They have {11 (2) over bar6} and {11 (2) over bar2} habit planes and their misorientations to the matrix are close to 56 degrees and 63 degrees about < 10 (1) over bar0 > axis, respectively. The ad hoc performed theoretical analysis and atomic simulations allow to interpret the objects as {10 (1) over bar2} and {10 (1) over bar2} double twins formed by the simultaneous action of two twinning shears with completely re-twinned volume of primary twin. The observed inclinations from the ideal misorientations for such double twins can be explained by the compliance of the strain invariant condition in the twin boundary. It seems plausible that, once the double twin is formed, its twin boundaries are hard to move by glide of twinning disconnections. If so, these twins represent obstacles for the motion of crystal dislocations increasing the hardness of the metal.
