Dynamic recrystallization (DRX) is almost universally observed in the microstructure of adiabatic shear bands. It is usually admitted that DRX results from the large temperatures that develop in the band along with very high local strains. This paper reports the observation of dynamically recrystallized nanograins in Ti6Al4V alloy specimens that were impact loaded to only half the failure strain at which the adiabatic shear band develops. This observation shows that DRX not only precedes…

Microstructural Aspects of Adiabatic Shear Failure in Annealed Ti6Al4V

This work reports a comprehensive examination of the microstructural evolution in Ti6Al4V subjected to high-strain-rate deformation. The sequence of microstructural rearrangements leading to

The genesis of adiabatic shear bands

Adiabatic shear banding (ASB) is a unique dynamic failure mechanism that results in an unpredicted catastrophic failure due to a concentrated shear deformation mode. It is universally considered as a

A different viewpoint on adiabatic shear localization

This short review addresses the adiabatic shear failure mechanism (adiabatic shear banding—ASB) in metals subjected to high strain-rate deformations. ASB is usually considered as an instability

Mechanical Characterization of Impact-Induced Dynamically Recrystallized Nanophase

Dynamic failure of impact-loaded structures is often caused by dynamic shear localization, that is also known as adiabatic shear banding (ASB). While ASB has long been thought to be triggered by

Adiabatic shear banding of hot-extruded tungsten heavy alloy under cryogenic temperature

The effect of cryogenic temperature on adiabatic shear banding (ASBing) of tungsten heavy alloy (WHA) processed by hot-hydrostatic extrusion was investigated. Results show that, when the initial
