{11¯24} deformation twinning in commercial purity titanium at room temperature

Steven J. Lainé and Kevin M. Knowles (2015) deformation twinning in commercial purity titanium at room temperature. Philosophical Magazine, http://dx.doi.org/10.1080/14786435.2015.1051157

Table 1. Crystallography of possible deformation twinning modes in CP titanium using standard nomenclature for the twin plane K₁, shear direction η₁, second undistorted plane K₂ and direction η₂ lying in K₂ and the plane of shear [5–7]. For each deformation twinning mode a specific K₁ is selected to emphasize the crystallographic relations between K₁, η₁, K₂ and η₂. q is the complexity of the shuffles required to ensure all atoms in the twin are carried into their final correct positions [5–7]. ‘T’ and ‘C’ refer to the nomenclature of tension (T) and compression twins (C), which define whether the shape change produced by the twinning mode causes extension or contraction along the c-axis, respectively [5,6].

When the above article was first published online, there was an error in Table 1. The table should have appeared as printed below. This has now been corrected in both the print and online versions.

Table

Type	K1	η1	K2	η2	Misorientation angle/axis (for c/a = 1.588)	Shear magnitude |S|	q	Refs.
T					85.03°	0.174	4	[5,6]
T					34.96°	0.630	2	[5,6]
C^a					76.89°	0.219	6	[5,6]
C					64.40°	0.219	6	[5,6]
C					57.22°	0.099	8	[5,6]

^a is a compression twinning mode despite the assertions by Yoo [5] and Christian and Mahajan [6] that it is a tension twinning mode. See the text for details.
