Predicting the formation and stability of single phase high-entropy alloys
D.J.M. King,D.J.M. King,Simon C. Middleburgh,Simon C. Middleburgh,A.G. McGregor,Michael B. Cortie +5 more
TL;DR: In this article, a method for rapidly predicting the formation and stability of undiscovered single phase high-entropy alloys (SPHEAs) is provided, which uses data for 73 metallic elements and rapidly combines them - 4, 5 or 6 elements at a time - using the Miedema semi-empirical methodology to yield estimates of formation enthalpy.
Journal ArticleDOI
Segregation and migration of species in the CrCoFeNi high entropy alloy
Simon C. Middleburgh,D.J.M. King,D.J.M. King,Gregory R. Lumpkin,Michael B. Cortie,Lyndon Edwards +5 more
TL;DR: In this article, the formation and migration of intrinsic defects in the CrCoFeNi high entropy alloy has been investigated using ab-initio modeling, and the ease of vacancy formation was found to vary depending on the element: vacancies formed by the removal of Fe, Ni and Co are positive while Cr has a negative vacancy formation energy.
Journal ArticleDOI
High temperature, low neutron cross-section high-entropy alloys in the Nb-Ti-V-Zr system
D.J.M. King,D.J.M. King,S.T.Y. Cheung,Samuel A. Humphry-Baker,Calvin Parkin,Adrien Couet,Michael B. Cortie,Gregory R. Lumpkin,Simon C. Middleburgh,Alexander J. Knowles,Alexander J. Knowles +10 more
TL;DR: In this article, a recently developed high throughput computational screening tool Alloy Search and Predict (ASAP) was used to identify the most likely candidate single-phase HEAs with low thermal neutron cross-section, from over a million four-element equimolar combinations.
Journal ArticleDOI
Predicting the Crystal Structure and Phase Transitions in High-Entropy Alloys
D.J.M. King,D.J.M. King,Simon C. Middleburgh,Simon C. Middleburgh,Lyndon Edwards,Gregory R. Lumpkin,Michael B. Cortie +6 more
TL;DR: In this paper, the authors investigated the transition between a face-centered cubic (FCC) and a body-centred cubic (BCC) structure in a high-entropy alloy system and found that an ordered lattice is favored over a truly random lattice.
Journal ArticleDOI
Cr-Mo-V-W: A new refractory and transition metal high-entropy alloy system
D. Ikeuchi,D.J.M. King,Kevin J. Laws,Alexander J. Knowles,R.D. Aughterson,Gregory R. Lumpkin,E.G. Obbard,E.G. Obbard +7 more
TL;DR: CrMo-V-W high-entropy Alloy Search and Predict (ASAP) and phase diagram calculations found a single phase, body-centred cubic (BCC) solid solution at elevated temperatures, across the range of compositions present within the system - uncommon for a HEA of refractory and transition metals as discussed by the authors.
