The evolution of the deformation substructure in a Ni-Co-Cr equiatomic solid solution alloy

Journal Article Miao, Jiashi ; Slone, C. E. ; Smith, T. M. ; ... - Acta Materialia

The equiatomic NiCoCr alloy exhibits an excellent combination of strength and ductility, even greater than the FeNiCrCoMn high entropy alloy, and also displays a simultaneous increase in strength and ductility with decreasing the testing temperature. To systemically investigate the origin of the exceptional properties of NiCoCr alloy, which are related to the evolution of the deformation substructure with strain, interrupted tensile testing was conducted on the equiatomic NiCoCr single-phase solid solution alloy at both cryogenic and room temperatures at five different plastic strain levels of 1.5%, 6.5%, 29%, 50% and 70%. The evolution of deformation substructure was examined using electronmore »« less

Plastic deformation of single crystals of the equiatomic Cr-Mn-Fe-Co-Ni high-entropy alloy in tension and compression from 10 K to 1273 K

Journal Article Kawamura, Marino ; Asakura, Makoto ; Okamoto, Norihiko L. ; ... - Acta Materialia

In this report the plastic deformation behavior of single crystals of the quinary, equiatomic Cr-Mn-Fe-Co-Ni high-entropy alloy (HEA) with the face-centered cubic structure has been investigated in tension and compression as a function of crystal orientation and temperature from 10 K to 1373 K. The critical resolved shear stress (CRSS) for {111}<110> slip at room temperature is 42-45 MPa. It does not depend much on crystal orientation (i.e., the Schmid law holds true) and the sense (tension vs. compression) of the applied load. The CRSS for {111}<110> slip increases with the decrease in temperature, without showing any significant inertia effects at cryogenic temperatures below 77 K. Extrapolation from the measured yield stresses down to 10 K yields a CRSS value at 0 K of 168 MPa. At cryogenic temperatures, the measured strain-rate sensitivity of flow stress is consistent with a very small activation volume. The concept of stress equivalence holds true both for the temperature dependence of CRSS and the stress dependence of activation volume, indicating that solid-solution hardening is the major strengthening mechanism. Deformation twinning occurs at 77 K but not at room temperature, resulting in higher tensile elongation to failure at 77 K than at room temperature. Deformation twinning at 77 K occurs at a shear stress of 378 MPa on conjugate (more »« less

Defect energetics of concentrated solid-solution alloys from ab initio calculations: Ni _0.5 Co _0.5 , Ni _0.5 Fe _0.5 , Ni _0.8 Fe _0.2 and Ni _0.8 Cr _0.2

Journal Article Zhao, Shijun ; Stocks, G. Malcolm ; Zhang, Yanwen - Physical Chemistry Chemical Physics. PCCP

The distribution of migration energies of vacancies and interstitials in Ni_0.5Fe_0.5has a region of overlap, an indication of their comparable mobility compared to pure Ni (indicated by dotted line), which will greatly facilitate the recombination of Frenkel pairs.

Defect energetics of concentrated solid-solution alloys from ab initio calculations: Ni_0.5Co_0.5, Ni_0.5Fe_0.5, Ni_0.8Fe_0.2 and Ni_0.8Cr_0.2

Journal Article Zhao, Shijun ; Stocks, George Malcolm ; Zhang, Yanwen - Physical Chemistry Chemical Physics. PCCP

It has been shown that concentrated solid solution alloys possess unusual electronic, magnetic, transport, mechanical and radiation-resistant properties that are directly related to underlying chemical complexity. Because every atom experiences a different local atomic environment, the formation and migration energies of vacancies and interstitials in these alloys exhibit a distribution, rather than a single value as in a pure metal or dilute alloy. In this study, using ab initio calculations based on density functional theory and special quasirandom structure, we have characterized the distribution of defect formation energy and migration barrier in four Ni-based solid-solution alloys: Ni_0.5Co_0.5, Ni_0.5Fe_0.5, Ni_0.8Fe_0.2 andmore »« less

Phase stability and thermodynamic database validation in a set of non-equiatomic Al-Co-Cr-Fe-Nb-Ni high-entropy alloys

Journal Article Detrois, Martin ; Antonov, Stoichko ; Tin, Sammy - Intermetallics

A series of six high-entropy alloys in non-equiatomic proportions were produced to study the phase stability across a range of compositions within the Al-Co-Cr-Fe-Nb-Ni system. Phase identification was performed using SEM, TEM, and XRD and computational tools were employed for comparison to the experimental findings. Complex microstructures were obtained following exposure at 900 °C with precipitation of Laves, NiAl, γ' and δ phases. Primary and secondary Laves populations were identified and found to become more stable with increasing Fe and Nb content. Additions of Nb promoted the formation of thin, plate-like, δ phase at the expense of the secondary Laves.more »« less
