Journal ArticleDOI
The influences of temperature and microstructure on the tensile properties of a CoCrFeMnNi high-entropy alloy
F. Otto,F. Otto,Antonín Dlouhý,Christoph Somsen,Hongbin Bei,Gunther Eggeler,Easo P. George,Easo P. George +7 more
TL;DR: In this article, an equiatomic CoCrFeMnNi high-entropy alloy, which crystallizes in the face-centered cubic (fcc) crystal structure, was produced by arc melting and drop casting.
Journal ArticleDOI
Relative effects of enthalpy and entropy on the phase stability of equiatomic high-entropy alloys
TL;DR: In this paper, the authors evaluate the usefulness of configurational entropy as a predictor of single-phase stability in equiatomic, quinary alloys by replacing individual elements one at a time in a CoCrFeMnNi alloy.
Journal ArticleDOI
Recovery, recrystallization, grain growth and phase stability of a family of FCC-structured multi-component equiatomic solid solution alloys
Zhenggang Wu,Hongbin Bei,F. Otto,F. Otto,George M. Pharr,George M. Pharr,Easo P. George,Easo P. George +7 more
TL;DR: In this article, the authors investigated various binary, ternary and quaternary alloys made from the equiatomic high-entropy alloy FeNiCoCrMn.
Journal ArticleDOI
Decomposition of the single-phase high-entropy alloy CrMnFeCoNi after prolonged anneals at intermediate temperatures
F. Otto,Antonín Dlouhý,Konda Gokuldoss Pradeep,Monika Kuběnová,Dierk Raabe,Gunther Eggeler,Easo P. George +6 more
TL;DR: In this article, the authors evaluated the phase stability of CrMnFeCoNi and showed that it is a single-phase solid solution after homogenization for 2 days at 1200°C and remains in this state after a subsequent anneal at 900°C for 500 days.
Journal ArticleDOI
Temperature dependencies of the elastic moduli and thermal expansion coefficient of an equiatomic, single-phase CoCrFeMnNi high-entropy alloy
Guillaume Laplanche,Pascal Gadaud,O. Horst,F. Otto,Gunther Eggeler,Easo P. George,Easo P. George +6 more
TL;DR: In this paper, the authors measured the temperature dependencies of elastic moduli and thermal expansion coefficient of the CoCrFeMnNi alloy over a large temperature range (200 −1270 K).
