My wedding ring (made by a friend) is made of a gold/
titanuim alloy. It is a proprietary technique, but it
involves alloying pure gold with .5% of titanium, so
it still assays as 24 karat gold, with the true color
of 24 karat, but with the hardness of a standard 18
karat alloy, which makes it more suitable for the rough
use that hand jewelry tends to get.

Good Day to All ,
Thank you twice,
Michael ,
for the Snail Scott oversight and for the extremely
helpful information . At least I know where to look
now.
Here's my new years question for you.
What is the highest expansion clay body that might
be created [ vitreous if possible ] ?
Or I am trying to fit some of my strange alkaline
frits to a body , and need a push start - help .

Yes, you can alloy virtually any metal with another. But not necessarily by
fusing them.
Alloying a high melting point metal with a low melting metal such as lead
and titanium for example requires other methods, such as powder sintering
(using high pressure and/or heat), or high-energy cold ball-milling. Simple
heating of a mix of titanium and lead results in the lead boiling prior to
the titanium melting. The amalgams resulting from non-fusing methods often
have spectacular eutectics.
The second method (ball-milling metal powder) can allow alloys to be
prepared from immiscible or unreactive metal mixtures.
