What are the crystal structures and lattice parameters of CoIr alloys?

Click For Summary

Discussion Overview

The discussion focuses on the crystal structures and lattice parameters of CoIr alloys, exploring both theoretical and practical aspects of this material. Participants seek information on the specific characteristics of CoIr, including references and data related to its crystallography.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant requests information about the crystal structure and lattice parameters of CoIr alloys, seeking references.
  • Another participant suggests a specific reference related to atomic diffusion and phase equilibria, questioning whether the inquiry is limited to the binary Ir,Co system or includes other systems like B2-(Ir, Co)Al.
  • A participant mentions using software to visualize molecular structures and inquires about the intended application of the alloy's structure.
  • One participant notes the Naval Research Lab's website on crystal structures but finds no specific information on Ir-Co, suggesting it might be an intermetallic or a solid solution.
  • A participant provides specific lattice parameters for CoIr, indicating it has hcp crystallography and lists various parameters such as cell volume and angles.
  • Another participant agrees that the hcp structure aligns with a solid solution of Ir in Co, contrasting the crystallographic structures of Co and Ir.

Areas of Agreement / Disagreement

Participants express varying views on the nature of the CoIr alloy, with some suggesting it may be a solid solution while others consider it an intermetallic. The discussion remains unresolved regarding the specific classification and characteristics of CoIr alloys.

Contextual Notes

There are limitations regarding the completeness of the information provided, including potential missing assumptions about the alloy's properties and the definitions of terms used in the discussion.

I am looking for informations about CoIr alloys.
Who can tell me about crystal structure, lattice parameters of CoIr alloy?
Please share me some references about this material.
Thanks! :!)
 
Engineering news on Phys.org
wow astronuc you really pinned down that question :-p

btw i remember using this software called 'diamond' that would let you look at the structure of molecules of minerals, twas pretty cool.

edit: iron and copper

just wondering what will you do once you have the structure of the alloy?

The Naval Research Lab has a website on crystal structures. I didn't readily find Ir-Co. I thought it might be an intermetallic, but I have seen references to a solid (substitutional) solution.

I have found that CoIr has hcp crystallography with:
Z 2
a 0.2602 nm
b 0.2602 nm
c 0.4183 nm
a 90 °
b 90 °
g 120 °
Cell volume 0.02453 nm-3
a/b 1.000
b/c 0.622
c/a 1.608
