Metals with a body-centered cubic (bcc) crystal structure are the basis of an important group of structural metals in engineering applications, such as ferritic steels and many refractory alloys. The ...

Characterization of dislocation motion in the alloy using discrete dislocation dynamics (DDD) simulations. Video showing the effect of lattice strain field on the dynamic evolution of dislocations ...

Topological defects play a crucial role across various fields, mediating phase transitions and macroscopic behaviors as they propagate through space. Their role as robust information carriers has also ...

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 ...
