A shock wave traveling through a material can create defects known as dislocations – tiny shifts in the material’s crystal that propagate through it, leaving what are known as stacking faults behind.
Understanding how dislocations (line defects in the crystal structure) occur when 3D-printing metals has been unclear to materials scientists. Understanding when and how dislocations form in ...
Plastic deformation of materials is caused by nucleation and multiplication of dislocations under an external force (A and B). It is generally believed that brittle inorganic semiconducting materials ...
