文摘	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 ℃ and (α+β)-rolled at 980 ℃, 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 1 0}[11 2 0] slipping, while the B-type texture in CDR plate was relevant with {0001}[11 2 0] 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.
