Figure 1. Correlation between the ΔH_des of single-phase BCC alloys reported in the literature and (A) lattice constants, (B) δ, (C) corresponding alloy composition, (D) VEC, and (E) EDV_alloy; (F) design strategy. The linear fitting results, including R² and P-values, are shown in the corresponding panels. VEC: Valence electron concentration; ΔH_des: desorption enthalpy; EDV_alloy: electronegativity difference value of the alloy; HEA: high-entropy alloy; δ: lattice distortion; BCC: body-centered cubic.
