A Perspective on Powder Metallurgy and Additive Manufacturing of High‐Nitrogen Alloyed Stainless Steels

open access: yesAdvanced Engineering Materials, EarlyView.
This perspective article explores an innovative powder metallurgical approach to producing high‐nitrogen steels by utilizing a mixture of stainless steel and Si3N4. This mixture undergoes hot isostatic pressing followed by direct quenching. The article also examines adapting this method to laser powder bed fusion (PBF‐LB/M) to overcome nitrogen ...

Electrical safety in spinal cord stimulation: current density analysis by computer modeling [PDF]

open access: yes, 1995
The possibility of tissue damage in spinal cord stimulation was investigated in a computer modeling study. A decrease of the electrode area in monopolar stimulation resulted in an increase of the current density at the electrode surface.

Chronoamperometry at Channel Electrodes: Theory of Double Electrodes

open access: yesThe Journal of Physical Chemistry, 1994
A theoretical treatment is presented which permits the computation of transient effects at double-channel electrodes. In particular, the current response of a downstream «detector» electrode to a potential step at an upstream «generator» electrode is established, and it is shown that such experiments can provide unique information both about the ...

Deformation Behavior of La2O3‐Doped Copper during Equal Channel Angular Pressing

open access: yesAdvanced Engineering Materials, EarlyView.
By additions of strengthening elements and/or structure optimization, the mechanical properties of copper can be increased while keeping favorable electric conductivity. By combining addition of La2O3 and processing by equal channel angular pressing, substructure development is achieved, leading to increase in microhardness to more than double the ...
