| Abstract: | The multi-pass cold-rolled tests of TC16 titanium alloy sheets were produced.The effect of deformation on microstructures and mechanical properties of cold-rolled sheets were studied by optical microscope,scanning electron microscope and X-ray diffraction.The results show that the cold rolling ofα+βtwo-phase TC16 titanium alloy sheets is feasible,and the limit cold deformation can reach 79%without any cracks on the surface.After large-scale cold rolling deformation,the TC16 titanium alloy microstructure becomes a uniformly distributed fibrous structure,and they are few incompletely deformedαgrains,accompanied by strain-inducedα″martensitic phase.Meanwhile,the improvement of tensile strength and microhardness,and obvious cold deformation strengthening is obtained. |
