Lab co-authors Nature Communications study on slip banding in CrCoNi alloys

A UC Irvine team led by Prof. Penghui Cao, with Prof. Rimoli among the co-authors, reported in Nature Communications that two distinct types of slip bands form in the CrCoNi alloy under compression. Confined bands follow the classical Frank-Read picture of repeated dislocation emission, while extended bands grow through the deactivation of dislocation sources and the creation of new ones on neighboring planes. The work combined multiscale experiments and modeling from the microscopic to the atomic scale.
