Effects of Processing on Microstructure and Mechanical Properties of Ti-6Al-4V Fabricated using Electron Beam Melting (EBM), Part 1: Distance from Build Plate and Part Size

June 20, 2013
Author(s)
Nikolas W. Hrabe, Timothy P. Quinn, Ryan Kircher
… intra-build processing parameters: distance from the build plate and part size. Microstructure evaluation (qualitative … not found to vary as a function of distance from the build plate, which was hypothesized to be influenced by the build plate preheating associated with the EBM process. Part size …

Evidence of Antiferromagnetism in Ultrathin Metallic (111)-Oriented LaNiO3 Films

December 11, 2024
Author(s)
Margaret Kane, Purnima P. Balakrishnan, Okan Koksal, Megan Holtz, Andreas Suter, Michael R. Fitzsimmons, Chao-Yao Yang, Christoph Klewe, Paige Quarterman, Timothy R. Charlton, Andrew Herzing, Zaher Salman, Thomas Prokscha, Rossitza Pentcheva, Alexander Grutter, Yuri Suzuki
Antiferromagnets with exotic spin textures promise low-power spintronic devices with extremely high operating frequencies and resistance to external perturbations. In particular, the combination of highly tunable correlated electron physics, as in complex

Approximate theoretical model for the five electronic states (? = 5/2, 3/2, 3/2, 1/2, 1/2) arising from the ground 3d9 configuration in nickel halide molecules and for the rotational levels of the two ? = 1/2 states in this manifold

The NIST Watt Balance: Recent Results and Future Plans

March 1, 1999
Author(s)
David B. Newell, Richard L. Steiner, Edwin R. Williams
The last remaining SI base unit defined by an artifact is the kilogram. The NIST watt balance has been designed to measure the ratio of mechanical to electrical power, linking the artifact kilogram, the meter, and the second to the practical realizations
