Mechanical alloying is widely recognized as a powder processing technique leading to the formation of many non-equilibrium and equilibrium structures, like extended solid solutions, amorphous alloys, nanocrystalline (nanostructured) alloys, intermetallic compounds, or in situ composites. There are many modifications to the process, depending on the nature of the transformation (alloying, milling, mechanochemical reaction). However, the final phase composition and structure always depend on thermodynamic (e.g., mutual solubility of the elements, enthalpy of mixing, differences in atomic radii) and processing (e.g., type of mill, energy of milling, ball-to-powder weight ratio, process control agent) parameters.
The next step following the mechanical alloying process is usually powder compaction, preserving their non-equilibrium structure. Various techniques are employed for powder consolidation, like cold pressing followed by sintering, hot pressing, hot isostatic pressing, explosive compaction, and spark plasma sintering. In many cases, amorphous powder compaction is an alternative to the rapid quenching (casting) technique, which can obtain bulk amorphous alloys and their composites. Compaction of mechanically alloyed powders/composites can also help to overcome many problems related to the traditional manufacturing of metal matrix composites, like particle agglomeration, low wettability, or interfacial reactions.
This Special Issue of Materials will be a detailed overview of recent research and development in the field of mechanical alloying/milling of metallic/ceramic powders followed by their compaction to get bulk amorphous/nanocrystalline materials and composites.
It is my pleasure to invite you to submit a manuscript for this Special Issue. Full papers, communications, and reviews related to mechanical alloying and powder compaction are all welcome.
