Multiple Twinning

The misorientations induced by cold-rolling in commercially pure titanium by twinning and multiple twinning were investigated by electron backscatter diffraction. Three main types of twins occur: compressive twins (64.6° 〈1\overline 100〉) which are predominant, followed by tensile twins of type 1 (84.8° [11\overline 20]) and a few of type 2 (35.1° 〈1\overline 100〉). The main multiple twinning configurations are (i) several variants of a given type of twin inside a given grain and (ii) second-generation tensile twins inside primary compressive twins. All possible misorientations resulting from the combination of two out of the three main twinning systems have been calculated and compared with the experimentally observed twin configurations. This facilitated interpretation of the peak found at 41° 〈5\overline 1\overline 43〉 in the misorientation distribution as the result of double twinning (tensile twins inside primary compressive twins).
