“…Thus, the Hall-Petch hardening contribution becomes much more important than the substructure hardening in samples rotated for angles larger than 180 • . This result is in good agreement with data reported earlier for the nanocrystalline HEA [37].…”

“…After the rotation for 180 • at cryogenic temperature, the contribution of the substructure hardening is comparable to that of the Hall-Petch hardening (Figure 7). agreement with data reported earlier for the nanocrystalline HEA [37], It is worth noting that, according to the calculations, the effective grain size in the CoCrFeNiMn alloy after HPT at 293 and 77 K is approximately equal ( Table 2). Higher strength of the sample deformed in cryogenic condition can be ascribed to the contribution of substructure (dislocation) hardening.…”

“…However, long time mechanical alloying process (usually more than 60 h) is necessary to achieve the HEAs powder [5,6]. Furthermore, the powder is often contaminated by the milling media and the environment during mechanical alloying [4][5][6]. Therefore, it is a challenge to find a method that is convenient, high-efficient and low-cost to prepare HEAs.…”

“…Using spark plasma sintering (SPS) to consolidate mechanically alloyed HEAs powder is a promising method to obtain high-performance bulk HEAs [5,6]. However, long time mechanical alloying process (usually more than 60 h) is necessary to achieve the HEAs powder [5,6]. Furthermore, the powder is often contaminated by the milling media and the environment during mechanical alloying [4][5][6].…”
