SUMMARY:Effect of isothermal bainite formation, below the Ms temperature, on tensile properties of a medium-carbon, low-alloy advanced high strength steel 
DESCRIPTION:Abstract:

Isothermal bainitic transformation below the Martensite start temperature (MS) has been reported in previous works [1,2]. The current study investigates the effect of bainite formation below the MS temperature where the athermal martensite formation is interrupted, on the final tensile properties. The studied material is a 0.4 (wt.%) carbon, low-alloy steel subjected to different thermal cycles in order to produce different fractions of martensite and bainite. Gleeble 3800 thermo-mechanical simulator machine was employed to perform all the cycles as well as to provide the dilatometric data. In the experiments, each sample was heated to the temperature of 850 °C at a rate of 50 °C/s and was held for the 30s. Then, the samples were quenched to a temperature between MS and MF followed by a subsequent isothermal holding in the MS–MF temperature window. A field emission scanning electron microscopy equipped with an electron back-scatter detector was used for microstructural characterization. The results showed that low-temperature bainite formation below the MS significantly improved the ductility of the samples although the strength decreased slightly.
