Discussion Overview

The discussion revolves around the formation of an aluminum-titanium alloy using a flux of each element deposited onto a substrate, specifically exploring the implications of varying flux ratios and deposition methods. The focus includes theoretical aspects of alloy formation, material properties, and deposition techniques.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant questions whether a flux of aluminum that is double that of titanium will yield an alloy of AlTi or another composition.
  • Another participant suggests that the goal may be to create titanium aluminide (TiAl) or Ti3Al, noting the interest in various intermetallic compounds.
  • A participant emphasizes that the type of substrate is not the primary concern, but rather the pulverization of aluminum and titanium to deposit an alloy, questioning the resulting alloy based on the flux ratio.
  • There is a clarification regarding whether the flux ratio is considered on an atomic or mass basis, with speculation about the potential formation of Ti-Al and Ti-Al3 alloys.
  • One participant confirms that the deposition method is sputtering.
  • Another participant argues that calculating the exact alloy composition is not feasible without specific process parameters and suggests that extensive experimentation and analysis are necessary to determine the outcomes.

Areas of Agreement / Disagreement

Participants express differing views on the implications of the flux ratios and the resulting alloy compositions, indicating that multiple competing perspectives remain without a consensus on the specific outcomes of the deposition process.

Contextual Notes

Participants note that the deposition method and process parameters, such as temperature and equipment specifics, significantly influence the alloy formation, highlighting the complexity of the experimental setup.

Al and Si?? flux??

to creat a film of alloy Al and Ti we use to flux of each element and a substrat.
if the flux of Al is double of that of Ti, then we obtain an alloy on the substrat AlTi or what?

What is the substrate?

I believe the goal is something like TiAl (titanium aluminide), although Ti3Al is apparently of interest as well.

See - http://www.azom.com/details.asp?ArticleID=1548
Aluminides are intermetallic compounds. A wide range of potentially useful alloys of these have been investigated with attention now concentrated on gamma (Ti-Al) and orthorhombic alloys. Alpha and super-alpha compositions (TiAl3 based) are no longer of significant interest.

its not about the type of substrat. its about a pulverisation of two source Al and Ti do depose an alloy on the substrat. if the flux of Al pulverized equal = 2* flux of Ti, so which alloy we obtain??

Is that on an atomic basis? or mass, which would be different.

With Al = 2*Ti, I would imagine a mix of Ti-Al, and Ti-Al3, not knowing anything other information.

Is this a plasma spray, vapor deposition, or sputtered coating?
 
its sputtering
 
Again, you can't calculate it. If it is done usings sputtering (what kind?) you have a few process parameters to play around with; mainly temperature.
For practical film depostion it will also -to some extent- be specific to the equipment you are using.
The only way to do this properly is to deposit a lot of films under different conditions and analyze them (using XRD and some type of surface spectroscopy, e.g. Auger): this will give you a "map".
