抄録

The surface morphology of polycrystalline titanium after tensile deformation was investigated by means of scanning probe microscope. It has been shown that the both the free surface roughness and the height different between grain boundaries and inner grain are increased with the increasing strain, and the slip steps in increase linearly with the strain ε for ε<0.3, while remain constant for ε>0.3.
