Effect of solutes on the lattice parameters and elastic stiffness coefficients of body-centered tetragonal Fe
(2018-03-03)We compute changes in the lattice parameters and elastic stiffness coefficients Cij of body-centered tetragonal (bct) Fe due to Al, B, C, Cu, Mn, Si, and N solutes. Solute strain misfit tensors determine changes in the ... -
Thermodynamic re-assessment of the Al-Co-W system
The Al-Co-W system and its binary sub-systems Al-Co, Al-W and Co-W were critically reviewed. The thermodynamic description of the Al-Co-W system including all three binaries was developed considering thermodynamic and ... -
Evaluating error with atomistic simulations: the effect of potential and calculation methodology on the modeling of lattice and elastic constants
Atomistic simulations using classical interatomic potentials are powerful investigative tools linking atomic structures to dynamic properties and behaviors. It is well known that different interatomic potentials produce ... -
A computational framework for material design
(2017-08-18)A computational framework is proposed that enables the integration of experimental and computational data, a variety of user-selected models, and a computer algorithm to direct a design optimization. To demonstrate this ... -
Synchrotron Diffraction and Composition Data Sets of Co-Fe-Zr Metallic Glasses
(2017-07-12)The dataset summarizes a series of high-throughput studies on the Co-Fe-Zr metallic glass system with a total of 1323 unique alloys having been investigated. The primary goal of the work was to identify unsupervised ... -
Interdiffusion in the Ni-Re System: Evaluation of Uncertainties
(2017-06-22)Diffusion couple experiments between Ni and Re at 1200 and 1350 °C were performed. These experiments established the limits of the two-phase FCC + HCP region. No intermediate phase was observed at these temperatures. ... -
Thermodynamic Description of the Ti-Al-O System Based on Experimental Data
(2017-06-08)Phase equilibria of the TiO2-Al2O3 system were investigated experimentally using XRD, SEM/EDX and DTA methods. Temperature stability limits of the aluminum titanate (Al2TiO5) were detected. The thermodynamic parameters of ... -
NIST Ni-based diffusion mobility database
The NIST Ni-based diffusion mobility database was originally constructed for the fcc phase of the Ni–Al–Co–Cr–Hf–Mo–Re–Ta–Ti–W system. Diffusion data in various constituent binary systems were assessed to establish a ... -
A Study in Phase Equilibria in the Cr-Mo-Ni System
A thermodynamic evaluation of the Cr-Mo-Ni system has been performed using a computerized optimization procedure . Parameters describing the Gibbs energy of the various phases have been calculated. The intermetallic phases ... -
Ultrahigh Carbon Steel Micrographs
We present a new microstructure informatics dataset consisting of ultrahigh carbon steel (UHCS) micrographs taken over a range of length scales under systematically varied heat treatments. Using the UHCS dataset as a case ... -
Single-Lap-Joint Screening of Hysol EA 9309NA Epoxy Adhesive
A commercial 2-part epoxy was evaluated per ARL-ADHES-QA-001.00 rev 1.0, which consists of single-lap-joint testing at room temperature and subsequent hot/wet and elevated temperature conditioning. This testing protocol ... -
Initial Screening of Environmentally Sustainable Surface Pretreatments for Adhesive Bonding Applications
