Crucible steel blades

Thank you Jens.

As far as I remember a lot of steels become brittle at temperatures around 0 centigrade; I doubt that one can fight or even run at minus 40 degrees, so most likely we must look at higher temperatures.

Concerning phase transitions - I have no idea about the topic, but 20-30 degrees change in temperature - can it force a fast phase transition ? Or it will take 200 years for the transition to occur ?
I think the cause here is a simple brittleness.
