Thermo-mechanical Hardening of Ultra High-Strength Steels

Innovative ultra high-strength steels have excellent mechanical properties which commonly relate to the material's martensitic microstructure. As thermal heat treatments are state-of-the-art for obtaining the desired microstructure, innovative thermo-mechanical treatments are likely to give rise to even better material qualities. This article highlights various aspects of innovative thermo-mechanical hardening strategies for the processing of ultra high-strength steels, involving both press hardening and friction spinning operations.
