Dear List-Members,
A couple of metallographic questions on my desk at the
moment:
Has anybody any experience of examining the corrosion of
Cu-Sn beta martensites. The example I have is medieval but
data from any period are welcome.
Does anybody know of any very recent publications (say last
two-three years) on the compositions of PGE inclusions in
gold? The example I am concerned with is Os/Ir with a small
percentage of Ru.
