In Situ Atomistic Deformation Mechanisms Study of Nanowires

摘要: “Smaller is stronger,” sub-, micro-, and nanomaterials exhibit high strength, ultralarge elasticity unusual plastic fracture behaviors which originate from their size effect the low density of defects, different conventional bulk counterparts. To understand structural evolution process under external stress at atomic scale crucial for us to reveal essence these “unusual” phenomena momentous in design new materials. Our review presents recent developments methods, techniques, instrumentation, scientific progress situ deformation dynamics on single crystalline nanowires. The super-large elasticity, mechanism transmission, behavior related experimental mechanics are reviewed. In open a research field important not only microscopic methodology but also practice.
