12. Alloy preparation
On the whole, the data selected are those obtained from the purest metals, which is the case of the most recent publications, and those in which contamination from the atmosphere or the crucible in which the alloy is made is the lowest.
After production, alloys must undergo homogenization annealing and, if necessary, extensive wrought-ironing, to reduce diffusion distances and increase the number of defects, which accelerates diffusion, but also to induce recrystallization, which activates atom mobility and can also refine the grain, thus facilitating certain subsequent transformations.
The difficulty of obtaining states as close as possible to equilibrium often necessitates the use of indirect manufacturing methods. Instead of solidifying liquid alloys, it is often safer and quicker, when the risk of contamination is not too great, to anneal...

Diagram classification
In this folder, the diagrams are arranged in alphabetical order of the symbol of the element concerned, which comes first in alphabetical order among the elements making up the alloy; then, for a given element, in alphabetical order of the symbol of the second element.
Example
we find Fe-C to C-Fe.

This diagram has recently been completely revised. The relationships between phases and their compositions are now well known; there are apparently no other intermediate phases richer in arsenic than those shown in the diagram.
