Alloying behavior in multi-component AlCoCrCuFe and NiCoCrCuFe high entropy alloys
TL;DR: In this article, alloying behavior was investigated using XRD in AlCoCrCuFe and NiCoCrcuFe equi-atomic high entropy alloys synthesized by mechanical alloying (MA) and spark plasma sintering (SPS).
Journal ArticleDOI
Alloying, thermal stability and strengthening in spark plasma sintered AlxCoCrCuFeNi high entropy alloys
TL;DR: In this paper, the thermal stability studies carried out in the temperature range of 400-600°C for duration of 2-10h in Ar atmosphere suggest that these alloys exhibit excellent thermal stability in terms of phases and crystallite size.
Journal ArticleDOI
Thermal stability and grain boundary strengthening in ultrafine-grained CoCrFeNi high entropy alloy composite
Praveen Sathiyamoorthi,Joysurya Basu,Sanjay Kashyap,Konda Gokuldoss Pradeep,Ravi Sankar Kottada +4 more
TL;DR: In this paper, the thermal stability of CoCrFeNi high entropy alloy in as-milled and sintered conditions was investigated using X-ray diffraction, differential scanning calorimetry, transmission electron microscopy, and atom probe tomography.
Journal ArticleDOI
Exceptional resistance to grain growth in nanocrystalline CoCrFeNi high entropy alloy at high homologous temperatures
TL;DR: In this article, Nanocrystalline CoCrFeNi high entropy alloy, synthesized by mechanical alloying followed by spark plasma sintering, demonstrated extremely sluggish grain growth even at very high homologous temperature of 0.68 t m (900 °C) for annealing duration of 600h.
Journal ArticleDOI
Plasma-Sprayed High Entropy Alloys: Microstructure and Properties of AlCoCrFeNi and MnCoCrFeNi
