Fig. 3. Specimen geometry and locations of histocompositional analyses. (A) Tension (dumbbell-shaped) and (B) compression (cubic) specimens. In (C) the hatched areas indicate the locations where fragments were obtained for microstructural, CFO and % ash analyses. BSE denotes that backscattered electron imaging was used for analysis of microstructure. % Ash was determined on 50-70% of the portion labeled `% ash' and indicated by the non-bolded hatched lines.
