Abstract

Thanks to the measurements of the Bauschinger effect and the twin volume fraction, the local stress within twins in Twinning Induced Plasticity (TWIP) steels has been experimentally determined. It is found that this local stress rapidly increases as a function of plastic strain to levels higher than 2GPa and can be probably higher than 3GPa for strains larger than 0.2. Mechanisms suitable to explain this order of magnitude are briefly discussed.
