Title: Tension-compression-tension tertiary twins in coarse-grained polycrystalline pure magnesium at room temperature

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 T iC jT j type. T iC i+1T i+1 (or T iC i–1T i–1) variants are observed more frequently than T iC i+2T i+2 (or T iC i–2T i–2) variants. Moreover, the number of tertiary twin lamellae increases with the applied compressive strain.
