Adiabatic shear band (ASB) was narrow region where softening occurred and concentrated plastic deformation took place. In present study, the effects of height reduction and deformation temperature on ASB were investigated by means of optical microscopy (OM) and scanning electron microscopy (SEM). And the deformation mechanisms within the shear band were discussed thoroughly with the help of transmission electron microscopy (TEM). There is a critical strain for the formation of ASB during warm compression of Ti–6Al–4V alloy. The width of ASB increases with height reduction increasing. Elongated alpha grains within shear band grow up with deformation temperature increasing. Some ultrafine grains that confirm the occurrence of dynamic recrystallization are observed within shear band during warm compression of Ti–6Al–4V alloy.
There is a critical strain for the formation of adiabatic shear band during warm compression of Ti–6Al–4V alloy. Some ultrafine grains within shear band are observed during warm compression of Ti–6Al–4V alloy; it confirms the occurrence of dynamic recrystallization of α phase.
