Diffusion in the Ti-Al-V system is studied and a CALculation of Phase Diagrams (CALPHAD) diffusion mobility description developed. couple experiments are performed to obtain paths hcp phase at 923 K, 1023 K 1123 K. The coefficient V hcp-Ti found decrease with increasing Al alloying. A forward-simulation analysis used evaluate impurity for Ti-V Ti-Al systems which as input modeling. composition dependency ternary accounted CALPHAD obtained by directly optimizing parameters function...
Abstract Additive manufacturing (AM) technologies offer unprecedented design flexibility but are limited by a lack of understanding the material microstructure formed under their extreme and transient processing conditions its subsequent transformation during post-build processing. As part 2022 AM Bench Challenge, sponsored National Institute Standards Technology, this study focuses on phase composition evolution nickel alloy 718, nickel-based superalloy, to provide benchmark data essential...
Optimizing the cooperativity between two distinct particles is an important feature of quantum information processing. Of particular interest coupling spin and phonon, which allows for integrated long-range communication gates operating at gigahertz frequency. Using local light scattering, we show that, in magnetic planar geometries, this attribute can be tuned by adjusting orientation strength external field. The enhanced about a factor 2 out-of-plane magnetized geometry where Kittel mode...
Abstract The Additive Manufacturing Benchmark Test Series (AM Bench) is a broad effort to produce rigorous measurement datasets for validating AM computer simulations across the range of processing, structure, and properties, many additive manufacturing (AM) build methods material classes. Here, microstructures nickel alloy 718 Bench 2022 test artifacts produced using laser-based powder bed fusion (PBF-LB), in both as-built fully heat-treated conditions, are examined. Cross sections...
High-throughput experiments that use combinatorial samples with rapid measurements can be used to provide process-structure-property information at reduced time, cost, and effort. Developing these tools methods is essential in additive manufacturing where new required on a frequent basis as advances are made feedstock materials, machines, post-processing. Here we demonstrate the design of produced commercial laser powder bed fusion system study 60 distinct process conditions nickel...
The relationships between the force measured during wetting balance tests and observed changes of contact angle meniscus shape are studied. Experiments using silicone oil at 25, 50, 100°C on glass plates as well Pb-Sn eutectic solder Au-coated reported. Discrepancies height those expected for a static detailed. Equilibrium shapes computed wide elastica solution narrow public-domain software package, “Surface Evolver.” For room temperature experiments with oil, discrepancy disappears when...
