Study of the FCC+L12 two-phase region in complex concentrated alloys based on the Al–Co–Cr–Fe–Ni–Ti system

Abstract: New face-centered cubic (FCC) multicomponent alloys designed through the high-entropy (HEA) concept and strengthened with L12 ordered precipitates are promising material solutions for high temperature (HT) structural applications. However, as the design strategy is based on multi-principal elements, the research of alloy compositions exhibiting a stable and well-controlled FCC+L12 microstructure at HT is particularly challenging. Among the critical issues, those relative to the extent and the stability of the … Show more

“…Thermo-Calc now includes new databases dedicated to HEA [13]. In principle, these databases can be used for any composition and they were already proven to reproduce experimental results for various systems [10,11,44]. In TCHEA3 database, which was the most recent at the moment of the study, 8 ternary sub-systems from the Cr-Fe-Co-Ni-Mo system were assessed, compared to only 6 in TCHEA1.…”

“…They mainly consist of a γ multicomponent equiatomic FCC HEA matrix to maximize configurational entropy and utilize HEAs' unique effects, strengthened usually with γ΄ intermetallic and ideally intergranular precipitation . Al and Ti elements are usually picked as γ' stabilizers for the desirable L12 and B2 phases [48] which are suitable for high-temperature structural applications, versus their usually undesirable brittle σ, Laves or grain boundary L21 counterpart phases [49,50]. Additionally, the relatively low density of those elements is also one considerable advantage in the state-of-the-art fields like the aerospace industry.…”

“…Ph.D. Thesis 266 [294,[306][307][308][309][310]. This type of phases is extremely detrimental to the structural stability of the alloys, mainly because they deplete strengthening elements from the microstructure leading to an overall reduction in creep strength.…”
