In a Ti-15V-3Cr-3Sn-3Al alloy, the internal structure of {332}〈113〉 deformation twins formed by weak rolling at 77 K was studied by means of transmission electron microscopy. {332}〈113〉 deformation twins accompany very characteristic dislocation loops attached to the twin/matrix interface in the matrix. Inside the twin, a parallel array of stress-induced ω plates with a single variant are formed. It is considered that such dislocation loops are expelled from the β twin/ω interface into the β matrix during the shrinkage of twins by unloading. Secondary {332}〈113〉 twinning occurs in the primary twins by further deformation.
