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 Ám2 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.
