A Different Perspective on the Solid Lubrication Performance of Black Phosphorous: Friend or Foe?

open access: yesAdvanced Engineering Materials, EarlyView.
Researchers investigate black phosphorous (BP) as a standalone solid lubricant coating through ball‐on‐disc linear‐reciprocating sliding experiments in dry conditions. Testing on different metals shows BP doesn't universally reduce friction and wear. However, it achieves 33% friction reduction on rougher iron surfaces and 23% wear reduction on aluminum.

Revealing the γ′ and γ″ Phase Fractions of Additively Manufactured and Differently Heat‐Treated Nickel‐Base Superalloy IN718 by Atom Probe Tomography and Their Impact on Mechanical Properties

open access: yesAdvanced Engineering Materials, EarlyView.
Additive manufacturing is a promising route for the production of Ni‐base superalloys for turbine applications, such as Inconel 718. Nonetheless, it induces various changes in the microstructure and performance of these materials. One such change is the incidence of the δ‐Ni3Nb phase, whose impact on microstructure, aging precipitate fractions, and ...

Development of a Novel Processing Route for Dispersoid/Precipitation‐Strengthened High Conductive Copper Alloys by Using Metalized Nanoceramics in Additive Manufacturing

open access: yesAdvanced Engineering Materials, EarlyView.
This study explores a process chain to produce dispersoid‐strengthened CuCr1Zr for applications requiring high strength and conductivity. Using gas‐atomized powder and copper‐plated alumina nanoparticles, additive manufacturing is performed via powder bed based additive manufacturing with green and red lasers, followed by heat treatment.

Material Challenges and Alloy Selection for Particle/s‐CO2 Heat Exchangers in Concentrated Solar Power Systems

open access: yesAdvanced Engineering Materials, EarlyView.
Combining supercritical CO2 (s‐CO2) cycles with particle‐based heat transfer media holds great potential in concentrated solar power plants but poses enormous material challenges. The particle/s‐CO2 heat exchanger must withstand extreme conditions, including high temperatures, pressures, CO2 corrosion, and erosion.

Nonlinearity and Domain Switching in a 3D‐Printed Architected Ferroelectric

open access: yesAdvanced Engineering Materials, EarlyView.
By combining functional properties measurement with in situ 2D X‐ray microdiffraction experiments, it is shown that nonlinear polarization and strain responses of a 3D‐printed architected ferroelectric are driven by localized progression of domain switching, which depends on nonuniform electric‐field distribution as well as evolving stress fields.

StahlDigital: Ontology‐Based Workflows for the Steel Industry

open access: yesAdvanced Engineering Materials, EarlyView.
The strength of the steel industry is based on the mastery of microstructure–property relationships. Digital workflows contribute to this aim by making the complexity of workflows reproducible and their execution user independent. The tools and workflows developed in the project StahlDigital as part of the German MaterialDigital initiative are ...
