Coercivity Improvement in Ce‐Containing (Nd,Pr)‐Fe‐B‐Based Sintered Magnets by Application of the 2‐Powder Method

open access: yesAdvanced Engineering Materials, EarlyView.
This study investigates the magnetic properties and microstructures of 2PM‐manufactured Ce‐containing (Nd,Pr)‐Fe‐B magnets. The addition of Nd and Dy significantly enhances coercivity by 25% and 81%, respectively, attributed to core‐shell structures.

Tribology of ZrC Coatings and Spherical Tips Acquired with Extraordinarily Stiff, Metal Atomic Force Microscopy Probes

open access: yesAdvanced Engineering Materials, EarlyView.
In this research, ZrC coatings are evaluated against various counterprobes at the microscale using novel super‐stiff atomic force microscopy cantilevers. The chemical composition of the coating is shown to be an important factor influencing coating hardness and Young's modulus, while surface roughness, counterprobe hardness, and surface energy are the ...

Replicating computational atmospheric science

open access: yes, 2017
Scientific claims can be verified by reproducing or replicating the experiment. Replication involves new authors writing new code following the original method. Reproduction involves new authors running the original code. Doing nothing means that scientific claims remain unverified.This talk is based on the work of Lorena Barba and was also inspired by

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.
