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 ...

In a landmark advancement for structural materials engineering, researchers have developed a novel heterostructured titanium matrix composite that demonstrates exceptional mechanical performance from ...

Research has shown that face-centered cubic (fcc) composites with high-density and nanoscale deformation twins can greatly improve the balance of ductility and strength. Still, the microscopic ...

For nearly a century, scientists have understood how crystalline materials—such as metals and semiconductors—bend without breaking. Their secret lies in tiny, line-like defects called dislocations, ...

An international team of researchers, led by University of Toronto Engineering Professor Yu Zou, is using electric fields to control the motion of material defects. This work has important ...
