Kodachrome. It gives you nice bright colors.

Those were such good days.....

A few years ago I was having a late dinner and I mentioned to my waitress a 70s band that had a local concert.

She then told me that the band would be having dinner at the table next to me in a few minutes.

When they got up after dinner the drummer looked at me, nodded and smiled and I said “Can we go back to when you guys were on the radio? Things were so much better back then!”

[Does so]

And insulated coffee cups.”

YETI says the interiors are brass. (Exteriors are stainless steel).

Copper-beryllium alloys have been used for firing pins...

The new Cu-Ta-Li coffee mugs will be better. :)

I see no reference to fracture toughness.

Lack of fracture toughness is always the achilles heel of these “wonder materials”.

"..on the scale of nickel-based superalloys..."

HRSA's baby! Heat Resistant Super Alloys. I machine this stuff all day long for a living and yeah its some crazy cool material. That whole HRSA line is. Its amazing how it can be glowing bright orange hot and still maintain its mechanical properties. I think Kelly Johnson of the 1960's Skunk Works era first made it famous.
