نویسندگان
چکیده
A carbon-containing CoCrFeNi high entropy alloy (HEA) with heterogeneous structures was obtained through thermomechanical treatments, which induced concurrent recrystallization and carbide precipitation in the alloy. combination of yield strength (556 MPa) large uniform elongation (45%) achieved investigated The enhancement is attributed to combined effects grain refinement, strengthening microstructural heterogeneity. Our work demonstrated that heterogeneity design could be realized by processes, provided a practical strategy for producing HEAs performance.

Polymorphism in a high-entropy alloy
Polymorphism, which describes the occurrence of different lattice structures in a crystalline material, is a critical phenomenon in materials science and condensed matter physics. Recently, configuration disorder was compositionally engineered into single lattices, leading to the discovery of high-entropy alloys and high-entropy oxides. For these novel entropy-stabilized forms of crystalline ma...

High-entropy (H-E) alloys, bulk metallic glasses (BMGs) and high-entropy BMGs (HE-BMGs) were statistically analyzed with the help of a database of ternary amorphous alloys. Thermodynamic quantities corresponding to heat of mixing and atomic size differences were calculated as a function of composition of the multicomponent alloys. Actual calculations were performed for configurational entropy (...

Guided by CALPHAD (Calculation of Phase Diagrams) modeling, the refractory medium-entropy alloy MoNbTaV was synthesized by vacuum arc melting under a high-purity argon atmosphere. A body-centered cubic solid solution phase was experimentally confirmed in the as-cast ingot using X-ray diffraction and scanning electron microscopy. The measured lattice parameter of the alloy (3.208 Å) obeys the ru...
متن کاملThermal stability of AlCoCrCuFeNi high entropy alloy thin films
High entropy alloys (HEAs), containing five to thirteen metallic elements, with a concentration in the range of 5 to 35 % for each element, exhibit very interesting properties (mechanical, tribological, formability, magnetism...). Their high mixing entropy promotes the formation of simple solid solutions with amorphous or nanocrystallized structure. Bulk pieces of these alloys are known to be s...
متن کاملHigh-velocity deformation of Al0.3CoCrFeNi high-entropy alloy: Remarkable resistance to shear failure
The mechanical behavior of a single phase (fcc) Al0.3CoCrFeNi 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 dy...
