“…This change in the deformation mechanism provides superior mechanical properties to NC materials [19]. Due to these nano-scale features, the NC materials have enhanced strength [20][21][22], improved fatigue life [23][24][25], superior wear resistance [26,27], improved hardness [20,28,29], higher specific heat [30,31], and improved coefficient of thermal expansion [32][33][34]. However, researchers also revealed that NC materials have lower ductility [35].…”

Nanostructuring is a commonly employed method of obtaining superior mechanical properties in metals and alloys. Compared to conventional polycrystalline counterparts, nanostructuring can provide remarkable improvements in yield strength, toughness, fatigue life, corrosion resistance, and hardness, which is attributed to the nano grain size. In this review paper, the current state-of-the-art of synthesis methods of nanocrystalline (NC) materials such as rapid solidification, chemical precipitation, chemical vapor deposition, and mechanical alloying, including high-energy ball milling (HEBM) and cryomilling was elucidated. More specifically, the effect of various process parameters on mechanical properties and microstructural features were explained for a broad range of engineering materials. This study also explains the mechanism of grain strengthening using the Hall-Petch relation and illustrates the effects of post-processing on the grain size and subsequently their properties. This review also reports the applications, challenges, and future scope for the NC materials.

“…However, because of its relative low wear resistance and hardness, there is a great demand for improvement in the mechanical properties and lifetime of Ti and its alloys to make them more suitable for the above-mentioned applications. For example, Ti 6 Al 4 V, which is one of the best biocompatible Ti alloys for fabrication of medical implants [ 18 ], suffers from poor tribological performance leading to the formation of fine wear debris when subjected to continuous movement from the surrounding bones [ 19 ]. These fine debris containing Al and V can be toxic to the biological system surrounding the implant, further causing its premature loosening [ 20 , 21 ].…”

“…As a result of this, NC materials offer superior mechanical properties and are considered as a potential candidate for applications that demand improved properties compared to polycrystalline materials with coarser grain structures [ 10 ]. Scholars have reported high hardness [ 11 , 12 ], enhancement in strength [ 13 , 14 ], superior wear resistance [ 15 , 16 ], improved fatigue life [ 17 , 18 ], high thermal expansion coefficient [ 19 , 20 ], and high corrosion resistance [ 21 , 22 ] for NC materials. NC materials are also reported to have seven times higher hardness and ten times higher yield strength as compared to their polycrystalline coarse grain counterparts [ 23 , 24 ].…”

The present investigation aims to develop nanocrystalline (NC) pure aluminum powders using cryomilling technique and manufacture bulk components using spark plasma sintering (SPS). The cryomilling was performed on pure Al powders for 2, 6, and 8 h. The cryomilled powders were then consolidated using SPS to produce bulk components. The particle morphology and crystallite size of the powders and the bulk SPS components were analyzed using scanning electron microscopy (SEM), X-ray diffraction (XRD), and transmission electron microscopy (TEM). The results showed that the crystallite size of pure Al powders decreases with increased cryomilling time. The results also showed that the SPS at elevated temperatures resulted in a slight increase in crystallite size, however, the changes were insignificant. The mechanical properties of the bulk components were determined using a Vickers microhardness tester. The hardness of the cryomilled SPS component was determined to be three times higher than that of the unmilled SPS component. The mechanism for the reduction in crystallite size with increasing cryomilling time is discussed. This fundamental study provides an insight into the development of bulk nanomaterials with superior mechanical properties for automotive, aerospace, marine, and nuclear applications.
