“…In the deformation localisation region in a specimen, in addition to grain fracturing, rotating and elongating,20 there is sometimes a bright white line on the etched surface in the middle of the shear band,18,19 the so called white shear band. Figure 3 is an optical micrograph showing a white shear band in the BT16 titanium alloy after dynamic deformation at 300 mm s −1 to 66·7%.…”

The relationship between microstructure and deformation and damage behaviour during dynamic compression in Ti-3Al-5Mo-5V alloy has been studied using several experimental techniques, including optical microscopy, scanning electron microscopy and microhardness measurements. It was found that the deformation behaviour during dynamic compression was closely related to deformation parameters. After dynamic deformation, the deformation shear band that formed in the titanium alloy had microhardness similar to that of the matrix. However, the microhardness of the white shear band was much higher than the matrix microhardness. The effects of deformation parameters, including deformation rate and deformation degree, on deformation localisation were investigated. Based on the results from the present work, the microstructure and deformation processing parameters can be optimised. In addition, treatment methods after dynamic compression were explored to restore alloy properties. Using post-deformation heat treatment, the microstructure and property inhomogeneity caused by shear bands could be largely removed.

“…The main reason is that the transition zones transform into part of shear band. Zhang et al [28] proposed that the width of shear band was considered to be a symbol of localized deformation degree. Thus, the deformation behavior of Ti-6Al-4V alloy can be evaluated by the analysis of ASB width.…”

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.
