Absolutely fascinating plethora of different shapes!

Thanks to @gigabecquerel for doing your SEM magic and taking those stunning pictures!

I wish we had an XRF detector to see the distribution of the different elements...

Toot

Written by std_logic_vector on 2024-08-27 at 21:13

Although those pictures are neat, I wanted to try again and get a properly mixed and melted ingot of alloy.

Suspecting the oxidation of the powder particles as the reason for the improper melting I wanted to try bigger pieces of metals.

So this time I used manganese flakes, aluminium drops and copper wire. And for good measure some sodium chloride as a flux and further protection from oxygen.

Bake at 1400°C for 60min and enjoy!

@stdlogicvector can you flood the furnace with argon?

@stripey That would be a possibility, but it's expensive. I'll do more tests with flux first.
