Figure 1. The morphology of deformation twins in a MnS inclusion embedded in a stainless steel and an atomic resolution HAADF image of a twin boundary.

Figure 1

(a) Low magnified TEM image and a corresponding SAD pattern showing the presence of deformation twins in MnS inclusion. The twin plane is identified as (111) plane. (b) A high resolution HADDF image of a twin boundary viewed along Inline graphic direction. The atomic model of TB is superimposed, where the manganese ions and sulphur ions are represented by red and green spheres, respectively. The atomic configuration of the twin boundary was identified to be the mono-layer of S instead of Mn.
