Processing Parameter DOE for 316L Using Directed Energy Deposition

Journal of Manufacturing and Materials Processing, 2018
The ability to produce consistent material properties across a single or series of platforms, particularly over time, is the major objective in metal additive manufacturing (MAM) research. If this can be achieved, it will result in widespread adoption of

Deposition characterization of high-manganese (13Mn) steel built via directed energy deposition and its wear behavior

Journal of Materials Research and Technology, 2023
High-manganese steel (HMS) has high work-hardening and impact toughness as well as excellent wear resistance. In this study, directed energy deposition (DED) was employed to deposit HMS onto the surface of Inconel 718. The deposition characteristics were

Surface-directed spinodal decomposition in the pseudobinary alloy (HfO_2)_x(SiO_2)_{1-x}

, 2010
Hf silicate films (HfO_2)_{0.25}(SiO_2)_{0.75} with thicknesses in the range 4-20 nm were grown on silicon substrate by atomic layer deposition at 350 deg.C.The Hf distributions in as-grown and 800 deg.C annealed films were investigated by high ...

Microscale adhesion patterns for the precise localization of amoeba [PDF]

, 2008
In order to get a better understanding of amoeba-substrate interactions in the processes of cellular adhesion and directional movement, we engineered glass surfaces with defined local adhesion characteristics at a micrometric scale. Amoeba (Dictyostelium

Growth of (110) Diamond using pure Dicarbon [PDF]

, 2000
We use a density-functional based tight-binding method to study diamond growth steps by depositing dicarbon species onto a hydrogen-free diamond (110) surface.

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

FEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Deposition of diamondlike carbon films [PDF]

, 1984
A diamondlike carbon film is deposited in the surface of a substrate by exposing the surface to an argon ion beam containing a hydrocarbon. The current density in the ion beam is low during initial deposition of the film.
