Fig. 3: Rate-dependent void distributions underneath the spall fracture surface.
From: Amorphous alloys surpass E/10 strength limit at extreme strain rates

SEM micrographs on the sidewall of the well milled by FIB show void growth and coalescence underneath the spall planes for the sample tested by the laser with 2.5 ns pulse duration and 5.0 J energy (a) and the laser with 1 ns pulse duration and 8.4 J energy (b).
