| Abstract Scope |
This presentation demonstrates how to create various heterogeneous and adaptive microstructures by defect engineering for controlled strain release during elastic and plastic deformations. Compositional and/or structural non-uniformities engineered through various non-conventional phase transformation pathways, thermomechanical processes, and novel processing methods such as 3D-printing are shown to have the ability to activate different elastic and plastic deformation mechanisms (including intrinsic elasticity and pseudo-elasticity, and dislocation plasticity and transformation plasticity) at different stages of deformation, offering well-controlled strain release and exceptional mechanical properties including linear superelasticity, ultralow elastic modulus, and an excellent combination of strength, ductility and work-hardening ability. Structural heterogeneities created during deformation could be coupled with localized phase transformations that act as a self-healing mechanism, offering an outstanding creep resistance. |
