Figure 5: Mechanism of transgranular liquation cracking.
From: Transgranular liquation cracking of grains in the semi-solid state
(a–d) 2D schematic of the four stages: (a) motion and pinning of grains resulting in compressive and shear loads; (b) straining and dislocation movement under a stress state; (c) possible remelting and interface perturbation (shown for only one contact); and (d) crack growth from the surface of the grain accelerated by liquid entrainment. (e–h) Region of interest from Fig. 1b–e (yellow dotted circle) where transgranular fracture of single-crystal grains is occurring. Scale bar, 150 μm.
