Webb1 juni 1998 · 1. Introduction. The Piobert–Lüders behavior is a plastic instability which occurs in steels containing interstitial elements in solid solution such as carbon or nitrogen. These elements may segregate to dislocations during aging and lock them. Under a subsequent tensile test, the specimen thus exhibits a strain localization oriented … WebbPiobert's law applies to the reaction of solid propellant grains to generate hot gas.
