Fast in-situ X-ray micro tomography characterisation of microstructural evolution and strain-induced damage in alloys at various temperatures

Fast in-situ X-ray tomography has been used at ESRF Grenoble to characterise the microstructural evolution and the formation of strain-induced damage in various materials during different thermomechanical treatments. Materials are both light alloys (Al and Mg based alloys) and steels. The thermomechanical treatments include tensile deformation both in the solid state at room and high temperatures and in the semi-solid state together with thermal treatments above the solidus temperature. Melting and solidification of Al-alloys are also considered in this paper.
