What is a "divacancy"
What is a "divacancy"
(OP)
I recently came across an explanation that attributed a behavior (corrosion fatigue, if you must know) to the formation of "divacancies". Wiktionary defines a divacancy as:
A pair of vacancy defects in a crystal.
I am a member of ASM and a search through the journals available on their website (Like Met Trans A) did not reveal anything. I would not have expected it to.
Can someone please shed some insight on what a divacancy is?
Maybe a link to a website with an illustration, or a more intuitive explanation.
How is a divacancy different from a vacancy?
What is special about divacancies?
A pair of vacancy defects in a crystal.

May I supplement my posting to include a request for a short summary by a member, or an illustration of what a divalency "looks like" or why they are important to metallurgists?

Funny that you would link me to that particular article. That is the very article that caused me to wonder what a divancancy is.
I understand what the article says about the action of divacancies, but what is a divacancy?
Is there any other mechanism that depends on divacancies?
What does one look like (obviously schematically)?
I guess I am a visual thinker.

That was a terrific response. I wish I could give you more than one star. A link to a sketch, and another link to a concise description.
Exactly what I wanted.
Thanks again.
