Abstract

Abstract Micro-cantilevers with an equilateral triangular cross-section and an apex at the bottom were machined across grain boundaries in a Ti–6Al alloy sample using a focused ion beam (FIB). A nano-indenter was used to deform the micro-cantilevers. An prism slip system was selectively activated in the upper grain by controlling the crystal orientation along the micro-cantilever. Specimens for transmission electron microscopy (TEM) were prepared from the deformed micro-cantilevers using dual-beam FIB. Bright field scanning transmission electron microscopy was used to investigate the process of slip propagation through the grain boundary.
