Recrystallization and grain growth take place during the thermal treatment of materials and as part of geological activity deep in the earthТs crust. The main objective of the Rex&GG Conference series is to provide a forum for the exchange of ideas, knowledge and information on the state-of-the art in the field. Rex&GG V will include oral and poster presentations, as well as exhibition. Topics will include, but are not limited to, recrystallization and grain growth in metals, ceramics, thin films, geological materials and nanostructured materials. Sessions will also cover the following: deformation structures; grain boundary/interface structures; static recovery and recrystallization; dynamic recovery, recrystallization and high temperature deformation; grain growth and related properties; textures; industrial control of recrystallisation and grain growth; computer simulations and modelling and advanced characterisation techniques, including 3D and in-situ methods.
