This paper investigates the effect of strain rate on mechanical deformation and microstructural development dual-phase AlCrFe2Ni2 high-entropy alloy during quasi-static dynamic compression processes. It is revealed that as-cast composed a mixture FCC, disordered BCC, ordered B2 crystal structure phases. The shows excellent compressive properties under deformation. yield strength exceeds 600 MPa while more than 3000 at rates 30% conditions. Under conditions, ultimate stresses are 1522 MPa,...
In this work, a series of Fe-free AlCoaCrbNic (AlCo1.31Cr0.5Ni2.4, AlCo1.71Cr0.5Ni2.0, AlCo1.8Cr0.6Ni1.8, and AlCo1.16CrNi2.0 denoted as E1, E2, E3, E4, respectively) medium-entropy alloys (MEAs) were designed though the mathematical model. Among four MEAs, E2 E3 exhibit uniform typical eutectic structural characteristics, consisting face-centered cubic (FCC) ordered body-centered (B2) phases, with FCC (L12) nanoprecipitates uniformly distributed in matrix. The E4 alloy is composed primary...
In this study, we establish a mathematical rule for accelerating the prediction of low-cost Co-free AlCraFebNic FCC/B2-structured eutectic medium entropy alloys (EMEAs). The formulas are c ≥ 1.0, 4.38a + 4.28b 3.97c ≈ 20.55, and − ˃ 1.0. With rule, successfully predict AlCr1.18FeNi2.8 AlCrFe1.46Ni2.5 verify their morphology by experiments. Both EHEAs exhibit excellent compressive mechanical properties, with yield stress higher than 500 MPa, fracture strength 2450 strain > 40%, which can...
