(a–f) shows fractographies of as-cast and Cu/Ni-coated Ni54Nb42Al4 MG fibers. (a) As-cast Ni-Nb-Al MG fiber shows generation of few vein patterns on fracture surface, (b) As-cast MG fiber shows single shear band on fracture surface (c) and (d) shows bilayered Cu/Ni-coated Ni54Nb42Al4 MG fiber with dense vein patterns on fracture surfaces, (e) & (f) shows dense vein patterns changes into viscous fingering with R = 85% on fracture surface of Cu/Ni-coated MG fibers. (g) shows transition of viscous fingering into dimples, (h) Shows shear bands on side surface of Cu/Ni-electrodeposited Ni54Nb42Al4 fiber.
