Figure 6. (A) The concentration profile of W (R_W) and Ti (R_Ti) at the metallic site surrounding various grain boundaries, displaying prominent W segregation around these boundaries, which results in Ti depletion around these boundaries. The unit of the horizontal axis is Å; (B) A comparison of the ideal grain boundary strength between pure Ti_1/3Zr_1/3Hf_1/3B₂ (ME-TMB₂) and Ti_1/3Zr_1/3Hf_1/3B₂ with W segregation. Ideal grain boundary strength values are listed in Supplementary Table 3.
