Sorry for the late reply, but thank you so much for the info! This was very helpful! Oh, I see, so it would be best to melt those pairs together first ( Ir-Rh, W-Mo and Ta-Nb), before melting all the pairs together in a vacuum arc furnace?

Equal amounts in proportion by mass (%), so 16.6% each, ideally. Would you recommend an arc vacuum melting method for this? Just to get the metals mixed together and hopefully with no insolubility

A ring for a wealthy acquaintance

Okay so now the line up is: Tungsten-Iridium-Tantalum-Molybdenum-Rhodium-Niobium Would melting together equal parts of Tungsten, Iridium, Tantalum, Molybdenum, Rhodium, Niobium create a substitutional solid solution or become intermetallic? I think intermetallic means, in this case, they...

Wait, you're right, Titanium and Silver would boil off. I'll have to look for an alternative metal

Tungsten is the highest of the six, so we'll go with that temperature (Tungsten's melting point). It's going to be higher than Osmium and Silver anyway. I just realized that Osmium, Chromium, and Vanadium may be toxic so I'm replacing it with Titanium, Molybdenum, and Tantalum instead. I think...

Maybe put each in separate foundries, each foundry heated up to either the metal's melting point or just all at whichever metal has the highest, and then once all metals are melted, pour all 6 together in an empty 7th foundry

Purpose is to make a ring.
