Deformation Mechanism Investigation on Low Density 18Mn Steels under Different Solid Solution Treatments
2021
Metals
To meet the demand of the 10% weight reduction goal for automotive steel, the microstructure and mechanical properties of Fe–18Mn–Al–C steel with different carbon and aluminum contents were investigated under different solid solution treatments, and the deformation mechanisms of the experimental steels were elucidated. Aided by thermodynamic calculation, transmission electron microscopy (TEM) and in situ scanning electron microscope (SEM) analysis, it was shown that for the 18Mn–1.5Al
