Summary The presence of deformation twinning in magnesium introduces significant challenges for predicting the bulk response of the material. In this work, we present results showing the presence of tensile twins formed within pre‐existing tensile twins in samples deformed in compression at 77 K. Such double twins mirror the observation of double compression‐tension twins previously observed. It is argued that the observed double twinning occurs due to the difficulty of non‐basal slip at the low test temperature.
