“…Novel materials have also been synthesized by MA of blended elemental powders. One of the interesting examples in this category is the synthesis of plain carbon steels and stainless steels [55, 56]. Two main advantages of this synthesis route are that the steels can be manufactured at room temperature and that the steels will be nanostructured, thus conferring improved properties.…”

Mechanical alloying is a solid-state powder processing technique that involves repeated cold welding, fracturing, and rewelding of powder particles in a high-energy ball mill. Originally developed about 50 years ago to produce oxide-dispersion-strengthened Ni- and Fe-based superalloys for aerospace and high temperature applications, it is now recognized as an important technique to synthesize metastable and advanced materials with a high potential for widespread applications. The metastable materials produced include supersaturated solid solutions, intermediate phases, quasicrystalline phases, amorphous alloys, and high-entropy alloys. Additionally, nanocrystalline phases have been produced in virtually every alloy system. Because of the fineness of the powders, their consolidation to full density without any porosity being present is a challenging problem. Several novel methods have been developed to overcome this issue. Powder contamination during milling and subsequent consolidation constitutes another issue; this can be resolved, though expensive. A number of applications have been developed for these novel materials. This review article presents an overview of the process of mechanical alloying, mechanism of grain refinement to nanometer levels, and preparation of materials such as nanocomposites and metallic glasses. The application of mechanical alloying to synthesize some advanced materials such as pure metals and alloys, hydrogen storage materials, and energy materials is described. The article concludes with an outlook on future prospects of this technique.

“…A number of researches have come up that the milling parameters have great influences on the formation of crystals. [45] The transition of crystalline, quasi-crystalline, and amorphous states can be realized by varying the parameters, such as the weight and size of milling medium, rotation speed, and filling extents. For example, Ghobrial et al [46] synthesized a series of amorphous alloys in a Ni-Nb-Y immiscible system by mechanical alloying process.…”

Immiscible metallic systems provide new opportunities for tailoring material properties due to their unique microstructure. However, they are immiscible in the liquid state, or separate into incompatible liquid phase during the cooling process, making it difficult to obtain their alloys or phases. Mechanical alloying is a solidstate processing route, whose basic principle is to utilize mechanical impact to make materials suffer cyclic deforming, fracturing, and welding. It reduces the energy barrier and provides pathways of atom diffusion, achieving atomic-level alloying in solid-state. Notably, mechanical alloying does not undergo the cooling process from liquid to solid phase, which can avoid the solute separation. This article discusses the mechanical alloying process, microstructure, and mechanism of immiscible metallic systems. It focuses on the alloying principles, including solid solutions, intermetallic compounds, nanocrystalline or amorphous alloys. In addition, the effects of process parameters, including rotation speed, milling time, and ball-to-powder weight ratio, on microstructure and phase constitution are comprehensively reviewed. Some useful suggestions regarding the preparation of immiscible metallic systems are also put forward for future works.
