From: Tailored hardening of ZrCuAl bulk metallic glass induced by 2D gradient rejuvenation
a1 Schematic diagram of propagation of the shear band initiated from the slow-cooled surface. a2, a3 Schematic diagram of initiation of new shear bands and the subsequent hardening mechanism. b1 Schematic diagram of blockage of the shear band initiated from the fast-cooled surface. b2, b3 Schematic diagram of initiation of new shear bands, propagation of the shear band initiated from the fast-cooled surface, and the subsequent hardening mechanism.
