Meeting 2022 TMS Annual Meeting & Exhibition
Symposium Ultrafine-grained and Heterostructured Materials (UFGH XII)
Presentation Title Structural Characterization and Thermal Evolution of Severe Plastic Deformation Processed Materials, by Advanced Synchrotron and Neutron Methods

On-Site Speaker (Planned) Klaus-Dieter Liss
Abstract Scope Synchrotron and neutron diffraction bear the advantage of complementary high resolution and bulk penetration to study heterogeneous and anisotropic materials as produced by high-pressure torsion and subjecting to other extreme environments. The investigations reveal integrated and local crystallographic properties, as stress, texture, disorder and phase composition. We present the phase and microstructural evolution of various metals upon heating. In particular, advanced synchrotron high-energy X-ray experiments using a 3˟6 µm2 beam spot size reveal microstructural changes, such as recovery, recrystallization and grain growth. An overview of the methods and selected examples are given on a variety of representative metals and alloys.
