Indentations on the β-HMX crystal habit faces. {010} Face: (a) Knoop, long diagonal parallel to [100] (Ref.); (b) Knoop, long diagonal parallel to \( \left[10\overline{1}\right] \) (Ref.); (c) Knoop, long diagonal normal to \( \left[10\overline{1}\right] \) (Ref.); (d) Knoop, long diagonal normal to \( \left[10\overline{1}\right] \) (Trans). {011} Face; (e) Vickers, diagonal 45° to [100] (Trans); (f) Knoop, normal to [100] (Ref); (g) Knoop, normal to [100] ((f) in Trans). {110} Face: (h) Vickers, diagonal parallel to [001] (Ref); (i) Knoop normal to [001] (Ref); (j) Knoop, long diagonal 65° to [001] (Ref); (k) Knoop parallel to [001] (Ref). S = Slip traces, T = twin bands, C = cracking, (Ref.) and (Trans.) = reflection or transmission photomicrograph.
