Thermodynamic Pathways of Nonequilibrium Solidification in Wire‐Arc Additive Manufacturing Fe‐Based Multicomponent Alloy Structures

Advanced Engineering Materials, EarlyView.
Geometry‐driven thermal behavior in wire‐arc additive manufacturing (WAAM) influences microstructural evolution during nonequilibrium solidification of a chemically complex Fe–Cr–Nb–W–Mo–C nanocomposite system. By comparing different deposits configurations, distinct entropy–cooling rate correlations, segregation, and carbide evolution are revealed ...

Diode Circuit-based Glass Plasma-Chemical Etching Capabilities

Mechanical Engineering and Computer Science, 2017
The paper discusses technological capabilities to improve a plasma-chemical etching (PCE) rate of the silicate glasses through a chromium mask in the equipment with a planar inductor located outside, which forms a high-frequency diode system. Suggests a case when the inductor in the form of a planar spiral antenna is above the work-piece.The PCE ...
