Tungsten-containing high-entropy alloys: a focused review of ...

Apr 23, 2021The exploitation of conventional W-based alloy is restricted to the corner of multielement phase diagrams with tiny compositional space. High-entropy alloys (HEAs) are a novel kind of alloys consisting of multi-principal alloying elements (usually more than 4) and have attracted increasing attention, since they were first reported in 2004.

Microstructure and magnetic behavior of FeCoNi(Mn-Si)x (x = 0.5, 0.75 ...

It can be concluded that after 5 h of milling, the rate of diffusion of Mn ( r a = 0.161 nm) and Fe ( r a = 0.126 nm) into Ni ( r a = 0.124 nm) lattice becomes more prominent and thus slightly increases the lattice parameter of Ni. For FeCoNi (Mn-Si) 1.0, the lattice parameter after 25 h milling is 0.3565 nm (0.3565: PDF card no-01-089-7128).
