Nanocrystallization at shear bands in bulk metallic glass matrix composites

We investigated the effect of reinforcement on the formation of nanocrystals at shear bands in a Ni-based metallic glass matrix composite in comparison with monolithic Ni-based bulk metallic glass when shear bands are generated during deformation. The results suggest that the occurrence of nanocryst...

description We investigated the effect of reinforcement on the formation of nanocrystals at shear bands in a Ni-based metallic glass matrix composite in comparison with monolithic Ni-based bulk metallic glass when shear bands are generated during deformation. The results suggest that the occurrence of nanocrystallization at a shear band implies a stress concentration by a geometrical effect of the reinforcement phase on the compressive loading conditions.
