Fig. 7.. (a) Comparison between σ-ε curve of diamond/lonsdaleite biphases and those of diamond sheared along ESD and along HSD under σzz = 200 GPa; (b) comparison between σ-ε curve of cBN/wBN biphases and those of cBN sheared along ESD and along HSD under σzz = 200 GPa; (c)-(g) structural snapshots of (3 + 1)L + D at ε0 = 0, ε1 = 0.22, ε2 = 0.23, ε3 = 0.30, and ε4 = 0.31, respectively, with yellow regions denoting lonsdaleite (Lon) regions and b denoting Burgers vector a0/6 [112ˉ].
