The titanium round wires could be prepared to the high precision flat wireswith the sizes of 0.63mm×5.03mm by nine-pass cold continuous rollingprocess.Mechanical property and metallograph analysis were used to analyze the possibilities of preparing flat wire. Results show that the grain keptequiaxed grain in the rolling processes,and a large number of dislocationand a small amount of twin existed in the microstructure of final rollingflat wire.During the whole rolling processes, when the accumulated rollingdeformation degree was at low degree, the deformation of titanium wascontrolled under the mutual control of dislocation slip and twinning. Whenthe accumulated rolling deformation degree was at high degree, the deformation of titanium was controlled by the dislocation slip.
