| Abstract Scope |
Synchrotron high-energy X-ray and neutron diffraction offer distinct advantages, providing complementary high resolution and bulk penetration capabilities for studying heterogeneous and anisotropic materials, including those produced through high-pressure torsion and other extreme environments. These investigations unveil comprehensive information about crystallographic properties at both integrated and local levels, such as stress, texture, disorder, and phase composition. The detailed knowledge of structural and crystallographic evolution of the far out-of-equilibrium matter allows to design unique materials with enhanced properties and microstructures.
In this study, we focus on the phase and microstructural evolution of various metals when subjected to heating. Notably, advanced synchrotron high-energy X-ray experiments employing a 3˟6 µm2 beam spot size allow us to observe microstructural changes, including recovery, recrystallization, and grain growth. We provide an overview of the methods employed and present selected examples using a range of representative metals and alloys. |
