Microstructural Aspects of Adiabatic Shear Failure in Annealed Ti6Al4V

Abstract: 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 adiabatic shear banding is presented. A detailed microstructural comparison between two types of specimens, one that failed by adiabatic shear and the other that was strained to half its failure strain, is carried out. The main observation is that for this material, the microstructure of the two types of specimens is quali… Show more

“…3 -5 is more interesting. The stress-strain curve in Fig.3 looks similar to curves of this kind shown by Rittel [13,14]. It has a smooth peak at ǫ ∼ = 0.5 where an instability sets in, and .…”

“…A strategy especially relevant to the present paper would be to use the Rycroft-Bouchbinder techniques [16] with this dislocation theory to compute fracture toughness, or to look in detail at Rittel's observations. [13,14]; but that strategy would have to be coordinated with new experimental obsrvations.…”

“…For example, there is an intriguing set of observations by Rittel and coworkers [19][20][21][22] in which they see dynamically recrystallized grains (DRX) appearing in association with, and apparently preceding, the appearance of ASB's. I would have preferred to write this paper using parameters appropriate for Rittel's ASB-forming titanium alloy -or for Marchand and Duffy's steel -instead of using "pseudo copper."…”
