Effect of magnetic field on texture evolution in titanium

Abstract The effect of a high magnetic field on texture development in titanium is addressed. Cold rolled (82%) titanium shows a typical rolling texture with two components in the {0 0 0 2} pole figure, which remains after recrystallization and subsequent grain growth. The annealing of titanium sheet samples in the hexagonal phase field (750 °C) in a magnetic field of 19.4 T with the sheet normal parallel or perpendicular to the field direction does not change the final texture. In contrast, the same thermo-magnetic treatment results in a distinct difference between usually symmetrical texture peaks when the sample is tilted by +30° or −30° to the magnetic field direction around the rolling direction leading to a configuration where the c (〈0 0 0 1〉) axis of grains corresponding to one texture component is aligned normal to the magnetic field direction. This observation is attributed to grain growth affected by an additional driving force arising in a magnetic field by the anisotropy of the magnetic susceptibility of titanium.
