Figure 4
Two exemplary ROIs during in situ loading. ROI 1: Void cluster shown in Fig. 1d illustrating the void growth of several pores (black/blue) for increasing CMOD values within the sample. Further void nucleation occurs due to the cracking of secondary particles (green arrows). Coalescence processes of the voids (red arrows) are leading to crack propagation in the matrix. Due to the complex void-secondary phase particle configuration the segmented volume of ROI 1 only shows the voids in the material. ROI 2: Details of secondary phase particle cracking. The crack initiates at a pre-existing void in the secondary phase particle (white/grey) and subsequently grows with further loading. The blue arrow indicates the direction of crack propagation, the red arrow the direction of the applied force. The segmented volume shows void (blue) and secondary phase particle (grey).
