Abstract

The A/B twin boundary (type II) in 18R martensite in a Cu-Zn-Al alloy was observed by high resolution electron microscopy. The two-dimensional lattice image suggests that the irrational interface is not a sharp ledge and step one, but gradually and randomly curved with a slight strain contrast. However, in response to applied stress, with invariant plane strain conditions, the boundary develops into a stepped structure.
