Pham and colleagues created a lattice superstructure with multiple crystal interfaces that exhibited similar shear-banding behavior to metallurgical crystal twins. Lu and team studied the hardening principle of inclusions and the strengthening mechanism of dual phase lattice structures, enabling control over the deformation pattern and damage mechanism. Researchers have improved properties by altering crystal interfaces, introducing nanocrystals, using contact between adjacent member elements, introducing holes, and analyzing defect types. These failure mechanisms inform the design of new lattice structures with better mechanical properties.
