Journal ArticleDOI
Influence of anisotropy (crystallographic and microstructural) on spallation in Zr, Ta, HY-100 steel, and 1080 eutectoid steel
TL;DR: In this article, the authors quantify the influence of textural and microstructural anisotropy on spallation in high-purity polycrystalline Ta and Zr materials.
Journal ArticleDOI
Investigation of the shear response and geometrically necessary dislocation densities in shear localization in high-purity titanium
Chaoyi Zhu,Veronica Livescu,Tyler Harrington,Olivia F. Dippo,George T. Gray,Kenneth S. Vecchio +5 more
TL;DR: In this article, the influence of microstructural anisotropy on shear response of high-purity titanium was studied using the compact forced-simple-shear specimen (CFSS) loaded under quasi-static loading conditions.
Journal ArticleDOI
Deformation of polycrystalline Ni3Al at high strain rates and elevated temperatures
H.W. Sizek,George T. Gray +1 more
TL;DR: In this article, a wide range of strain rates (0.001 −8000 s−1) and temperatures (77 −1273 K) were used to study the variability in the yield and flow stress/temperature of polycrystalline Ni3Al with 0.095 at.
Journal ArticleDOI
Effect of peak stress and tensile strain-rate on spall in tantalum
TL;DR: In this paper, a series of flyer-plate impact tests on high purity tantalum were conducted to evaluate the spall strength and peak stress in the free-surface free-surface of the samples.
Journal ArticleDOI
The influence of oxygen on the structure, fracture, and fatigue crack propagation behavior of Ti-8.6 Wt Pct Al
TL;DR: In this article, the effect of interstitial oxygen content on the structure, fracture, and fatigue crack propagation behavior of Ti-8.6A1 in vacuum was found to vary with the R ratio, while at R = 0.7, increasing oxygen from 500 to 1000 or 2000 ppm increased FCP rates.
