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