- Abstract
Polycrystalline magnesium of 99.8 wt.% purity
was subjected to high-pressure torsion (HPT) at room
temperature. A special technique was developed in order to
enable HPT of Mg up to very high shear strains of 115 and
hydrostatic pressures of 4 GPa. The texture development
during HPT was investigated by systematic X-ray texture
measurements. It can be described by a stationary oblique
B fibre characteristic of hexagonal metals subjected to
simple shear. From the measured shear strain and pressure
dependences of the B fibre and from microstructure
investigations by TEM, it is concluded that also mechanisms
of both dynamic and of static recrystallization
contribute to the texture evolution.
