Abstract

Abstract

In order to study the evolution law and mechanism of titanium adiabatic localization shear band under cold rolling conditions, conclusions were drawn by exploring and analyzing the cold rolling process. Firstly, the morphology of the shear band was analyzed, followed by the microhardness, and finally the evolution of local shear strain and local temperature increment. The results show that after deformation from 50% to 83% in cold rolling, the edge of the cold rolled titanium plate first forms a deformation zone, in which a local shear band with an angle of 40° to the rolling direction is formed, and the width of the shear band is about 25 μm. In the center of the shear band, there are ultrafine nanocrystals with the size of 20-160 nm and the average size of 70 nm. Through the microhardness test reslut, it can be concluded that the hardness in the center of the shear band is significantly higher than that around the matrix. The calculated shear strain and maximum temperature increment in the shear zone are much higher than that of the whole deformed sample localized shear bands originate from the geometrical instability of the microstructure rather than thermal disturbance.
