Many nanotwins were formed in this triangular region. HREM observations showed that nanotwinning dislocations were nucleated at noncoherent twin boundaries with the local stress concentration, and the nucleation is related to the dislocation dissociations at the boundary ledges. The proceeding of these nanotwins is the homogenous shears of 1/6 [11〓] twinning dislocations, which is that the trailing 1/6 [112] twinning dislocations repel the leading twinning dislocations to proceed in the (111) planes. Therefore, twinning dislocations at the twin tip appear to be on one side of twin, forming a noncoherent twin boundary with a semilenticular shape.

在此三角区域内发现许多纳米孪晶的存在，通过高分辨电镜手段观察到纳米孪晶中的孪生位错是在具有原位应力集中的非共格入射孪晶界上形核的，纳米孪晶的形核与界面的台阶位错及其位错分解反应有关，纳米孪晶的行进是1/6[11〓]孪生位错均匀切变机制，即每一个（111）孪生面上对应一个孪生位错，其中拖尾的1/6[11〓]孪生位错将会推动领先的孪生位错行进，于是在形变孪晶头部位置的孪生位错排列常常出现在形变孪晶的一侧界面，形成一个半透镜状的非共格孪晶界。
