Title: High-entropy Al_0.3CoCrFeNi alloy fibers with high tensile strength and ductility at ambient and cryogenic temperatures

Abstract

High-entropy alloys (HEAs) are multi-component systems based on novel alloy composition designs with entropy maximization. They feature an array of unique mechanical properties when compared with traditional alloys. In this study, HEA fibers with diameters ranging from 1 to 3.15 mm in diameter, with the composition of Al_0.3CoCrFeNi (atomic percent, at.%), were successfully fabricated by hot-drawing, followed by microstructural characterization using scanning-electron microscopy (SEM) and transmission-electron microscopy (TEM). The compositional variations within and between fibers were determined using energy-dispersive X-ray spectroscopy in TEM along with atomic-probe tomography (APT). These analyses revealed a homogeneous face-centered cubic (FCC) structure in the as-cast material, while post processing (e.g., forging and wire drawing) produced nanosized B2 particles in an FCC matrix. Electron back-scatter diffraction (EBSD) was used to determine the evolution of the texture and grain boundary character after processing of the fibers. The tensile strength and plasticity of the fibers were determined at both 298 K (1207 MPa/7.8%) and 77 K (1600 MPa/17.5%). Detailed TEM analyses revealed that the improvement of mechanical properties at 77 K (i.e. increased strength and ductility) is due to a change in deformation mechanisms from the planar slip of dislocations to nano-twinning. Such properties could be beneficial formore » cryogenic applications.« less

Secondary phases in Al_xCoCrFeNi high-entropy alloys: An in-situ TEM heating study and thermodynamic appraisal

Journal Article Rao, J. C. ; Diao, H. Y. ; Ocelík, V. ; ... - Acta Materialia

Secondary phases, either introduced by alloying or heat treatment, are commonly present in most high-entropy alloys (HEAs). Understanding the formation of secondary phases at high temperatures, and their effect on mechanical properties, is a critical issue that is undertaken in the present paper, using the Al_xCoCrFeNi (x = 0.3, 0.5, and 0.7) as a model alloy. The in-situ transmission-electron-microscopy (TEM) heating observation, an atom-probe-tomography (APT) study for the reference starting materials (Al_0.3 and Al_0.5 alloys), and thermodynamic calculations for all three alloys, are performed to investigate (1) the aluminum effect on the secondary-phase fractions, (2) the annealing-twinning formation in themore »« less

Experimental and Computational Investigation of High Entropy Alloys for Elevated-Temperature Applications

Technical Report Liaw, Peter ; Zhang, Fan ; Zhang, Chuan ; ...

To create and design novel structural materials with enhanced creep-resistance, fundamental studies have been conducted on high-entropy alloys (HEAs), using (1) thermodynamic calculations, (2) mechanical tests, (3) neutron diffraction, (4) characterization techniques, and (5) crystal-plasticity finite-element modeling (CPFEM), to explore future candidates for next-generation power plants. All the constituent binary and ternary systems of the Al-Cr-Cu-Fe-Mn-Ni and Al-Co-Cr-Fe-Ni systems were thermodynamically modeled within the whole composition range. Comparisons between the calculated phase diagrams and literature data are in good agreement. Seven types of HEAs were fabricated from Al-Cr-Cu-Fe-Mn-Ni and Al-Co-Cr-Fe-Ni systems. The Al_xCrCuFeMnNi HEAs have disordered [face-centered cubic (FCC) +more »« less

Deformation mechanisms in amorphous Ni–Mo–P films coated on CoCrFeNi high-entropy alloys

Journal Article Song, X. T. ; Guo, R. P. ; Wang, Z. ; ... - Intermetallics

The Ni–Mo–P amorphous films were successfully deposited on the CoCrFeNi high-entropy alloys by electroless plating. This work will focus on reviewing and discussing the ambient-temperature mechanical properties, plastic deformation, and cracking mode of the coating-substrate system. The yielding strength (σ_y) and ultimate tensile strength (UTS) of the specimen plating for 1 h were 260 and 760 MPa, respectively, with 44.4% (σ_y) and 14.2% (UTS) improvement contrast to the uncoated HEAs (σ_y and UTS are 180 MPa and 560 MPa, respectively). It is attributed to the back stress and repulsive image stress to suppress the nucleation and mobility of dislocations. Duemore »« less

High-velocity deformation of Al_0.3CoCrFeNi high-entropy alloy: Remarkable resistance to shear failure

Journal Article Li, Z. ; Zhao, S. ; Diao, H. ; ... - Scientific Reports

Here, the mechanical behavior of a single phase (fcc) Al_0.3CoCrFeNi high-entropy alloy (HEA) was studied in the low and high strain-rate regimes. The combination of multiple strengthening mechanisms such as solid solution hardening, forest dislocation hardening, as well as mechanical twinning leads to a high work hardening rate, which is significantly larger than that for Al and is retained in the dynamic regime. The resistance to shear localization was studied by dynamically-loading hat-shaped specimens to induce forced shear localization. However, no adiabatic shear band could be observed. It is therefore proposed that the excellent strain hardening ability gives rise tomore »« less

In-situ visualization of corrosion behavior of Al CoCrFeNi high-entropy alloys during electrochemical polarization

Journal Article Shi, Yunzhu ; Mo, Jingke ; Zhang, Feng-Yuan ; ... - Journal of Alloys and Compounds

In this study, the corrosion behavior of the Al_xCoCrFeNi (x = 0.3, 0.5, 0.7) high-entropy alloys (HEAs) is investigated by an in-situ visualization system. Surface morphology changes on both micro-spatial and temporal scales are monitored in the 3.5 wt% NaCl solution during the potentiodynamic polarization. The microstructures of the Al_xCoCrFeNi HEAs are characterized by SEM, EBSD, and EDS. The results show that the microstructure evolves from singe face-centered cubic (FCC) phase to multi-phases by increasing the Al content. The in-situ observations directly reveal the different localized corrosion processes in the AlxCoCrFeNi HEAs. In the single FCC phase Al_0.3CoCrFeNi HEA, localizedmore »« less
