Title: High strength and high ductility in a novel Fe_40.2Ni_11.3Mn₃₀Al_7.5Cr₁₁ multiphase high entropy alloy

Abstract

In the present study, a novel Fe_40.2Ni_11.3Mn₃₀Al_7.5Cr₁₁ high entropy alloy displaying an excellent com- bination of high strength and high ductility has been developed. The b.c.c.þB2/f.c.c. dendritic- interdendritic microstructure was characterized using scanning electron microscopy, X-ray diffraction, and transmission electron microscopy, and the alloy’s mechanical properties were examined using Vickers hardness measurements and room-temperature tensile tests. The phase stability of Fe_40.2Ni_11.3Mn₃₀Al_7.5Cr₁₁ was investigated by annealing the alloy between 1173 Ke1273 K, and the presence of both Ni-rich, b.c.c. needle-shaped precipitates and Cr-rich, s phase particles was observed for the 1173 K annealed specimen. The s phase precipitates contributed to the rapid age-hardening effect in the material annealed at 1173 K. A further increase in ageing temperature to 1223 K and 1273 K led to the dissolution of the s phase and a reduction in the volume fraction of the b.c.c./B2 dendrites, which led to a consequent drop in room-temperature yield strength from the as-cast value of ~593 MPae~486 MPa and ~228 MPa for the specimens annealed at 1223 K and 1273 K, respectively. An accompanying increase in ductility was observed from ~22% for the as-cast alloy to ~27% and ~40% after annealing the material at 1223 K and 1273 K,more »« less

Post-deformation transmission electron micrographs revealed that the f.c.c interdendrites accommodated plastic strain via wavy slip and moreover, deformed before the b.c.c. dendritic regions, which were reinforced by B2 particles and acted as obstacles to moving dislocations. Finally, the discovery of a multi-phase HEA that contains 11% Cr and good mechanical properties has relevant high-temperature structural applications especially in cases that require suitable corrosion resistance.},

The effects of carbon on the phase stability and mechanical properties of heat-treated FeNiMnCrAl high entropy alloys

Journal Article Wu, Margaret ; Li, Zhiming ; Gault, Baptiste ; ... - Materials Science and Engineering. A, Structural Materials: Properties, Microstructure and Processing

This work systematically investigates the effect of carbon on the phase stability and room- temperature tensile performance of an annealed Fe_40.4Ni_11.3Mn_34.8Al_7.5Cr₆ (at%) high entropy alloy without (HEA) and with 1.1% carbon (CHEA). Four annealing conditions were investigated: 773 K for 13 d and 42 d, 973 K for 20 d, and 1073 K and 1423 K for 24 h. The resulting microstructures were analyzed using a combination of scanning electron microscopy (SEM), transmission electron microscopy (TEM), energy dispersive spectroscopy (EDS), and atom probe tomography (APT). Vickers hardness testing and room- temperature tensile testing were used to determine the mechanical propertiesmore »« less

The effect of carbon on the microstructures, mechanical properties, and deformation mechanisms of thermo-mechanically treated Fe_40.4Ni_11.3Mn_34.8Al_7.5Cr₆ high entropy alloys

Journal Article Wang, Zhangwei ; Baker, Ian ; Guo, Wei ; ... - Acta Materialia

We investigated the effects of cold rolling followed by annealing on the mechanical properties and dislocation substructure evolution of undoped and 1.1 at. % carbon-doped Fe_40.4Ni_11.3Mn_34.8Al_7.5Cr₆ high entropy alloys (HEAs). X-ray diffraction, scanning electron microscopy (SEM), transmission electron microscopy (TEM) and atom probe tomography (APT) were employed to characterize the microstructures. The as-cast HEAs were coarse-grained and single phase f.c.c., whereas the thermo-mechanical treatment caused recrystallization (to fine grain sizes) and precipitation (a B2 phase for the undoped HEA; and a B2 phase, and M₂₃C₆ and M₇C₃ carbides for the C-doped HEA). Carbon, which was found to have segregated tomore »« less

Effect of Ti content on the microstructure and mechanical behavior of (Fe₃₆Ni₁₈Mn₃₃Al₁₃)_100–xTi_x high entropy alloys

Journal Article Wang, Zhangwei ; Wu, Margaret ; Cai, Zhonghou ; ... - Intermetallics

The microstructure and mechanical properties studies of a series of two-phase f.c.c./B2 (ordered b.c.c.) lamellar-structured, high entropy alloys (HEA) Fe36Ni18Mn33Al13Tix. with x up to 6 at. % Ti have been investigated. X-ray microanalysis in a TEM showed that the Ti resided mostly in the B2 phase. The lamellar spacing decreased significantly with increasing Ti content from 1.56 mu m for the undoped alloy to 155 nm with an addition of 4 at. % Ti, leading to a sharp increase in room-temperature yield strength, sigma(y), from 270 MPa to 953 MPa, but with a concomitant decrease in ductility from 22% elongationmore »« less

The effects of annealing on the microstructure and mechanical properties of Fe₂₈Ni₁₈Mn₃₃Al₂₁

Journal Article Meng, Fanling ; Qiu, Jingwen ; Baker, Ian ; ... - Journal of Materials Science

In this paper, As-cast Fe₂₈Ni₁₈Mn₃₃Al₂₁, which consists of aligned, 50 nm, (Ni, Al)-rich B2, and (Fe, Mn)-rich f.c.c. phases, was annealed at a variety of temperatures up to 1423 K and the microstructure and mechanical properties were examined. It was shown that the as-cast microstructure arises from a eutectoid transformation at ~1300 K. Annealing at temperatures ≤1073 K produces β-Mn-structured precipitates and hardness values up to 816 HV, while annealing at temperatures >1073 K leads to dramatic coarsening of the two-phase B2/f.c.c. microstructure (up to 5.5 µm after 50 h at 1273 K), but does not lead to β-Mn precipitation.more »« less

The effect of interstitial carbon on the mechanical properties and dislocation substructure evolution in Fe_40.4Ni_11.3Mn_34.8Al_7.5Cr₆ high entropy alloys

Journal Article Wang, Zhangwei ; Baker, Ian ; Cai, Zhonghou ; ... - Acta Materialia

A systematic study of the effects of up to 1.1 at. % carbon on the mechanical properties and evolution of the dislocation substructure in a series of a high entropy alloys (HEA) based on Fe_40.4Ni_11.3Mn_34.8Al_7.5Cr₆ is presented. Transmission electron microscopy (TEM), synchrotron X-ray diffraction (XRD) and atom probe tomography (APT) were used to show that all the alloys are single-phase f.c.c. random solid solutions. The lattice constant, determined from synchrotron XRD measurements, increases linearly with increasing carbon concentration, which leads to a linear relationship between the yield strength and the carbon concentration.
