Testing Military-Grade Adhesive in Extreme Loading Conditions
Military performance requirements for adhesives have been traditionally derived to fulfill niche defense needs in harsh operational environments with little consideration for dual-use commercial potential. The drawback ... -
Calculated Collision Welding Process Windows in Acoustic, Elastic, and Shock Approximations
Collision welding is a solid-state joining process which uses shock pressures developed during impact to metallurgically bond flyer and target plates. Various analytical expressions have been developed to describe the ... -
Development of a Diffusion Mobility Database for Co-based Superalloys
To facilitate the development of high-temperature Co-based gamma-gamma prime superalloys, a Co-Ni based diffusion mobility database is developed for the eight component FCC (Face Centered Cubic) system of Co-Al-W-Ni-Cr-Ti-Ta-Re. ... -
Ws2-WTe2
(2016)First principles phase diagram calculations, that included van der Waals interactions, were performed for the bulk transition metal dichalcogenide system (1-X)WS_2 - (X)WTe_2. To obtain a converged phase diagram, a ... -
MoS2-MoTe2
A first principles phase diagram calculation, that included van der Waals interactions, was performed for the 3D bulk system (1−𝑋)·𝑀𝑜𝑆2−(𝑋)·𝑀𝑜𝑇𝑒2. Surprisingly, the predicted phase diagram has at least two ordered ... -
Use of spherical nanoindentation protocols to study the anisotropic mechanical response of alpha-beta single colonies in Ti-6Al-4V alloy
The recently developed spherical nanoindentation stress-strain protocols were employed in this study to investigate systematically the anisotropic elastic and yield response of the α-β single colonies in a Ti-6Al-4V alloy. ... -
Cubic crystal compounds - Jarvis DFT
This is the dataset of materials obtained from the Jarvis-DFT dataset and used for the study "Machine learning approaches for feature engineering of the crystal structure: Application to the prediction of the formation ... -
HMX microstructural data of beta, delta, and beta-reversion
X-ray computed tomography of large HMX crystals, and scanning electron microscopy of focused ion beam milled/polished small HMX crystals of varying solid phases. -
Spherical nanoindentation stress-strain curves of primary-α grains in Ti5-2.5, Ti811, Ti64, Ti6242 and Ti6246 alloys
Recently established spherical indentation stress-strain protocols have demonstrated the feasibility of measuring reliably the mechanical responses at different material structure length scales in a broad range of structural ... -
Synthetic X-ray Microtomographic Image Data of Fiber-reinforced Composites
(2019)A new algorithm was developed to segment three-dimensional fibers in multi-directional fiber-reinforced composites (FRCs) imaged using X-ray microtomography (µCT). Validation of the algorithm was performed using synthetic ... -
Mechanical Testing Data Upload June 2019
File contains characterization data related to carbon fiber composite coupons and constituents. -
Thermodynamic analysis of the topologically close packed σ phase in the Co-Cr system
(2019-11)Density functional theory (DFT) calculations show that it is essential to consider the magnetic contribution to the total energy for the end-members of the σ phase. A more straightforward method to use the DFT results in ... -
Thermodynamic assessment of the Co-Ta system
(2018-12)The Co-Ta system has been reviewed and the thermodynamic description was re-assessed in the present work. DFT (density functional theory) calculations considering spin polarization were performed to obtain the energies for ... -
Materials Informatics Approach to Material Extrusion Additive Manufacturing
Processing-structure-property relationships in material extrusion additive manufacturing are complex, non-linear, and poorly understood. In this work, we designed an informatics workflow for the collection of high pedigree ... -
Impact of solutes on the lattice parameters and elastic stiffness coefficients of hcp Fe from first-principles calculations
(2018-12-16)The hexagonal close-packed (hcp) $\epsilon$-martensite phase in steels nucleates from the austenite parent phase during plastic straining and can be stabilized by solute additions. We compute the lattice parameters and ... -
Geometries of edge and mixed dislocations in bcc Fe from first principles calculations
We use density functional theory (DFT) to compute the core structures of a_0[100](010) edge, a_0[100](011) edge, a_0/2[-1-11](1-10) edge, and a_0/2[111](1-10) 71 degree mixed dislocations in body-centered cubic (bcc) Fe. ... -
