K-0413 多結晶チタンの引張り変形挙動の微視的観察(G03-4 静的強度)(G03 材料力学部門一般講演)

Abstract

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.
