Additive Manufacturing of Highly Alloyed Aluminum–Lithium

open access: yesAdvanced Engineering Materials, EarlyView.
Al–Li alloys, promising for future lightweight constructions due to their low density and high stiffness, are limited to 9 at% lithium in commercial forms because of segregation issues. To overcome this traditional limitation, powder bed fusion with an ultrashort pulse laser is used.

Microstructural Feature and Magnetocaloric Effect of Mn50Ni40.5In9.5 Melt-Spun Ribbons

open access: yesCrystals, 2017
The microstructure and magnetocaloric properties of the melt-spun and annealed Mn50Ni40.5In9.5 ribbons were studied. It is shown that the post-annealing results in a considerable increase of the grain size for the initial austenite, where the columnar ...

Imprints of expansion onto the local anisotropy of solar wind turbulence

open access: yes, 2015
We study the anisotropy of II-order structure functions defined in a frame attached to the local mean field in three-dimensional (3D) direct numerical simulations of magnetohydrodynamic turbulence, including or not the solar wind expansion.

Influence of a Standard Heat Treatment on the Microstructure and Properties of Inconel X‐750 Produced by Laser Powder Bed Fusion

open access: yesAdvanced Engineering Materials, EarlyView.
Ni‐base superalloys produced using additive manufacturing (AM) have a different response to heat treatments when compared to their conventional counterparts. Due to such unpredictability, various alloys with industrial interest are currently overlooked in most prior AM research.

The loss of anisotropy in MgB2 with Sc substitution and its relationship with the critical temperature

open access: yes, 2005
The electrical conductivity anisotropy of the sigma-bands is calculated for the (Mg,Sc)B2 system using a virtual crystal model. Our results reveal that anisotropy drops with relatively little scandium content (< 30%); this behaviour coincides with the ...

CMB anisotropy experiments [PDF]

open access: yesPhysics Reports, 2000
Abstract Anisotropies in the cosmic microwave background (CMB) encode information about the evolution and development of the universe. Quality observations of CMB anisotropies can provide a very strong test of cosmological models and provide high precision determination of major cosmological parameters.

Mechanical and Microstructural Effects of ZrO2 Nanoparticles in Fe20Cr Oxide Dispersion‐Strengthened Alloys Processed by Laser Powder Bed Fusion

open access: yesAdvanced Engineering Materials, EarlyView.
The influence of oxide nanoparticle synthesis route and concentration on microstructure and high‐temperature performance of additively manufactured oxide dispersion‐strengthened steels is investigated. Comparing laser‐generated and chemically synthesized ZrO2 nanoparticles, the study reveals how dispersion quality, crystal structure and particle size ...

Antibacterial metals and alloys for potential biomedical implants

open access: yesBioactive Materials, 2021
Metals and alloys, including stainless steel, titanium and its alloys, cobalt alloys, and other metals and alloys have been widely used clinically as implant materials, but implant-related infection or inflammation is still one of the main causes of ...

Non-Parametric Approximations for Anisotropy Estimation in Two-dimensional Differentiable Gaussian Random Fields

open access: yes, 2016
Spatially referenced data often have autocovariance functions with elliptical isolevel contours, a property known as geometric anisotropy. The anisotropy parameters include the tilt of the ellipse (orientation angle) with respect to a reference axis and ...
