Atomic-scale study of the {112¯1} twinning and {112¯2}-{112¯1} double twinning mechanisms in pure titanium

•The {112¯1} twin embryo is composed of a group of pyramidal stacking faults (PSFs) with 6d{112¯1} or 8d{112¯1} caused by successive slip of partial dislocations with the Burgers vector of 136M.•The growth of {112¯1} twin can be carried out by the slip of twinning dislocations (TDs) b⇀1 = 16(4γ2+1)...
