Title: Peierls barrier characteristic and anomalous strain hardening provoked by dynamic-strain-aging strengthening in a body-centered-cubic high-entropy alloy

Abstract

The temperature effect on the mechanical behavior of the HfNbTaTiZr high entropy alloy (HEA) was investigated at 77–673 K. The decrease of the yield strength with increasing the temperature was mechanistically analyzed by considering contributions from various strengthening mechanisms. An anomalous dependence of strain hardening on temperature was observed and was justified to be caused by dynamic strain aging (DSA) as an extra strengthening mechanism at elevated temperatures. A model was constructed to split the overall strain hardening into forest hardening and DSA hardening, both of which were theoretically quantified at all temperatures considered. The work quantifies the height of Peierls barriers in the bcc HfNbTaTiZr HEA, and reveals dynamic strain aging as the strengthening mechanism causing the anomalous strain hardening at elevated temperatures.

Creep and low-cycle fatigue behavior of ferritic Fe-24Cr-4Al alloy in the dynamic strain aging regime: Effect of aluminum addition

Journal Article Tjong, S C ; Zhu, S M - Metallurgical and Materials Transactions. A, Physical Metallurgy and Materials Science

Creep and low-cycle fatigue behavior of ferritic Fe-24Cr-04Al alloy was studied in the temperature range of 673 to 873 K, where dynamic strain aging (DSA) occurrence was found. The DSA of the alloy manifested in the form of serrated flow, negative strain rate sensitivity, and the peak or plateau in the variations of yield strength (YS) and ultimate tensile strength (UTS) with temperature. The characteristic creep behavior of the alloy was experimentally verified as that for a class I solid solution. However, this ferritic alloy showed an anomalous high stress exponent (n = 5.7) and high activation energy (Q{sub c}more »« less

The influence of dynamic strain ageing on stress response and strain-life relationship in low cycle fatigue of 316L(N) stainless steel

Journal Article Srinivasan, V S ; Sandhya, R ; Valsan, M ; ... - Scripta Materialia

It has been recognized that the essential prerequisite for accurate prediction of low cycle fatigue life (LCF) at elevated temperatures is the determination of rate controlling time dependent damage process that influences the cyclic deformation and fracture behavior of alloys. At intermediate temperatures (0.25 < T/T{sub m} < 0.55, where T{sub m} is melting point in Kelvin), where the effects of time dependent processes such as creep and oxidation are found to be minimal, the drastic reduction in low cycle fatigue life observed with increasing temperature and decreasing strain rate in alloys such as type 04 stainless steel, Nimonic PEmore »« less

Manifestations of dynamic strain aging in soft-oriented NiAl single crystals

Journal Article Weaver, M L ; Kaufman, M J ; Noebe, R D - Metallurgical and Materials Transactions. A, Physical Metallurgy and Materials Science

The tensile and compressive properties of six NiAl-base single-crystal alloys have been investigated at temperatures between 77 and 1,200 K. The normalized critical resolved shear stresses (CRSS/E) and work-hardening rates ({theta}/E) for these alloys generally decreased with increasing temperature. However, anomalous peaks or plateaus for these properties were observed in conventional purity (CPNiAl), Si-doped (NiAl-Si), C-doped low Si (UF-NiAl1), and Mo-doped (NiAl-Mo) alloys at intermediate temperatures (600 to 1,000 K). This anomalous behavior was not observed in high-purity, low interstitial material (HP-NiAl). Low or negative strain-rate sensitivities (SRS) also were observed in all six alloys in this intermediate temperature range.more »« less

Mechanical behavior and shear band of a powder-metallurgy-fabricated CoCrFeMnNi high-entropy alloy during high strain-rate deformation

Journal Article Li, Wenshu ; Wang, Bingfeng ; Huang, Xiaoxia ; ... - Journal of Materials Research and Technology

High-entropy alloys (HEAs) fabricated by powder metallurgy are considered to exhibit extremely-great potential application values in the field for high-speed impact deformation due to their uniform microstructures and compositions. The mechanical behavior of a powder-metallurgy-fabricated (PM) CoCrFeMnNi HEA was investigated at room temperature with strain rates ranging from 1200 s^-1 to 2800 s^-1. It was found that the serration behavior and shear localization of the alloy under dynamic conditions occurred. Results also indicated that the serrated flow took place in the PM CoCrFeMnNi HEA during mechanical deformation at high strain rates (>1000 s^-1) and became more pronounced as the strain rate increased. Furthermore, it was determined that the yield-strength values of the PM CoCrFeMnNi HEA were sensitive to strain rates, where the values increased from 500 MPa to 700 MPa when the strain rates increased from 1200 s^-1 to 2800 s^-1. Shear bands with a width of about 20 μm were generated in the PM CoCrFeMnNi HEA after the shear stress reached a maximum value of 635 MPa, which corresponded to a nominal strain of about 8.71. Nanotwins and ultrafine-equiaxed grains with a diameter of about 150 nm also developed at the core of the shear band during deformation. The results revealed that the strength of the shear band was much higher than that of the matrix grain. Nanotwins in the shear band were composed of a single face-centered-cubic (FCC) structure with the twin plane of (more »« less

Effects of transient thermal shock on the microstructures and corrosion properties of a reduced activation high-entropy alloy

Journal Article Zhang, Wei-Ran ; Liao, Wei-Bing ; Liaw, Peter K. ; ... - Journal of Alloys and Compounds

The devices would subject transient thermal shocks (TTS) during operation under extremely harsh conditions of nuclear fusion reactors, which inevitably exert significant impact on the microstructure and performance of structural materials. Here, a reduced activation VCrFeTa_0.2W_0.2 high-entropy alloy (HEA) was developed by vacuum arc melting. The effects of electron beam induced TTS on its microstructure, microhardness, and corrosion properties were investigated. The results indicate that the weight fraction of each phase changes after TTS, showing a significant decrease in the content of BCC1 phase and an increase in the content of BCC2 and Laves phases.
