Talk:Superalloy

From Wikipedia, the free encyclopedia

Superalloy a chemistry term that deals with temperture resistant metal like nikel. What do you know about superalloy? If you know something good rite it it will teach people who don't know that much about it some cool new facts and even something they can use.Do you know an elment like carbon, magneesium, or nikel that is heat resistant? If you do that's great, tell someone who does'nt know about superalloy and some heat resistant elements.

[edit] FCC Alloy?

What is FCC? (Surely not the Federal Communications Commission.)Lou Sander

FCC stands for face-centered cubic crystal structure. --Shaddack 22:19, 17 May 2006 (UTC)

[edit] Jargon

I'm not sure whether the correct tag is context (which I've used for the moment) or confusing or something else, but this article is, at the time of this writing, abuzz with copious unexplained technical language, such that a person with only one or two semesters of chemistry in his background has difficulty reading it. The technical information should probably not be removed, but more of it needs to be _explained_ better. For a layperson, the article on tungsten arguably gives more accessible information about superalloys than this article does.

As far as I can see, it is only the "Chemical development" and "Scientific facts" sections that are impossible to understand. Are you worried about other sections, too? RandomP 17:13, 2 June 2006 (UTC)

[edit] Crystal Structure of Gamma prime

Can someone check if the crystal structure is indeed fcc and not primitive cubic? I think it might be primitive cubic or Cubic-P (see Cambridge website).

- any, if you hin at gamma prime. This structure is called L12.
 here is picture:

 Its looks like fcc, but isn't.

 This is typical misunderstanding between lattice and crystal structure
 Crystal structure is result of assignation of some ornament to space lattice.

Lattice is only math term no more. And L12 cann't be derived from cubic face centred lattice. THE PROBLEM is that this same term FCC IS USED FOR 2 DIFFERENT THINKS. First is name of lattice and second is name of crystal structure where each corner is occuped by atom of this same element. So Cambridge website is true that thid structure can be derived only from Primitive Cubic latice, but the name of this structure is L12

[edit] FCC Alloy

Interesting in one paragraph Ni3Al is correctly described as L12 and in one incorrectly as FCC
