermodynamic, kinetic and atomistic approaches to design new alloys.
