“…8(b) gives the grain size distribution of the largely equiaxed grains, which varied in the range from 10 to 80 nm, with an average grain size of 37 nm (>200 measured grains). The grain size of the sintered sample was bigger than the corresponding cryomilled powder (26.2±7.9 nm [30]) due to grain growth during the SPS process. Coarse grains were also observed among the NC grains.…”

“…A sample designated as CM6h was cryomilled for 6h and consolidated by SPS. The sample preparation procedure can be found in our previous study [30]. A mixture of 80 wt.% cryomilled powder and 20 wt.% Mg-Zn eutectic alloy (EA) powder was fully mixed by cryomilling without grinding balls and consolidated into bulk samples under the same conditions (designated as CM6h+EA sample).…”

As of today, metals and alloys are widely utilized as structural, mechanical, electrical, and magnetic materials in every aspect of technology and industry. The complexity and diversity of metals applications emphasize the need for a new production method to quickly and easily manufacture metallic components. Spark plasma sintering as a new solidstate sintering method has been recently developed to respond to these needs. Up to now, numerous papers and researches have been published in the field of spark plasma sintering and its ability to manufacture metallic samples. Density is a significant property that has a great influence on the physical, mechanical, and functional properties of metallic parts. To the best of our knowledge, there is no concrete paper that reviews the densification behavior of metals and alloys during spark plasma sintering and the effect of its parameters on the density of metallic samples. As a result, this article dedicated to addressing this need. In this mini-review, after a short description of spark plasma sintering method, the effects of each sintering parameters on densification behavior of metals and alloys are studied, and possible physical and microstructural factors which have the effect of densification behavior of metallic samples at various sintering conditions are reviewed. Finally, the recent advances in finite element modeling, which study the temperature and stress inhomogeneity in the SPS process, have been reviewed in this paper.

Cryomilling (CM) is a vital top‐down process used for creating nanomaterials, offering advantages over traditional mechanical alloying by operating in cryogenic environments. The process minimizes cold welding, enhances particle fracture, and reduces oxidation, leading to ultrafine grains in metallic, alloys, and composite powders. CM is applicable across diverse material systems, including face‐centered cubic, body‐centered cubic, hexagonal close‐packed, and high‐entropy alloys. By examining the effects of CM on various materials with different crystal structures, this review highlights the critical role of processing parameters such as ball‐to‐powder ratio, milling speed, and the use of process control agents. The study further explores how CM enhances mechanical properties like strength and hardness, providing pathways for future research aimed at optimizing efficiency, scalability, and reducing contamination during the milling process.
