| Abstract Scope |
Dislocations in crystalline solids, as well as their local microenvironment, play a central role in plastic deformation and key mechanical and physical properties governed by their formation and motion. Prof. Gerberich devoted his career to making seminal contributions to understanding defects, with the ultimate commemoration on his gravestone: “Science of Material Dislocations.” Evidence is also emerging of confined phases that remain anchored to crystalline defects including planar defects and dislocations, requiring the identification of the chemical, structural, and magnetic degrees of freedom at the single defect level. We highlight recent developments in dislocation characterization across a suite of electron microscopy modalities. We show how these techniques can be employed for in-situ experiments to study the nature of dislocations dynamics in several metals and alloys, including Heusler alloys hosting distinct spin exchange interactions within dissociated dislocations and FCC alloys hosting local chemical and structural ordering in the vicinity of dislocation cores. |
