Also known as 3D printing, additive manufacturing (AM) is a disruptive new manufacturing technique that is employed to create metallic parts with enhanced mechanical properties in contrast to other ...

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 ...

The study includes the manufacturing process of super-invar alloy of WAAM, the relationship between micro-structure and G/R, the mechanical properties and the CTE. The main transfer mode of liquid ...

For decades researchers have studied materials from structures to see why and how they fail. Before catastrophic failure, there are individual cracks or dislocations that form, which are signals that ...
