Dynamic mechanisms of strengthening and softening of coherent twin boundary via dislocation pile-up and cross-slip
Z Li, J Zhang, Y Zhai, J Zhang, X Wang… - Materials Research …, 2022 - Taylor & Francis
Although cross-slip strongly affects the deformation of polycrystalline materials, the
phenomenon is rarely studied in twinned face centered cubic (FCC) metals. Here we …
