Predictive Simulation of Process Windows for Powder Bed Fusion Additive Manufacturing: Influence of the Powder Bulk Density
The resulting properties of parts fabricated by powder bed fusion additive manufacturing processes are determined by their porosity, local composition, and microstructure. The objective of this work is to examine the influence of the stochastic powder bed on the process window for dense parts by means of numerical simulation. The investigations demonstrate the unique capability of simulating ma...
متن کاملOptimum conditions for adsorptive storage.
The storage of gases in porous adsorbents, such as activated carbon and carbon nanotubes, is examined here thermodynamically from a systems viewpoint, considering the entire adsorption-desorption cycle. The results provide concrete objective criteria to guide the search for the "Holy Grail" adsorbent, for which the adsorptive delivery is maximized. It is shown that, for ambient temperature stor...
متن کاملBulk graphdiyne powder applied for highly efficient lithium storage.
Here, we prepared bulk graphdiyne (GDY) powder with porous structure and explored its lithium storage properties. The assembled lithium ion batteries exhibited superior electrochemical performance, including high specific capacity, excellent rate performance and long cycle life, which should be attributed to the unique structure, high electronic conductivity and chemical stability of GDY.
متن کاملStress, strain, and bulk microstructure in a cohesive powder.
Spin-echo small-angle neutron scattering is able to characterize powders in terms of their density-density correlation function. Here we present a microstructural study on a fine cohesive powder undergoing uniaxial compression. As a function of compression, we measure the autocorrelation function of the density distribution. From these measurements we quantify the typical sizes of the heterogen...
متن کاملOptimum deposition conditions of ultrasmooth silver nanolayers
UNLABELLED Reduction of surface plasmon-polariton losses due to their scattering on metal surface roughness still remains a challenge in the fabrication of plasmonic devices for nanooptics. To achieve smooth silver films, we study the dependence of surface roughness on the evaporation temperature in a physical vapor deposition process. At the deposition temperature range 90 to 500 K, the mismat...
