Title: Phase transformations of HfNbTaTiZr high-entropy alloy at intermediate temperatures

Abstract

The strong and ductile single-phase body-centered-cubic (BCC) HfNbTaTiZr refractory high-entropy alloy (RHEA) is a potential structural material for high-temperature applications. However, the BCC phase stability in the intermediate temperature range (500–900 °C) needs to be better understood to make this alloy applicable to industry. In the present work, the phase decomposition of the HfNbTaTiZr RHEA is examined at different temperatures (500–1000 °C). Additionally, the formation of BCC Ta-Nb-rich and hexagonal-close-packed (HCP) Hf-Zr-rich precipitates are studied as a function of annealing time at 700 °C using a combination of atom probe tomography, transmission electron microscopy, and X-ray diffraction. We found that these BCC and HCP precipitates have preferred orientations with the BCC matrix.

Computational exploration of biomedical HfNbTaTiZr and Hf_0.5Nb_0.5Ta_0.5Ti_1.5Zr refractory high-entropy alloys

Journal Article Bhandari, Uttam ; Ghadimi, Hamed ; Zhang, Congyan ; ... - Materials Research Express (Online)

Refractory high entropy alloys (RHEAs) have been proven to be a potential candidate in the biomedical field due to their balanced mechanical properties and biocompatible composition. Recent experimental findings show that RHEAs like HfNbTaTiZr and Hf_0.5Nb_0.5Ta_0.5Ti_1.5Zr have good mechanical properties such as high polarization and wear resistance than others which establish them as potential materials for biomedical application. In this work, we performed first-principles density functional theory calculations on the mechanical and thermal properties of HfNbTaTiZr and Hf_0.5Nb_0.5Ta_0.5Ti_1.5Zr. The predicted lattice constant, density, Young's modulus, and Vickers hardness are consistent with the available experimental report, which verifies the accuracy ofmore »« less

Investigation of phase-transformation path in TiZrHf(VNbTa)x refractory high-entropy alloys and its effect on mechanical property

Journal Article Jung, Yunjong ; Lee, Kangjin ; Hong, Soon Jik ; ... - Journal of Alloys and Compounds

Refractory high-entropy alloys (RHEAs) show a great potential as structural materials due to their remarkable properties, such as high strength and thermal stability. Despite these advantages, the RHEAs still suffer from the limited ductility at room temperature. To overcome the strength-ductility trade-off, the new RHEA design strategy, transformation-induced plasticity (TRIP) HEAs, have been developed by applying metastability-engineering approach. With the newly developed RHEAs design strategy, we designed metastable RHEAs, TiZrHfVxNbxTax (x = 1.0, 0.5 and 0.1) with decrease of the β-stabilizing elements (V, Nb, and Ta) to promote the transformation-induced ductility and work-hardening capability. The proper addition of the β-stabilizingmore »« less

Phase stability and transformation in a light-weight high-entropy alloy

Journal Article Feng, Rui ; Gao, Michael C. ; Zhang, Chuan ; ... - Acta Materialia

Light-weight high-entropy alloys (HEAs) with a vast alloy-design space have offered new avenues to explore novel low-cost, high strength-to-weight ratio structural materials. Studying their phase stability and possible transformations is critical for designing microstructures for optimal material properties. However, the complex local atomic environment of HEAs poses challenges to the fundamental understanding of phase stability and transformation behaviors. The present paper investigates the phase stability and transformation behaviors of a newly-designed light-weight Al_1.5CrFeMnTi HEA by integrated experimental and theoretical approaches. The coherent precipitation of the L2₁ phase within the body-centered-cubic (BCC) matrix at intermediate temperatures was observed, and the size,more »« less

Grain growth and Hall-Petch relationship in a refractory HfNbTaZrTi high-entropy alloy

Journal Article Chen, Shuying ; Tseng, Ko-Kai ; Tong, Yang ; ... - Journal of Alloys and Compounds

Understanding the effect of temperature variation on the microstructural evolution is particularly important to refractory high-entropy alloys (RHEAs), given their potential high-temperature applications. Here, we experimentally investigated the grain-growth behavior of the HfNbTaZrTi RHEAs during recrystallization at temperatures from 1,000 to 1,200 °C for varied durations, following cold rolling with a 70% thickness reduction. Following the classical grain-growth kinetics analysis, two activation energies are obtained: 205 kJ/mol between 1,000 and 1,100 °C, and 401 kJ/mol between 1,100 and 1,200 °C, which suggests two mechanisms of grain growth. Moreover, the yield strength – grain size relation was found to be wellmore »« less

Tailoring magnetic behavior of CoFeMnNiX (X = Al, Cr, Ga, and Sn) high entropy alloys by metal doping

Journal Article Zuo, Tingting ; Gao, Michael C. ; Ouyang, Lizhi ; ... - Acta Materialia

Magnetic materials with excellent performances are desired for functional applications. Based on the high-entropy effect, a system of CoFeMnNiX (X = Al, Cr, Ga, and Sn) magnetic alloys are designed and investigated. The dramatic change in phase structures from face-centered-cubic (FCC) to ordered body-centered-cubic (BCC) phases, caused by adding Al, Ga, and Sn in CoFeMnNiX alloys, originates from the potent short-range chemical order in the liquid state predicted by ab initio molecular dynamics (AIMD) simulations. This phase transition leads to the significant enhancement of the saturation magnetization (M_s), e.g., the CoFeMnNiAl alloy has M_s of 147.86 Am²/kg. In conclusion, first-principlesmore »« less
