“…Addition of Ti to Al-Co-Cr-Cu-Fe-Ni usually leads to formation of intermetallic phases such as the Laves phase, [15,[75][76][77][78][79] σ phase, [17,75,76] Heusler phase, [17] η-Ni 3 Ti, [17,50] and R phase. [76] This is because Ti Figure 8.…”

High-entropy alloys (HEAs) are alloys with five or more principal elements. Due to the distinct design concept, these alloys often exhibit unusual properties. Thus, there has been significant interest in these materials, leading to an emerging yet exciting new field. This paper briefly reviews some critical aspects of HEAs, including core effects, phases and crystal structures, mechanical properties, high-temperature properties, structural stabilities, and corrosion behaviors. Current challenges and important future directions are also pointed out.

“…Studies regarding the magnetic properties of HEAs are mainly focused in alloys derived from Al−Co−Cr−Cu−Fe−Ni−Ti [16][17][18][19][20][21][22][23][24]. These alloys usually contain more than 50 at.% of magnetic elements (Fe, Co, and Ni).…”

“…Addition of Cu only leads to the formation of Cu-rich interdendrite phase and does not affect the CoCrFeNi FCC solid solution much. Thus, the CoCrFeNiCu alloy remains paramagnetic [16]. Addition of Al to CoCrFeNi transforms its single FCC structure to BCC+B2 phases [18,26].…”

“…Different from the traditional alloys that form complex phases, HEAs may form simple solid-solution structures like the face-centered cubic (FCC) and body-centered cubic (BCC) ones. HEAs demonstrate superior potential for engineering applications due to their high strength, hardness, wear resistance, high-temperature softening resistance and oxidation resistance [3,4].…”

A series of high entropy alloys (HEAs), Al x NbTiMoV, was produced by a vacuum arc-melting method. Their microstructures and compressive mechanical behavior at room temperature were investigated. It has been found that a single solid-solution phase with a body-centered cubic (BCC) crystal structure forms in these alloys. Among these alloys, Al 0.5 NbTiMoV reaches the highest yield strength (1,625 MPa), which should be attributed to the considerable solid-solution strengthening behavior. Furthermore, serration and crackling noises near the yielding point was observed in the NbTiMoV alloy, which represents the first such reported phenomenon at room temperature in HEAs.
