Phase Transitions: Sublimation and Deposition
0 Views •
2020
Some solids can transition directly into the gaseous state, bypassing the liquid state, via a process known as sublimation. At room temperature and standard pressure, a piece of dry ice (solid CO2) sublimes, appearing to gradually disappear without ever forming any liquid. Snow and ice sublimate at temperatures below the melting point of water, a slow process that may be accelerated by winds and the reduced atmospheric pressures at high altitudes. When solid iodine is warmed, the solid sublimes...

We present the synthesis of the organic-based ferrimagnet vanadium tetracyanoethylene (V[TCNE]x, x~2) via low temperature chemical vapor deposition (CVD). This optimized recipe yields an increase in Curie temperature from 400 K to over 600 K and a dramatic improvement in magnetic resonance properties.

Columnar zinc oxide structures in the form of rods are synthesized via aerosol-assisted chemical vapor deposition without the use of pre-deposited catalyst-seed particles. This method is scalable and compatible with various substrates based on either silicon, quartz or polymers.
FAQs
These variables control the process conditions used to form the track and therefore influence melt-pool behavior and final bead geometry. Energy input, travel speed, and feed rate are evaluated as a set rather than in isolation, because changing them can alter how the deposited material melts, flows, solidifies, and bonds to the substrate. Parameter studies establish suitable settings for later multilayer builds.
The melt pool links heat transfer, material flow, solidification, and bonding in one localized region. Its behavior determines whether the deposited line develops the intended geometry and achieves effective attachment to the substrate. Examining this region helps explain variations in track quality and provides a basis for adjusting processing conditions before applying the method to more complex builds.
Researchers examine bead shape, dilution, porosity, and defects to assess the resulting track. Bead shape shows the geometry produced by the deposition conditions, while dilution describes the interaction reflected in the deposited region and substrate. Porosity and other defects indicate imperfections in the track. Together, these measurements support systematic optimization of deposition parameters.
A study begins with a substrate, selected powder or wire feedstock, and a moving heat source. The heat source creates a localized melt pool while the feedstock is delivered to form one continuous track. After deposition, the track is examined for bead shape, dilution, porosity, and defects. Those observations are then used to evaluate the selected process parameters.
The process requires a substrate, a heat source that moves along it, and material supplied as either powder or wire. The heat source melts the feedstock within a localized melt pool, allowing the material to form and bond as a track. These elements provide the controllable setup needed to study how deposition conditions affect the resulting geometry and quality.
Single-track trials provide a controlled way to evaluate deposition behavior before process complexity increases. By varying energy input, travel speed, or feed rate and then measuring bead shape, dilution, porosity, and defects, researchers can identify promising conditions. The resulting knowledge supports parameter selection and optimization for directed energy deposition and related multilayer additive-manufacturing processes.
