| 中文摘要 | Structural change of deformation twin boundaries in gamma phase of a Ti-45Al-10Nb-2.5Mn alloy with similar to 29% deformation strain has been investigated by TEM. We found numerous bent twins propagating in the gamma matrix, which were inclined at angles of a few degrees to the (111)(M) plane in the gamma matrix. HREM observations showed that (111)(DT) plane in the twins exhibited a large misorientation angle with the (111)(M) plane, and many 1/3[111] Frank partial dislocations were observed in the incoherent twin boundaries. These 1/3[111] Frank partials, which were possible to form through dissociations of matrix dislocations at the twin boundaries, can accommodate the bending of the twins and the misorientation from the true-twin orientation relationship.
