Abstract


  • Increasing demand for automotive vehicles with reduced weight, improved

    crashworthiness and passengers safety has steamed the research of new Twinning Induced Plasticity

    (TWIP) steels. In this work the effect of annealing between 400 and 900oC on the microstructure

    and mechanical properties of hot and cold rolled 0.06C-24Mn-3Al-2Si-1Ni (wt%) steel with TWIP

    effect was investigated. The results have shown that steel exhibits fast recrystallization kinetics with

    a low amount of recovery, which results in a high driving force for the former. Mechanical

    properties were determined using Vickers microhardness and tensile tests. Tensile strength of 670

    MPa with 54% of total elongation, and strain hardening exponent of 0.57 were reached after

    annealing at 900°C.
