The defect-formation processes in coarse-fine-grained As4S4/ZnS nanocomposites are shown to occur in homochemical environment of more compact fine-grained ZnS nanoparticles inserted in looser coarse-grained As4S4 environment.
While it is well-known that supersaturated cubic-structured Ti1−xAlxN can be prepared by physical vapor deposition, the impact of point defects on formation process and cubic to wurtzite transition is largely unexplored.
The load requirement and possible defect formation during the process were predicted by employing a rigid-viscoplastic finite element analysis.
In order to study the effects of bias voltage (Ub) on the defect formation during HIPIMS process, four sets of CrN/NbN coatings were deposited at Ub = −40 V, −65 V, −100 V and −150 V.
We use dispersion behavior of the intensity ratio, band position, and linewidth of the D, G, D′, and G′ bands to probe the defect formation and oxidation process in MWCNTs.
Therefore, as an integrated parameter, energy density represents the combined effect of the major process parameters on defect formation in an SLM process.
Furthermore, we investigate the influence of different kinds of surface defects on the formation process of supported Au clusters and the role of these effects in the production and design of highly dispersed ultrafine Au particles.
This paper reviews defect formation mechanisms in SLM processes, discusses the effect of process parameters on defect formation, and proposes a strategy for defect suppression and control.
Based on the principle that laser selectively melts the powders, the major factors which are related to defect formation in an SLM process are laser energy input, powder material, and scan strategy.
A kinetic model with two competing processes (defect formation and defect scavenging) was adopted to interpret the observed nonlinear time-dependent intensity ratio trends.
