The materials fabricated by mechanical alloying (MA) make a significant contribution to industrial applications. They represent a highly diverse and strongly multidisciplinary area, with links to numerous industrial sectors such as aerospace, energy, construction, automotive, transport, packaging, security and defense.
Mechanical alloying was selected as the most appropriate processing method to produce oxide dispersion strengthened (ODS) alloys that can be used at high temperature and radiation resistance applications. This special issue will include all aspects of theory, methods, materials and applications of mechanical alloying. Contributions in the following topics are encouraged.
- Synthesis and processing in solid-state science and technology: high-energy milling, severe plastic deformation of materials (SPD), reaction milling.
- New materials/processes: oxide dispersion strengthened (ODS) alloys, nanomaterial, nano-composites, and quasi-crystalline phases/materials.
- Structural characterization: mechanically induced structural changes in materials (point defects, dislocations, clusters, precipitates, grain boundaries), surfaces and interfaces in activated solids.
- New equipment and procedures: milling equipment based on improved milling dynamics, processing optimization and milling contamination.

Abstract: Severe plastic deformation of binary immiscible alloys can result in either nanostructured composites or supersaturated solutions depending on the chemical composition of the material and the amount of strain. During deformation, refinement of the microstructure takes place until a state of saturation is obtained. The kinetics of the refinement process can be adjusted by various parameters. One of these is the initial structure of the material. In this study, iron powder was coated with copper via immersion deposition. Subsequently, the coated powder was deformed using high pressure torsion. The coating of the powder does not allow any agglomeration of one element over larger regions, as it might occur in powder mixtures. Therefore, an acceleration of the structural refinement process was expected as compared to the deformation of powder mixtures. X-ray diffraction as well as scanning electron microscopy including electron backscatter diffraction was used to analyze the structure after different amounts of deformation, which was then related to the microhardness of the material. Equivalent experiments using mixtures of iron and copper powders were performed to compare the results and discuss both the avoidance of agglomeration and the enhanced presence of impurities in the coated powder.
