Fatigue Performance of Additively Manufactured Ti‐6Al‐4V: Impact of Different Kinds of Porosities, Surface, and Heat Treatments in Laser Powder Bed Fusion Productivity Parameters

open access: yesAdvanced Engineering Materials, EarlyView.
Ti‐6Al‐4V samples produced by laser‐powder bed fusion are tested for static and dynamic mechanical properties to systematically evaluate the effects of surface roughness and internal porosity when using productivity parameters. The most detrimental impact to fatigue is caused by surface roughness, lack of fusion and keyhole porosity in descending order.

Effect of Copper Content on the Microstructure and Mechanical Properties of As‐Cast Refractory MoNbTi Multiprincipal Element Alloys

open access: yesAdvanced Engineering Materials, EarlyView.
Copper addition profoundly impacts MoNbTi multiprincipal element alloys. This study reveals copper's dual role, promoting microstructural refinement and strengthening intermetallics at optimal concentrations. An ideal copper content significantly boosts hardness and compressive strength, achieving superior mechanical performance.

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

Toward Maximum Utilization of Heavy Rare Earths in Sintered Nd–Fe–B Magnets by Grain Boundary Diffusion Source and Application Area Optimization

open access: yesAdvanced Engineering Materials, EarlyView.
In this work, the grain boundary diffusion process is optimized to maximize heavy rare earth utilization by strategic magnetic hardening of areas in the magnet such as corners or edges that are highly susceptible to demagnetization, as demonstrated by finite element magnetostatics simulation on an internal permanent magnet, synchronous traction motor ...

NSF atmospheric science review

open access: yesEos, Transactions American Geophysical Union, 1984
The National Science Foundation's (NSF) Division of Atmospheric Sciences (ATM) is doing extremely well, according to a recently completed review of two of its grant programs by an outside advisory committee. As a major part of NSF's activities in the physical sciences, ATM is responsible for providing more than $89.3 million annually in support of ...
