In-situ observation of dislocation dynamics near heterostructured interfaces

In-situ observation of dislocation dynamics near heterostructured interfaces

There has been a long-standing controversy on how dislocations interact with interfaces. Here we report in-situ observations that in a Cu–brass heterostructured TEM film Frank–Read sources are the primary dislocation sources. They were dynamically formed and deactivated throughout the deformation in...
