Effect of Process Parameters on a Metallurgical Route Providing Nano-Structured Single Phase Steel with High Work-Hardening

New experimental results using different prestrains and different recovery durations highlight an efficient metallurgical route to produce single phase steels with high combination between yield stress and strain-hardening. This is achieved by exploiting the thermal stability of mechanically induced twins in a high manganese austenitic Twining Induced Plasticity alloys.
