Abstract:
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 ana
lyze 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 defor
mation of titanium was controlled by the dislocation slip.
