Description
The thermal evolution in metals plays an utmost important role in thermo-mechanical processing. Lattice expansion not only reveals conventional thermal expansion but moreover gives insight to order parameters, change of chemical composition and pressure. Peak widths reveal microstructural changes, as well as texture evolution, while primary extinction can be used to study defect mechanisms. Quantifying anisotropic and phase related expansion mismatch allows to design alloys with better mechanical properties. Here I give an overview with selected examples on bulk zirconium alloys, aluminium alloys. Focus will be given on materials after severe plastic deformation, in which different states of thermal stress relaxation, microstructural recovery and recrystallization can be distinguished.
