There has been a lot of discussion in the Sport Fencing community about the effects of relative cold temperatures on fencing blades and the need to "warm them up" using friction to 'Room Temperature' prior to use. The temperatures that I am referring to are between -20 degrees F and 50 degrees F. Many fencers claim that if the blades are not warmed up thathtey become brittle and are more prone to breakage if they are not warmed up.
The general kinds of stresses applied to these blades are impact (blade to blade contact, blade to guard contact and blade to 'target' contact) and flexing in a single plane.
Steels used in these blades are either of Maraging steel or of — 45Si7, 45Si Cr Mo, 45 XH2 MFA.
My assumption is that these temperature ranges would have minimal effect tothe ductility of the metals, but is has been a LONG time since my failure analysis class, and I was never that good in my chemestry. Any thoughts on this would be nice.
