摘要：

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 omega plates with a single variant are formed. It is considered that such dislocation loops are expelled from the beta twin/omega interface into the beta matrix during the shrinkage of twins by unloading. Secondary {332}[113] twinning occurs in the primary twins by further deformation.
