Hi Brian,
Günter, as usual, did an excellent job explaing what eutectic compositions
are and what they do. The origin of eutectic compositions and Solidus and
Liquidus lines comes, to my knowledge, originally from the steel industry.
The reason I write this is that I am surprised that even you have fallen into
the sloppy language trap.
There are Solidus and Liquidus temperatures for each composition—I capitalize
them because the properly should be defioned proper nouns even though the OAD
does not define them as such. However, there is no such word as liquidus as
in "...will not attain liquidus..." An alloy may become liquid or liquify, but
cannot become 'liquidus', or even 'liquidous' for that matter.
One of the reasons people have started this misuse is, IMHO, that often these
words are not capitalized.
Werner
