Effect of valence electron concentration on stability of fcc or bcc phase in high entropy alloys
TL;DR: In this paper, the relationship between phase stability and physicochemical/thermodynamic properties of alloying components in high entropy alloys was studied systematically and the mixing enthalpy was found to be the key factor controlling the formation of solid solutions or compounds.
Journal ArticleDOI
Phase stability in high entropy alloys: Formation of solid-solution phase or amorphous phase
Sheng Guo,C.T. Liu +1 more
TL;DR: In this paper, the atomic size difference, mixing enthalpy, mixing entropy, electronegativity, valence electron concentration among constituent elements in solid solutions forming high entropy alloys and amorphous alloys was analyzed.
Journal ArticleDOI
A Promising New Class of High-Temperature Alloys: Eutectic High-Entropy Alloys
Yiping Lu,Yong Dong,Sheng Guo,Li Jiang,Huijun Kang,Tongmin Wang,Bin Wen,Zhijun Wang,Jinchuan Jie,Zhiqiang Cao,Haihui Ruan,Tingju Li +11 more
TL;DR: A novel strategy to design HEAs using the eutectic alloy concept, i.e. to achieve a microstructure composed of alternating soft fcc and hard bcc phases is proposed, which can be readily adapted to large-scale industrial production of HEAs with simultaneous high fracture strength and high ductility.
Journal ArticleDOI
Directly cast bulk eutectic and near-eutectic high entropy alloys with balanced strength and ductility in a wide temperature range
Yiping Lu,Xuzhou Gao,Li Jiang,Zongning Chen,Tongmin Wang,Jinchuan Jie,Huijun Kang,Yubo Zhang,Sheng Guo,Haihui Ruan,Yonghao Zhao,Zhiqiang Cao,Tingju Li +12 more
TL;DR: In this paper, the deformation behavior and microstructure evolution of the eutectic and near-eUTectic high entropy alloys were thoroughly studied using a combination of techniques, including strain measurement by digital image correlation, in-situ synchrotron X-ray diffraction, and transmission electron microscopy.
Journal ArticleDOI
More than entropy in high-entropy alloys: Forming solid solutions or amorphous phase
TL;DR: In this paper, a two-parameter physical scheme was proposed to capture the phase selection mechanism in high-entropy alloys, where the atomic size polydispersity and mixing enthalpy were taken into account.
