Ultrafine-Grained AlCoCrFeNi2.1 Eutectic High-Entropy Alloy
I. S. Wani,Tilak Bhattacharjee,Saad Ahmed Sheikh,Yiping Lu,Subhradeep Chatterjee,Pinaki Prasad Bhattacharjee,Sheng Guo,Nobuhiro Tsuji +7 more
TL;DR: In this paper, the development of microstructure and mechanical properties was investigated in a heavily cold-rolled and annealed AlCoCrFeNi2.1 high-entropy alloy.
Journal ArticleDOI
Alloy design for intrinsically ductile refractory high-entropy alloys
Saad Ahmed Sheikh,Samrand Shafeie,Qiang Hu,Johan Ahlström,Christer Persson,Jaroslav Veselý,Jiří Zýka,Uta Klement,Sheng Guo +8 more
TL;DR: In this article, the authors proposed an alloy design strategy to intrinsically ductilize RHEAs based on the electron theory and more specifically to decrease the number of valence electrons through controlled alloying.
Journal ArticleDOI
Tailoring nanostructures and mechanical properties of AlCoCrFeNi2.1 eutectic high entropy alloy using thermo-mechanical processing
I. S. Wani,Tilak Bhattacharjee,Saad Ahmed Sheikh,Pinaki Prasad Bhattacharjee,Sheng Guo,Nobuhiro Tsuji +5 more
TL;DR: In this paper, the effect of thermo-mechanical processing on the evolution of microstructure and mechanical properties was investigated in an AlCoCrFeNi2.1 high entropy alloy.
Journal ArticleDOI
Simultaneous Strength-Ductility Enhancement of a Nano-Lamellar AlCoCrFeNi2.1 Eutectic High Entropy Alloy by Cryo-Rolling and Annealing
Tilak Bhattacharjee,I. S. Wani,Saad Ahmed Sheikh,Ian Thomas Clark,Toshiro Okawa,Sheng Guo,Pinaki Prasad Bhattacharjee,Nobuhiro Tsuji +7 more
TL;DR: It is demonstrated for the first time that cryo-deformation and annealing could be a novel microstructural design strategy for overcoming strength-ductility trade off in multiphase high entropy alloys.
Journal ArticleDOI
Cold-rolling and recrystallization textures of a nano-lamellar AlCoCrFeNi2.1 eutectic high entropy alloy
I. S. Wani,Tilak Bhattacharjee,Saad Ahmed Sheikh,Ian Thomas Clark,Myeong-heom Park,Toshiro Okawa,Sheng Guo,Pinaki Prasad Bhattacharjee,Nobuhiro Tsuji +8 more
TL;DR: In this article, the development of texture during cold-rolling and recrystallization was investigated in a AlCoCrFeNi2.1 eutectic high entropy alloy (EHEA).
