My plan to shoot 2 videos releasing CWF info got delayed by a nasty cold – lost voice.
Up & about, I shot a 95 seconds no-talk video.
Conventional hardened D2 known to be brittle. At 67rc should be like glass. At below transition temperature, this blade should behave like a thin sugar glass.
CWF ht (hardened) D2 at 67rc LN2 freezed did well with hammer tapped through 16D nail.
Close up on edge afterward
Thermal expansion sounds boring but you will probably hear more about it in CWF disclosure.
Look at CPM154 (a precious nugget of) data on Coeff of Therm Exp). It’s not a shocker to see high alloy steels transition temperature way above 0C.
Researchers fancy-up ways to create actual structure to combat thermal expansion: basically to preserve strength, minimize dimension flux and toughness in structural environment.
CWF conceptual approach is doing the same but within material/matrix itself.
LOL – I was puzzled to received a heavy package. Heheh ammo cans…
Edit to add:
My lazy & simple way of CWF ht weave – big ammo can 2/3 full of heavy cooking oil get heat ramp from a 100K BTU propane (turkey fryer) burner.
