High Strength Refractory AlHfNbTiV B2 High Entropy Alloys with High Fracture Strains
Jie Qi, Xuesong Fan, Diego Ibarra Hoyos +2
We demonstrate the development of a series of refractory high-entropy alloys containing aluminum AlRHEAs in the ordered BCC-B2 phase by varying the aluminum content within 10 to 25…
Yield Strength-Plasticity Trade-Off and Uncertainty Quantification for Machine-learning-based Design of Refractory High-Entropy Alloys
Stephen A. Giles, Hugh Shortt, Peter K. Liaw +1
Development of process-structure-property relationships in materials science is an important and challenging frontier which promises improved materials and reduced time and cost in…
Chemical Short-Range Ordering in a CrCoNi Medium-Entropy Alloy
H. W. Hsiao, R. Feng, H. Ni +4
The exceptional mechanical strengths of medium and high-entropy alloys have been attributed to hardening in random solid solutions. Here, we evidence non-random chemical mixings in…
Pseudoelastic deformation in Mo-based refractory multi-principal element alloys
Aayush Sharma, Prashant Singh, Tanner Kirk +5
Phase diagrams supported by density functional theory methods can be crucial for designing high-entropy alloys that are subset of multi-principalelement alloys. We present phase…
The Serrated-Flow Behavior in High-Entropy Alloys
Jamieson Brechtl, Peter K. Liaw
This chapter presents a literature review of the serrated flow phenomenon in high-entropy alloys (HEAs). The serrated flow is important as it can result in permanent macroscopic an…
Charge-transfer effect on local lattice distortion in a HfNbTiZr high entropy alloy
Fanchao Meng, Wenyan Zhang, Zhukun Zhou +12
It is often assumed that atoms are hard spheres in the estimation of local lattice distortion (LLD) in high-entropy alloys (HEAs). However, our study demonstrates that the hard sph…
Mechanical behavior of high-entropy alloys: A review
Yuanyuan Shang, Jamieson Brechtl, Claudio Psitidda +1
High-entropy alloys (HEAs) are materials that consist of equimolar or near-equimolar multiple principal components but tend to form single phases, which is a new research topic in…
Materials Fingerprinting Classification
Adam Spannaus, Kody J. H. Law, Piotr Luszczek +6
Significant progress in many classes of materials could be made with the availability of experimentally-derived large datasets composed of atomic identities and three-dimensional c…
Machine Learning and Data Analytics for Design and Manufacturing of High-Entropy Materials Exhibiting Mechanical or Fatigue Properties of Interest
Baldur Steingrimsson, Xuesong Fan, Anand Kulkarni +2
This chapter presents an innovative framework for the application of machine learning and data analytics for the identification of alloys or composites exhibiting certain desired p…
Edge Dislocations Can Control Yield Strength in Refractory Body-Centered-Cubic High Entropy Alloys
Francesco Maresca, Chanho Lee, Rui Feng +8
Energy efficiency is motivating the search for new high-temperature metals. Some new body-centered-cubic random multicomponent "high entropy alloys (HEAs)" based on refractory elem…
On the Study of Chaos and Memory Effects in the Bonhoeffer-van der Pol Oscillator with a Non-Ideal Capacitor
Jamieson Brechtl, Xie Xie, Karin A. Dahmen +2
In this paper, the voltage fluctuations of the Bonhoeffer van der pol oscillator system with a non-ideal capacitor were investigated. Here, the capacitor was modeled, using a fract…
Complexity Analysis of Chaos and Other Fluctuating Phenomena
Jamieson Brechtl, Xie Xie, Karen A. Dahmen +1
The refined composite multiscale-entropy algorithm was applied to the time-dependent behavior of the Weierstrass functions, colored noise, and Logistic map to provide fresh insight…
First-principles prediction of high-entropy-alloy stability
Rui Feng, Peter K. Liaw, Michael C. Gao +1
High entropy alloys (HEAs) are multicomponent compounds whose high configurational entropy allows them to solidify into a single phase, with a simple crystal lattice structure. Som…
