Accelerated and conventional development of magnetic high entropy alloys

Highly complex magnetic behavior resulting from hierarchical phase separation in AlCo(Cr)FeNi high-entropy alloys

“…The HEAs are almost fully magnetically saturated at fields of 500 mT. Figure 1 B shows a comparison of M S and H C for AlCoFeNi and AlCo 0.5 Cr 0.5 FeNi HEAs with other HEAs and benchmark soft magnetic materials ( Borkar et al., 2017 ; Chaudhary et al., 2021 ; Dasari et al., 2020 ; Li et al., 2017 ; Zhang et al., 2013 ). The magnetic properties of the HEAs that we have studied are similar to others.…”

Performance-oriented multistage design for multi-principal element alloys with low cost yet high efficiency

“…3D) illustrates that the weight coefficient of the VEC to decide the phase structure gradually declines, accompanied by the increase of the weight coefficient of the mixing enthalpy, which breaks the traditional rule of VEC acting as only the high impact feature. 25,26 Hence, the formation mechanism of multi-phases is extremely complex, and this result gives avenues towards the multi-mechanism criterion that beats the single rule for precise structural design.…”

A Focused Review on Engineering Application of Multi-Principal Element Alloy

“…Furthermore, a combinatorial computational method is proposed to develop the new magnetic MPEAs. High-throughput method is utilized to screen out promising magnetic MPEAs, and then machine learning, additive manufacturing and CALPHAD methods are used to further predict the magnetic property (Chaudhary et al, 2021). Using DFT calculation and machine learning, *OH and *O adsorption energies on the surface of IrPdPtRhRu MPEA can be accurately predicted, which provids a useful strategy to discover the new MPEAs with outstanding catalytic activity (Batchelor et al, 2019).…”
