About this Research Topic
Recrystallization, grain growth and related texture evolution all play significant roles in determining the properties of metallic materials. The optimization of mechanical, electrical and chemical properties (strength, durability, formability, machinability, conductivity, electrical resistivity, corrosion resistance etc.) allow such materials to have a vast range of applications in manufacturing and technology.
In recent decades, several recrystallisation mechanisms and grain growth behaviours have been proposed by experiments and simulations in different metallic alloy systems to illustrate grain and texture evolution during processing. An example of this, is the recrystallized grain nucleation which has been reported to be particle stimulated, shear band induced and deformation twin induced nucleation. When made in the same alloy system, these results highlight the highly disputed nature of this research. Thus, establishing widely-recognised and less-disputed recrystallisation mechanisms suitable for most metallic materials through systematic research is the ever-present goal.
Recrystallization processes and related texture evolutions generally involve complex behaviours such as dislocation movements, second phase particles, grain boundary movement behaviour and phase boundary migrating competition to name a few. These all require detailed research in order to be applied to a wide range of metallic materials. Designing novel experiments to track entire recrystallization processes is key to be able to elaborate on these complex behaviours, however, this can be quite challenging to accurately monitor as some microstructures are in the nanometre scale.
The aim of this Research Topic is to focus on new innovations in the field of metallic material recrystallization, including new insights into FCC, BCC and HCP crystal structure alloy systems (e.g. Al, Fe, Ti, Mg). Properties and grain growth behaviours, as well as texture evolutions, will be correlated to optimize the microstructures for structural applications in industry. In addition to focusing on the microstructural properties through novel experiments, this Research Topic also welcomes modelling and simulation approaches to uncover new perspectives of recrystallization and metallic microstructure behaviours and properties.
Areas of interest could include, but are not limited to:
• Novel recrystallization of metallic materials
• Grain growth in metallic materials
• Complex microstructure behaviours e.g. grain boundary movement and phase transformations
• Texture evolution and property optimization of metallic materials
• Texture control for producing durable, high-performance metallic materials
• Modelling and simulation investigations into microstructure behaviours and properties
• Techniques for characterizing metallic materials
