Enhanced Plasticity of Bulk MetalLic Glass Alloys (BMGs) by Internal Microstructural Modification

As a new emerging field of materials, bulk metallic glasses (BMGs) have received particular attention due to their high glass forming ability, desirable mechanical and chemical properties. However, the drawback of BMGs is their limited global room temperature plasticity that severely impedes further applications of this material. Therefore, possible methods of enhancing plasticity have emerged from extensive studies of the deformation of metallic glasses in compression, including introduction of second ductile crystalline phase, phase separation and nanocrystallization.
