Paper Abstract

Using electron backscatter diffraction, the microstructural features of tension-compression-tension (T-C-T) tertiary twins are studied in coarse-grained pure polycrystalline magnesium subjected to monotonic compression along the extrusion direction in ambient air. T-C-T tertiary twins are developed due to the formation of a compression-tension double twin inside a primary tension twin. All the observed T-C-T twin variants are of TiCjTj type. TiCi+1Ti+1 (or TiCi-1Ti-1) variants are observed more frequently than TiCi+2Ti+2 (or TiCi-2Ti-2) variants. The number of tertiary twin lamellae increases with the applied compressive strain.
