Journal ArticleDOI
Deviation from high-entropy configurations in the atomic distributions of a multi-principal-element alloy
Louis J. Santodonato,Yang Zhang,Mikhail Feygenson,Chad M. Parish,Michael C. Gao,Richard Weber,Joerg C. Neuefeind,Z. Tang,Peter K. Liaw +8 more
TL;DR: It is shown that, even when the material undergoes elemental segregation, precipitation, chemical ordering and spinodal decomposition, a significant amount of disorder remains, due to the distributions of multiple elements in the major phases.
Journal ArticleDOI
Tensile ductility of an AlCoCrFeNi multi-phase high-entropy alloy through hot isostatic pressing (HIP) and homogenization
Z. Tang,Z. Tang,Oleg N. Senkov,Chad M. Parish,Chuan Zhang,Fan Zhang,Louis J. Santodonato,Louis J. Santodonato,Gongyao Wang,Guangfeng Zhao,Fuqian Yang,Peter K. Liaw +11 more
TL;DR: In this article, the microstructure and phase composition of an AlCoCrFeNi high-entropy alloy (HEA) were studied in as-cast and homogenized conditions.
Journal ArticleDOI
Chemical short-range orders and the induced structural transition in high-entropy alloys
Yue Ma,Qing Wang,Chunling Li,Louis J. Santodonato,Mikhail Feygenson,Mikhail Feygenson,Chuang Dong,Peter K. Liaw +7 more
TL;DR: In this paper, the existence of chemical short-range orders (CSROs) in high-entropy alloys (HEAs) using a cluster-plus-glue-atom model was verified.
Journal ArticleDOI
Predictive multiphase evolution in Al-containing high-entropy alloys
Louis J. Santodonato,Peter K. Liaw,Raymond R. Unocic,Hongbin Bei,James R. Morris,James R. Morris +5 more
TL;DR: An approach where parameters from first principle simulations are incorporated into Monte Carlo simulations to reproduce phase evolution of aluminium-containing high entropy alloys is developed.
Journal ArticleDOI
Rapid imbibition of water in fractures within unsaturated sedimentary rock
Chu-Lin Cheng,Edmund Perfect,B. Donnelly,Hassina Z. Bilheux,Anton S. Tremsin,Larry D. McKay,Victoria H. DiStefano,Victoria H. DiStefano,Jianchao Cai,Louis J. Santodonato +9 more
TL;DR: In this article, a theoretical framework for predicting the 1-dimensional movement of water into air-filled fractures within a porous medium based on early-time capillary dynamics and spreading over the rough surfaces of fracture faces is presented.
