Comparative irradiation response of an austenitic stainless steel with its high-entropy alloy counterpart

Irradiation Resistance of CoCrCuFeNi High Entropy Alloy under Successive Bombardment

“…The results showed that fewer or no vacancy clusters could be observed in HEA than in Fe-Cr-Ni alloys under 3 or 5.8 MeV Ni ions irradiation from room temperature to 700 °C. Tunes et al [19] also indicated that FeCrMnNi HEA was more stable to irradiation than austenitic steel in terms of the stability of the matrix phase within the wide range of irradiation configurations. Yang et al [20] pointed out that Al 0.1 CoCrFeNi HEA showed excellent phase stability under irradiation.…”

Irradiation stability and induced ferromagnetism in a nanocrystalline CoCrCuFeNi highly-concentrated alloy

“…HCAs may represent an ongoing revolution within metallurgy as they have often been reported to have superior mechanical and corrosion resistances [4][5][6] than diluted alloys, although the underlying physical mechanisms and the intrinsic alloy core-effects behind these extraordinary properties are not yet well understood. [7][8][9][10][11][12][13] A major goal in metallurgy is the design of new metallic alloys that combine superior strength and ductility with enhanced physico-chemical properties. After synthesis and specific processing, polycrystalline metallic alloys have grain sizes within the microscale which will then define the set of macroscopic properties associated with their final application.…”

Temperature effect on radiation‐induced dislocation loops in a FCC high purity CrFeMnNi multi‐principal element alloy

“…However, the presence of Co leads to a high level production of the 60 Co radioisotope under neutron irradiation, which makes it inappropriate for a use in nuclear reactors. Therefore, some CrFeMnNi multi-principal element alloys (MPEAs) were designed, fabricated and characterized, such as 18Cr-27Fe-27Mn-28Ni, 15Cr-35Fe-15Mn-35Ni, 20Cr-40Fe-20Mn-20Ni, 18Cr-29Fe-23Mn-30Ni (all the compositions in this study are given in at.%) [8][9][10][11][12][13][14].…”
