Hello I prepared an equiatomic FeCoNiAlMn High entropy alloy powder produced by mechanical alloying of 45hrs using Ball mill. I am not getting that among Cr, V and Sn which element can replace in equi-atomic FeCoNiAlMn for enhancing soft magnetic properties of high entropy alloy powder.
@Mohammad Afikizzaman but Cr is anti-ferromagnetic so if I replace Mn which is paramagnetic with anti-ferromagnetic Cr so will it enhance soft magnetic properties of equi-atomic High Entropy Alloys Powder Produced by Mechanical Alloying
Dear Siddiqui,
As per my understanding, the Cr element is the best substitution element among Cr, V and Sn to enhance the magnetic properties and mechanical properties in HEAs. For example, the AlCoCrFeNiTi HEA system is the most promising alloy that exhibits excellent mechanical properties and structural stability at elevated temperatures might be enhancing magnetic properties as well.

I hope this (answer) helps you.
Good Luck!
Hello Danial
A major problem with mechanical alloying is the impurities oxides that form during milling, which would not result in the desired microstructure.
I hope you are doing a detailed characterization to see the oxide formation during milling. Additionally, if you use inert atmosphere or wet milling, oxide formation cannot be avoided.
