Role of grain boundary sliding in the anisotropy of magnesium alloys
journal contribution
posted on 2009-08-01, 00:00 authored by Matthew BarnettMatthew Barnett, Alireza Ghaderi, Ilchat Sabirov, B HutchinsonThe plastic anisotropy of magnesium alloy sheet drops rapidly with test temperature. It has previously been suggested that this may be due to an increase in the activity of (c+a) dislocations. The present note points out that the phenomenon may result, instead, from the action of grain boundary sliding. This can explain the strong effect of grain size on anisotropy. Furthermore, it points to a new avenue for alloy development.
