Metallic materials

Our ability to develop new or improved materials and processes depends largely on the availability of good experimental and numerical infrastructure. Modern laboratories and numerical models are necessary to describe and understand the relationship between composition and structure of materials and material properties and how this relationship is affected by processing parameters.
