Incipient plasticity during nanoindentation at grain boundaries in body-centered cubic metals

The mechanical response to nanoindentation near grain boundaries has been investigated in an Fe–14%Si bicrystal with a general grain boundary and two Mo bicrystals with symmetric tilt boundaries. In particular, the indentations performed on the Fe–14%Si show that as the grain boundary is approached,...
