This paper presents an extensive study of the conditions of appearance of mechanical twinning and its role in the texture development during uniaxial tension, biaxial expansion and rolling of Ti and Zr alloys.

With the help of literature, the analyses are extended to alloys of Mg, Zn and Be.

Finally, the influence of twinning on the shape of the forming limit diagrams and on formability is discussed for hexagonal metals.
