Bragg edge tomography of AHS-steel

With the increased demand for improving fuel economy and to lower emissions in automotive applications, the introduction of 3rd Generation AHSS (advanced high strength steels) in structural components is a possible route for the reduction of vehicle weight. 3rd generation AHSS should be hard so that less material can be used but still retaining crash safety, but also ductile for the ease of production purposes. Several of AHSS grades are mixtures of different steel components, one hard and one ductile in order to meet this properties. In industry processes which involves deformation transformation of the ductile component to the hard will occur. This beam-time application involves Bragg edge tomography. With this it is possible to see the two steel components and how they interplay in a simulated industry process when the material is deformed.
