Machining Waspaloy The Fiercest Super Alloy Youve Never Seen

I learned a bit more about something I knew very little about before.....

Waspalloy.

( make it plural and a range of alloys )

Distant recollection:

Developed in the 30's and 40's as heat resistant exhaust valve materials...

And spun over into gas turbine components / rocket engine parts....

I could pull out some metallurgy / engineering books and scan / Optical character recognition a heap of text and tables etc.. and paste it in here...

People really are so fucking clever.... AND I am more pig ignorant about so many things, than I have experience or working knowledge of.....

So this is a good video.

BUT I would have thought a high strength bolt made from this material, would have been forged to shape on the head, and roll formed on the thread.

Tough as all of that may be...

Maybe this is just a machining demo.

The British Aircraft Corporation TSR-2, a supersonic strike aircraft developed from the late 1950s, had a fairing to its rear fuselage around the exhaust nozzles. Owing to the high temperatures in this area, the fairing was formed of Waspaloy and left unpainted. Fabrication of this alloy was described as 'very intractable' and was carried out by the engine specialists Bristol, rather than the airframe builders BAC.[6]

Most of the links are dead.... Things can be refound though.
