| Abstract Scope |
Intermetallics have drawn considerable attention in developing novel metallic materials for various applications due to their high strength and high melting points. Nonetheless, the susceptibility to brittle fracture at room temperatures severely limit their practical applications. Here, we report the microstructure and mechanical behavior of nanocrystalline intermetallics. In situ SEM micropillar compression studies show that these intermetallics exhibits ultrahigh flow stress along with prominent work hardening ability. Post-deformation transmission electron microscopy coupled with molecular dynamics (MD) simulations reveal the origin of plasticity and work hardening. This study provides a new perspective to enhance the room temperature plasticity of brittle intermetallics. |
