Study on the texture of TA15 titanium alloy hot-rolling plate

The annealing texture of the TA15 titanium plate hot-rolling by different rolling process has been studied. Result show that the main texture elements are (1̄21̄0)[101̄0] and (1̄21̄1)[101̄0]. The (1̄21̄0) and [101̄0] planes are parallel with the surface of the plate in the rolling-direction, vertical to the (0001) plane. The [101̄0] direction is parallel with the transvers-direction, vertical to c-axis. In the transvers-direction, the [0001] direction is parallel with the transvers-direction and c-axis. The density of pole figure in different direction or layer of the plate leads to the various tensile strength in different sampling position.
