Abstract:

Rolling texture and its effect on tensile properties of Ti60 alloy plates were investigated in the present study. The plates were β-rolled at 1070 °C and (α + β)-rolled at 980 °C, using uni-directionally rolling (UDR) and cross-directionally rolling (CDR) processes, respectively. β-rolled plates exhibited weak textures, which were attributed to the dispersive orientations of secondary α during the β → α phase transformation. Strong deformation textures formed in (α + β)-rolled plates as a result of slipping mechanisms: the strong T-type texture in UDR plate was related to {10 1ˉ0}[11 2ˉ0] slipping, while the B-type texture in CDR plate was relevant with {0001}[11 2ˉ0] slip. Strong T-type textures led to anisotropic tensile properties. B-type textures would decrease such an anisotropy. The (α + β)-CDR process was found to be a candidate process for reducing anisotropy of Ti60 alloy plates.
